By Charles L. Geshekter
The problem with the truth is that it is mainly uncomfortable and often dull . -- H.L. Mencken
Millions of Africans have long suffered from severe weight loss, chronic diarrhea, fever, and persistent coughs. In 1985 Western researchers suddenly defined this cluster of symptoms as a distinct syndrome, AIDS, and declared that it was caused by a single virus, HIV, which they considered to be sexually contagious.(1)
American health officials universally accept this HIV-AIDS model to explain what used to be considered the diseases of rampant poverty in Africa. There are at least three reasons why this view needs careful reconsideration.
First is the fact that many of the Africans who qualify for AIDS diagnoses -- perhaps as many as 70% -- turn out to be negative when tested for HIV.
Second is the failure of the African HIV-AIDS model to predict the course of AIDS in the United States. Since AIDS symptoms are widespread in the general African population,(2) if it transmits heterosexually it should also become widespread in other general populations, such as Americans, in which hundreds of thousands of heterosexuals annually contract venereal diseases. Instead, 16 years after it was first described in the medical literature, in the United States AIDS has remained rigidly confined to special risk groups. Of the 70,000 annual American AIDS patients, at least 90% are drug users (including nearly all the gay patients), and fewer than 10,000 are designated as heterosexual cases.
Third, sexual transmission can't explain the differences in rates of HIV positivity between African (about five per 100) and American (about one per 7,000) heterosexuals. When the HIV-AIDS paradigm made its debut in 1984, its proponents assumed that HIV was easily transmitted coitally. Scientists tested this idea only years later, though, when they arrived at extremely low coital transmission frequencies. The latest study shows that an HIV-negative woman converts to positive on average only after one thousand unprotected contacts with a positive man, and a negative man becomes positive on average only after eight thousand contacts with a positive woman.(3)
These data suggest two mutually exclusive conclusions. Either HIV isn't a sexually transmitted microbe after all, and other factors account for HIV prevalence; or African heterosexuals are wildly more promiscuous than American heterosexuals, a scenario that surely is not true.
With all of this in mind, why do so many health professionals consider it useful or necessary to view the diseases of poverty in Africa as sexually contagious? And why did they ever believe it?
Defining AIDS in Africa
CDC physicians Joseph McCormick and Susan Fisher-Hoch convened the WHO conference in the Central African Republic in 1985 that produced the "Bangui Definition" of AIDS in Africa. The CDC had just adopted the HIV-AIDS model to explain the diseases of American drug injectors, a cohort of promiscuous urban gays in the party drug scene, and transfusion recipients. HIV turned out to be one of the many viruses that tended to react with blood from these patients. The same was true of blood from Africans afflicted with the diseases of poverty. The HIV-AIDS model assumed that AIDS would "spread" via HIV to a much larger fraction of Africans than those who currently suffered from it.
McCormick and Fisher-Hoch accepted this model. They recently explained their motivation for the conference and the rationale behind the AIDS definition that resulted from it: We still had an urgent need to begin to estimate the size of the AIDS problem in Africa....But we had a peculiar problem with AIDS. Few AIDS cases in Africa receive any medical care at all. No diagnostic tests, suited to widespread use, yet existed...In the absence of any of these markers [e.g., diagnostic T4/T8 white cell tests], we needed a clinical case definition...a set of guidelines a clinician could follow in order to decide whether a certain person had AIDS or not. [If we] could get everyone at the WHO meeting in Bangui to agree on a single, simple definition of what an AIDS case was in Africa, then, imperfect as the definition might be, we could actually start to count the cases, and we would all be counting roughly the same thing. [emphasis added]
The definition was reached by consensus, based mostly on the delegates' experience in treating AIDS patients. It has proven a useful tool in determining the extent of the AIDS epidemic in Africa, especially in areas where no testing is available. Its major components were prolonged fevers (for a month or more), weight loss of 10 percent or greater, and prolonged diarrhea.(4)
The doctors wanted to refute the ugly moralism of the 1980s that AIDS was a "gay plague" by convincing the American government that "AIDS was a plague all right, but that no one was immune."(5)
McCormick and Fisher-Hoch recalled that: experts in STDs continued to regale us with tales of the excessive and often bizarre sexual practices associated with HIV in the West... We were also beginning to see a direct correlation between the number of sexual partners and the rate of infection...Compared to the West, heterosexual contacts in Africa are frequent, and relatively free of social constraints -- at least for the men.... There was every reason to believe that, having found heterosexually transmitted AIDS in Kinshasa, we were likely to find it everywhere else in the world.(6)
It was upon these grossly unscientific claims, inaccurate clinical generalizations, western notions of sexual morality, and 19th-century racist stereotypes about Africans that AIDS became a "disease by definition." Africa was assigned a central role in promoting the premise that AIDS was everywhere and everyone was at risk. By 1986, "people were falling over one another to get involved in AIDS research," recalled the couple. "They realized that AIDS represented an opportunity for grant money, training, and the possibility of professional advancement... A certain bandwagon mentality took hold. Careers and reputations were riding on the outcome."(7)
As proof that these "AIDS symptoms" were sexually transmitted, McCormick and Fisher-Hoch point to a narrow survey conducted by Kevin DeCock, another CDC epidemiologist. In 1986, DeCock examined stored blood samples taken in 1976 (for Ebola virus testing) of 600 residents of the small town of Yambuku, in northern Zaire. Samples from five patients (0.8%) tested positive for HIV antibodies.
DeCock wanted to know what happened to those five people during the intervening ten years. According to McCormick and Fisher-Hoch, "three of the five [60%] were dead. To determine if their deaths were attributable to AIDS, Kevin interviewed people who had known them. The friends and relatives of the deceased described an illness marked by severe weight loss and other ailments that left little doubt in Kevin's mind that they had succumbed to AIDS [emphases added]."(8)
DeCock concluded from these interviews that the dead subjects died from AIDS, and that HIV had caused it. He reached this conclusion without properly matching the five HIV-positive patients with peers from among the 595 HIV-negative subjects, and without collecting mortality data and morbidity information about them as well. Had he done this, perhaps he would have discovered that even HIV-negative Africans die of "severe weight loss" and other so-called AIDS conditions.
DeCock further noted that antibody tests conducted in 1986 showed that the HIV prevalence in Yambuku had remained constant at 0.8% during the ten years since 1976. As far has he was concerned, this meant that HIV -- and thus AIDS -- really did originate in Africa. HIV (AIDS) existed for years in small numbers of rural inhabitants (who had contracted the HIV from primates, he imagined). He speculated that once some of those people in the late '70s migrated to what DeCock falsely assumed were sex-crazed cities, an epidemic of HIV and AIDS exploded.
DeCock did not consider that these same data could have been interpreted as indicating that HIV is a mild virus, and difficult to transmit. Neither did McCormick and Fisher-Hoch.
The sort of presumptive diagnosis employed by DeCock is known as a "verbal autopsy." It is widely accepted in Africa, where "no country has a vital registration system that captures a sufficient number of deaths to provide meaningful death rates."(9)
While medically certified information is available for less than 30% of the estimated 51 million deaths that occur each year worldwide, the Global Burden of Disease Study (GBD) found that sub-Saharan Africa had the greatest uncertainty for the causes of mortality and morbidity since its vital registration figures were the lowest of any region in the world -- a microscopic 1.1% (10)
These findings prompted The Lancet to acknowledge editorially that "current strategies to improve the world's health may need to be reassessed" and to ponder "how much more money is spent on research into HIV infection [the 30th cause of death] than into the causes of suicide [#12] or the prevention of road-traffic accidents [#9] and why should this be."(11)
Racism and African Sexuality
Whereas AIDS in the industrialized countries almost exclusively confines itself to a tiny percentage of homosexuals, drug injectors, and transfusion patients, AIDS afflicts the same general African population that faces such ancient scourges as malaria, schistosomiasis, and sleeping sickness (trypanosomiasis).
This is known as the "heterosexual paradox" of AIDS. Champions of the HIV model attempt to explain it in two contradictory ways. Some simply declare that the paradox is temporary. They speculate that HIV arrived first in Africa and, in time, AIDS will be just as rampant in the West. However, they've been saying this now for over ten years.
Others recognize the permanence of the paradox. They account for it by declaring that Africans are just different from Westerners. They are substantially more promiscuous and more likely to have genital ulcers. How else to explain the widespread distribution of a virus that requires, for non-ulcerated genitals, a thousand heterosexual acts?
At the 10th International AIDS Conference in Yokohama (August 1994), Dr. Yuichi Shiokawa claimed that AIDS would be brought under control only if Africans restrained their sexual cravings. Professor Nathan Clumeck of the Universite Libre in Brussels was skeptical that Africans will ever do so. In an interview with Le Monde , Clumeck claimed that "sex, love, and disease do not mean the same thing to Africans as they do to West Europeans [because] the notion of guilt doesn't exist in the same way as it does in the Judeo Christian culture of the West."(12)
Such racist myths about the sexual excesses of Africans are old indeed. Early European travelers returned from the continent with tales of black men performing carnal feats with unbridled athleticism with black women who were themselves sexually insatiable. These affronts to Victorian sensibilities were cited, alongside tribal conflicts and other "uncivilized" behavior, as justification for colonial social control.
AIDS researchers added new twists to an old repertoire: stories of Zairians who rub monkeys' blood into cuts as an aphrodisiac, of ulcerated genitals, and of philandering East African truck drivers who get AIDS from prostitutes and then go home to infect their wives.(13)
A facetious letter in The Lancet even cited a passage from Lili Palmer's memoirs as evidence for how a large male chimpanzee's "anatomically unmistakable signs of its passion for [Johnny] Weismuller" on the Tarzan set in 1946 "may provide an explanation for the inter-species jump" of HIV infection.(14)
No one has ever shown that people in Rwanda, Uganda, Zaire, and Kenya -- the so-called "AIDS belt" -- are more active sexually than people in Nigeria, which has reported only 3,002 cumulative AIDS cases out of a population of 100 million, or Cameroon, which reported only 8,141 cases in 10 million. (15)
No continent-wide sex surveys have ever been carried out in Africa. Nevertheless, conventional researchers perpetuate racist stereotypes about insatiable sexual appetites and carnal exotica. They assume that AIDS cases in Africa are driven by a sexual promiscuity similar to what produced -- in combination with recreational drugs, sexual stimulants, venereal disease, and over-use of antibiotics -- the early epidemic of immunological dysfunction among a small sub-culture of gay men in the West.(16)
The research from Africa suggests nothing of the sort. In 1991 researchers from Medicins Sans Frontieres and the Harvard School of Public Health did a survey of sexual behavior in the Moyo district of northwest Uganda. Their findings revealed behavior that was generally not very different from that of the West. On average, women had their first sex at age 17, men at 19. Eighteen per cent of women and 50% of men reported premarital sex; 1.6% of the women and 4.1% of the men had casual sex in the month preceding the study, while 2% of women and 15% of men did so in the preceding year. (17)
The media misrepresentations that link sexuality to AIDS have spawned inordinate anxieties and moral panics in regions of Africa already afflicted with extreme poverty, ravaged by war, and deprived of primary health care delivery systems. The "disaster voyeurism" of tabloid journalism enables them to use AIDS to sell "more newspapers than any other disease in history. It is a sensational disease -- with its elements of sex, blood and death it has proved irresistible to editors across the world."(18)
Public health seems to require salesmanship, not skepticism. The media's appetite for scary scenarios and its disdain for alternative perspectives enables it to treat Africa in apocalyptic terms. This marketing of anxiety helps to promote behavior modification programs to "save Africa." Oblivious to the morbidity and mortality data from the Global Burden of Disease Study, journalists reflexively maintain that "AIDS is by far the most serious threat to life in Africa."(19)
The serious consequences of claiming that millions of Africans are threatened by infectious AIDS makes it politically acceptable to use the continent as a laboratory for vaccine trials and the distribution of toxic drugs of disputed effectiveness like ddI and AZT. On the other hand, campaigns that advocate monogamy or abstinence and ubiquitous media claims that "safe sex" is the only way to avoid AIDS inadvertently scare Africans from visiting a public health clinic for fear of receiving a "fatal" AIDS diagnosis. Even Africans "with treatable medical conditions (such as tuberculosis) who perceive themselves as having HIV infection fail to seek medical attention because they think that they have an untreatable disease."(20)
Some Western scientists, including Dr. Luc Montagnier, the French virologist who discovered HIV, claim that the practice of female circumcision facilitates the spread of AIDS.(21)
Yet Djibouti, Somalia, Egypt, and Sudan, where female genital mutilation is the most widespread, are among the countries with the lowest incidence of AIDS.
Does the "AIDS epidemic" in Africa portend the future of the developed world? The scientific establishment certainly thinks so. Biomedical funds that had been earmarked to fight African malaria, tuberculosis, and leprosy are now diverted into sex counseling and condom distribution, while social scientists have shifted their attention to behavior modification programs and AIDS awareness surveys.
Good Intentions, Bad Science: HIV Tests and Disease
A reappraisal of AIDS in Africa must recognize that HIV tests are notoriously unreliable among African populations where antibodies against endemic conventional viruses and microbes cross-react to produce ludicrously high false-positive results. For instance, a 1994 study on central Africa reported that the microbes responsible for tuberculosis and leprosy were so prevalent that over 70% of the HIV-positive test results there are false.(22)
The study also showed that HIV antibody tests register positive in HIV-free people whose immune systems are compromised for a wide variety of reasons, including chronic parasitic infections and anemia brought on by malaria.
The very low frequency of vaginal transmission of HIV makes it hard to imagine that heterosexual transmission can be responsible for high rates of HIV prevalence observed in some regions.(23)
So what is responsible?
Perhaps the tests used to determine HIV infection in Africa overstate the prevalence. Some HIV tests detect entities believed to be part of HIV itself, such as certain proteins or genetic sequences. But in Africa HIV prevalence is determined by testing for antibodies, which are components of the host immune system, not the virus. The fact that these tests react with antibodies triggered by ordinary African microbes suggests an explanation for HIV prevalence in Africa that is more plausible than sexual transmission. (24)
Even the association of HIV antibody tests with ordinary infections does not mean that positive results warrant a prognosis of death. Consider an investigation, reported in The Lancet , of 9,389 Ugandans with unequivocal HIV antibody test results.(25)
Two years after enrolling in the study, 3% had died, 13% had left the area, and 84% remained. There had been 198 deaths among the seronegative people and 89 deaths in the seropositive ones. Medical assessments made prior to death were available for 64 of the HIV-positive adults. Of these, five (8%) had AIDS as defined by the WHO clinical case symptoms. The self-proclaimed "largest prospective study of its kind in sub-Saharan Africa" had tested nearly 9400 people in Uganda, the so-called epicenter of AIDS in Africa. Yet of the 64 deaths recorded among those who tested positive for HIV antibodies, only five were diagnosed as AIDS-induced.
If it is not sexual transmission of HIV, then what causes the widespread appearance of AIDS symptoms throughout Africa? The evidence strongly implicates the ordinary, widespread socio-economic conditions that give rise to AIDS symptoms even among HIV-negative Africans.(26)
In her meticulous 1997 doctoral dissertation, Michelle Cochrane juxtaposed the central tenets of AIDS orthodoxy against the material record of San Francisco AIDS patients' charts. She found that public health officials persistently over-estimated the risk of contracting HIV/AIDS through sexual activity, "while simultaneously under-estimating the proportion of the HIV/AIDS caseload that were attributable to intravenous drug use and/or socio-economic factors which condition access to health care and prevention services."(27)
Cochrane showed that health officials conspicuously failed to investigate all risk factors for immunological dysfunction among heterosexual adult females.In their surveillance studies, it was considered sufficient for a heterosexual female merely to claim that the source of her infection was sex with an IV-drug user or another man at risk for HIV/AIDS... A percentage of the 187 female AIDS cases [out of 24,371 cumulative cases in San Francisco] attributed to sexual transmission could, with proper investigation, be attributable to IV-drug use. Epidemiological research in the United States and Europe has never proven that a female has sexually transmitted HIV to a man. [Because] heterosexual transmission of HIV from a male to a female happens with difficulty and very infrequently... all AIDS surveillance statistics on female AIDS cases have been gathered without rigorous scrutiny of the woman's risk for disease and with a bias towards including as many women as possible [emphasis added].(28)
The a priori assumptions that directed AIDS surveillance activities in the United States subsequently allowed predictions about an exponential spread of the disease to survive as "common knowledge," despite the lack of empirical data. These are critical points to consider when reviewing any epidemiological data on "AIDS" cases in Africa.
For the period 1984-95, the WHO compared estimates of HIV seropositivity with the actual numbers of AIDS cases in its Weekly Epidemiological Reports. The cumulative result is that 99.95% of all Africans do not have AIDS -- including 97% of those who test HIV-positive. These facts strikingly contradict the popular view of an Africa overrun by fatal HIV infections.(29)
AIDS and the Medicalization of Poverty
Primary health care systems in Africa will remain hampered until public health planners systematically gather statistics on morbidity and mortality to accurately show what causes sickness and death in specific African countries. During the past ten years, as the external financing of HIV-based AIDS programs in Africa dramatically increased, money for studying other health problems remained static, even though deaths from malaria, tuberculosis, neo-natal tetanus, respiratory diseases, and diarrhea grew at alarming rates.(30)
While Western health leaders fixate on HIV, 52% of sub-Saharan Africans lack access to safe water, 62% lack proper sanitation, and an estimated 50 million pre-school children suffer from protein-calorie malnutrition.(31)
Poor harvests, rural poverty, migratory labor systems, urban crowding, ecological degradation, social mayhem, the collapse of state structures, and the sadistic violence of civil wars constitute the primary threats to African lives.(32)
When essential services for water, power, and transport break down, public sanitation deteriorates, and the risks of cholera, tuberculosis, dysentery, and respiratory infection increase.
WHO Director General Hiroshi Nakajima warns emphatically that "poverty is the world's deadliest disease."(33)
Indeed, the leading causes of immunodeficiency and the best predictors for clinical AIDS symptoms in Africa are impoverished living conditions, economic deprivation, and protein malnutrition, not extraordinary sexual behavior or antibodies against HIV, a virus that has proved difficult or impossible to isolate directly, even from AIDS patients.
The so-called "AIDS epidemic" in Africa has been used to justify the medicalization of sub-Saharan poverty. Thus, Western medical intervention takes the form of vaccine trials, drug testing, and almost evangelistic demands for behavior modification.
AIDS scientists and public health planners should recognize the role of malnutrition, poor sanitation, anemia, and ordinary infections in producing clinical AIDS symptoms in the absence of HIV.(34)
The data strongly suggest that socio-economic development, not sexual restraint, is the key to improving the health of Africans.
Medically trained charity workers Phillipe and Evelyn Krynen, employed by the French group Partage, in Kagera Province of Tanzania, report that when "appropriate treatment was given to villagers who became ill with complaints such as pneumonia and fungal infections that might have contributed to an AIDS diagnosis, they usually recovered."(35)
A similar observation comes from Father Angelo D'Agostino, a former surgeon who founded Nyumbani, a hospice for abandoned and orphaned HIV-positive children in Kenya: "People think a positive test means no hope, so the children are relegated to the back wards of hospitals which have no resources and they die. They are very sick when they come to us. Usually they are depressed, withdrawn, and silent... But as a result of their care here, they put on weight, recover from their infections, and thrive. Hygiene is excellent [and] nutrition is very good; they get vitamin supplements, cod liver oil, greens every day, plenty of protein. They are really flourishing."(36)
Conclusion
People can be encouraged to behave thoughtfully in their sexual lives if they are provided with reliable information about condom use, contraception, family planning, and venereal diseases. Multilateral institutions and African AIDS educators should familiarize themselves with the scientific literature that demonstrates the contradictions, anomalies, and inconsistencies in the HIV/AIDS orthodoxy.(37)
They have a major responsibility to consider the non-contagious explanations for "AIDS" cases in Africa and to stop the proliferation of terrifying misinformation that equates sexuality with death. *

Jack7 - 26 Apr 2004 17:05 GMT Deaths from AIDS
The human toll and suffering due to HIV/AIDS is already enormous. HIV/AIDS is now by far the leading cause of death in sub-Saharan Africa. Since the beginning of the epidemic over 15 million Africans have died from AIDS. During 2002 an estimated 2.4 million adults and children died as a result of HIV/AIDS in sub-Saharan Africa.
The Impact of HIV/AIDS in Africa
Many countries in sub-Saharan Africa have failed to bring the epidemic under control. 71% of the world's HIV-positive people live in sub-Saharan Africa, although this region contains only 11% of the world's population. There is a significant risk that some countries will be locked in a vicious cycle, as the number of people falling ill and subsequently dying from AIDS has a tremendous impact on many parts of African society, including demographic, household, health sector, educational, workplaces and economic aspects.
The Impact on the Health Sector
In all affected countries the HIV/AIDS epidemic is bringing additional pressure to bear on the health sector. As the epidemic matures, the demand for care for those living with HIV/AIDS rises, as does the toll among health workers. In sub-Saharan Africa, the annual direct medical costs of AIDS (excluding antiretroviral therapy) have been estimated at about US$30 per capita, at a time when overall public health spending is less that US$10 for most African Countries.
Health-care services face different levels of strain, depending on the number of people who seek services, the nature of their need, and the capacity to deliver that care.
The Effect on Hospitals
As HIV infection progresses to AIDS, there is an increase in total hospitalisations. The 2001 Swaziland Human Development Report estimated that people living with HIV/AIDS occupied half of the beds in some health care centres in Swaziland. HIV prevalence among hospitalised patients was almost 33% in one Tanzanian hospital, making HIV infection the major cause of illness leading to hospitalisation. Without major interventions, the problem will worsen. The World Bank estimates that the number of hospital beds needed for AIDS patients could exceed the total number of beds available in Swaziland by 2004 and in Namibia by 20051.
The HIV/AIDS epidemic is also having a negative impact on the overall quality of care provided in hospitals. A shortage of beds, for example, means that people tend to be admitted only at the later stages of illness, reducing their chances of recovery, as some Kenyan hospitals have discovered. Lengthy hospital stays are being reported in Botswana's hospitals, along with staff shortages and staff burnout. Also, more time has to be spent diagnosing cases that are more complex as the epidemic deepens.
Health Care Workers
At the same time as the demand for health services is expanding, so more-health care professionals are being affected by HIV/AIDS. For example, Malawi and Zambia are experiencing a 5-6 fold increase in health worker illness and death rates. Increased workloads and stress might may also spur emigration by health professionals.
The antiretroviral programme in Botswana has faced an acute shortage of trained staff, which has had a significant effect on the programme. There are not enough trained staff to carry out the health checks required for enrolment on the programme, and this has contributed to the enrolment and treatment rates being lower than was first hoped. The problem is compounded by the fact that over 90% of the doctors are foreign and do not speak Setswana, the local language. Another problem faced when recruiting health care staff from abroad is that it takes time for them to become familiar with the local culture.2
Community/Home-Based Care
The emergence of community-bases care programmes, often organised by people living with HIV/AIDS, has become one of the outstanding features of the epidemic. They are also playing a key role in easing the impact. Although many of these programmes are operated by religious groups or non-governmental organisations, the effectiveness of the care does depend on support from formal health, welfare and other social sectors. Also, a study in South Africa has suggested that while home-based care is not cheap it is still an affordable option for the care of people with HIV/AIDS.
The Impact on Households
The toll of HIV/AIDS on households can be very severe. Although no part of the population is unaffected by HIV, it is often the poorest that are the most vulnerable to HIV/AIDS and on whom the consequences are most severe. In many cases, the presence of AIDS means that the household will dissolve, as parents die and children are sent to relatives for care and upbringing. A study in Zambia revealed that 65% of households in which the mother had died had dissolved. But much happens to a family before this dissolution happens: HIV/AIDS strips the family of assets and income-earners, further impoverishing the poor.
Household Income
A study in Côte d' Ivoire revealed that income in affected households was half that of the average household income. This was often the result not only of the loss of income due to illness among household members, but also because other members had to divert more time and effort away from income-generating activities3.
Household Income
A study in three countries, Burkina Faso, Rwanda and Uganda, has calculated that AIDS will not only reverse efforts to reduce poverty, but will increase the percentage of people living in extreme poverty (from 45% in 2000 to 51% in 2015). In Botswana, household income for the poorest quarter of households is expected to fall by 13%. Income earners in these households are also expected to take on an average of four more dependants because of HIV/AIDS.
Basic Necessities
A study in South Africa found that already poor households coping with an AIDS-sick member were reducing spending on necessities even further. The most likely expenses to be cut were clothing (21%), electricity (16%) and other services (9%). Falling incomes forced about 6% of households to reduce the amount they spent on food and almost half of households reported having insufficient food at times.4
"She then led me to the kitchen and showed me empty buckets of food and said they had nothing to eat that day just like other days"4
Food Production
It is estimated that in Burkina Faso, 20% of rural families have reduced their agricultural work or even abandoned their farms because of AIDS. In Ethiopia, AIDS-affected households were found to spend 11-16 hours per week performing agricultural work, compared with an average 33 hours for non-AIDS affected households.
Illness
Taking care of a person sick with AIDS is not only an emotional strain for household members, but also a major strain on household resources. Loss of income, additional care-related expenses, the reduced ability of caregivers to work, and mounting medical fees and funeral expenses together push affected households deeper into poverty. According to the study in Côte d' Ivoire, health care expenses rose by up to 400% when a family member had AIDS.
Funerals
But the financial burden of death can also be considerable, with some families in South Africa spending three times the total household monthly income on a funeral.
How do HIV/AIDS affected Households cope in Africa?
Three main coping strategies appear to be adopted among affected households. Savings are used up or assets sold; assistance is received from other households; and the composition of households tends to change, with fewer adults of prime working age in the households.
Almost invariable, the burden of coping rests on women, as there is an increased demand for their income-earning labour, household work, childcare and care of the sick. As men fall ill, women often have to step into their roles outside the homes. In parts of Zimbabwe, for example, women are moving into the traditionally male-dominated carpentry-industry. This often results in women having less time to prepare food and for other tasks at home.
"I used to stay with the children, but now it is a problem. I have to work in the fields. Last year I had more money to hire labour so the crops got weeded more often. This year I had to do it myself."- Angelina, Zimbabwe-5
Tapping into savings if available and taking on more debt is usually the first option by households that struggle to pay for medical treatment or funeral costs. Then as debts mount, precious assets, such as bicycles, livestock and even land, are sold. Once households are stripped of their productive assets, the chances of them recovering and rebuilding their livelihoods become even slimmer.
The number of working adults in a family will often decrease.
"The first problem with this family is that no one is working. There is no food and no clothes, her mum is not working and there is no father." - Nosipho, South Africa-6
One of the more unfortunate responses to a death in poorer households is removing the children (especially girls) from schools. Often the school uniforms and fees become unaffordable for the families and the child's labour and income-generating potential are required in the household.
"Her brother is sixteen, he is also not in school, he is looking after someone else's cattle for little money. The last born girl has been taken by another pensioner who is not a relative, they see her on holidays."- Nosipho, South Africa-6
The Impact on Children
It is hard to overemphasise the trauma and hardship that children affected by HIV/AIDS are forced to bear worldwide. Not only does HIV/AIDS mean children lose their parents or guardians, but sometimes it means they lose their childhood as well.7
As parents and family members become ill, children take on more responsibility to earn an income, produce food and care for family members. It is harder for these children to access adequate nutrition, basic health care, housing and clothing. Fewer families have the money to send their children to school.
Often both of the parents are HIV-positive in Africa. This has resulted that more children have been orphaned by AIDS in Africa than anywhere else. Also many children will be part of a generation of to be raised by their grandparents or left their own in child-headed households. As projections of the number of AIDS orphans rise, some calls have been heard for an increase in institutional care for children. This solution is not only expensive but also detrimental to the children. Institutionalisation stores up problems for society, which is ill equipped to cope with an influx of young adults who have not been socialised in the community in which they have to live. There are other alternatives available. An example is the approach developed by church groups in Zimbabwe, where they recruit community members to visit orphans in their homes where they live either with foster parents, grandparents, other relatives or in child-headed households.
The way forward is prevention. It is important to prevent children from becoming infected with HIV at birth and later on in their life. Also, generally preventing more people from becoming infected with HIV in the future, and care to prevent people from dying of AIDS is essential. Then fewer children will be orphaned by HIV/AIDS.
The Impact on Education Sector
The extent to which schools and other education institutions are able to continue functioning (as part of the essential infrastructure of societies and communities) will influence how well societies eventually recover from the epidemic.
Fewer Children will Receive a Basic Education
A decline in school enrolment is one of the most visible effects of the epidemic. This will in itself have an effect on HIV prevention, as a good basic education ranks among the most effective and cost-effective means of preventing HIV.8
"'Without education, AIDS will continue its rampant spread. With AIDS out of control, education will be out of reach'" - Peter Piot, Director of UNAIDS9
This reduction in the number of children attending school, will have a significant impact on the ability of many countries to achieve the Education For All targets.10
Why are Fewer Children Attending School in Africa?
Contributing factors include:
The removal of children from school to care for parents and family members
An inability to afford school fees and other expenses AIDS-related infertility and a decline in birth rate, leading to fewer children More children are themselves infected and either do not live long enough to start school or do not survive the years of schooling. For example, research in South Africa showed that the number of pupils enrolling in the first year of primary school in 2001 in parts of KwaZulu-Natal Province, was 20% lower than in 1998. In the Central African Republic and Swaziland, school enrolment is reported to have fallen by 20-36% due to AIDS and orphanhood, with girls being most affected.
"If there is a shortage of money the girl child stays behind and the boy child goes to school. Even if a girl is more intelligent."11
The Impact on Teachers
HIV/AIDS does not only affect pupils but teachers as well. A study in Zimbabwe found that 19% of male teachers and almost 29% of female teachers were infected with HIV. In 2004, it is estimated that 17% of Mozambique's teachers are HIV-positive. This is considerably higher than the national average of 13% HIV prevalence among people aged 15 and 49. It is believed that this will lead to the death of 1.6% per year of the country's teachers.12
Teacher absenteeism is increased by HIV/AIDS as the illness itself causes increasing periods of absence from class. Teachers with sick families also take time off to attend funerals or to care for sick or dying relatives and teacher absenteeism also results from the psychological effect of the epidemic.13
When a teacher falls ill, the class may be taken on by another teacher, may be combined with another class or left untaught. But even when there is a sufficient supply of teachers to replace losses, there can be a significant impact on the students.
"Some of the schools have lost teachers due to this disease. Eventually after a year or two they are replaced with another teacher. But they are not the same as the ones who have died. They cannot teach or do the work as well as the one affected by AIDS. And also the learners, the learners used to know their teachers very well." - School principal, Namibia- 14
The illness or death of teachers is especially devastating in rural areas where schools depend heavily on one or two teachers. Moreover, skilled teachers are not easily replaced. Swaziland has estimated that it will have to train 13,000 teachers over the next 17 years, just to keep services at their 1997 levels - 7000 more than it would have to train if there where no AIDS deaths.
The Impact on Enterprises and Workplaces
HIV/AIDS dramatically affects labour, setting back economic activity and social progress. The vast majority of people living with HIV/AIDS in Africa are between the ages of 15 and 49 - in the prime of their working lives.
AIDS weakens economic activity by squeezing productivity, adding costs, diverting productive resources, and depleting skills. Also, as the impact of HIV/AIDS on households grows more severe, market demand for products and services can fall. The epidemic hits productivity through increased absenteeism. Comparative studies of East African businesses have shown that absenteeism can account for as much as 25-54% of company costs.
A study in several southern African countries has estimated that the combined impact of AIDS-related absenteeism, productivity declines, health-care expenditures, and recruitment and training expenses could cut profits by at least 6-8%. NamWater, Namibia's largest water purification company, has reported that HIV/AIDS was hindering its operation as absenteeism rose and productivity dropped. A study of a sugar mill in South Africa put the cost per worker per year at R9,500 (about £800). Of this, the cost of replacement workers, lost productivity, and absenteeism account for about a quarter each.15
Company costs for health-care, funeral benefits and pension fund commitments are likely to rise unexpectedly as early retirement and deaths rise. A study of a commercial agricultural estate in Kenya showed that AIDS-related medical expenditure exceeded projected expenses by 400%. Funeral costs are also provided by a number of employers in Africa and they are rising sharply.
As HIV/AIDS related costs have risen, so more and more employers have set up HIV/AIDS related programmes at their workplaces. These programmes work more effectively when they also consider the wider realities of the workers' lives. An example is the gold-mining districts in South Africa. The gold mines attract thousands of workers, often from poor and remote regions. Most live in hostels, separated from their families and as a result a thriving sex industry operates around many mines and high HIV prevalence is common. In recent years, mining companies have been working with a number of organisations to implement prevention programmes for the miners. These have included mass distribution of condoms, medical care and treatment for sexually transmitted diseases and awareness campaigns. However, work and social conditions make it difficult to achieve and sustain reductions in HIV and other sexually transmitted infection levels.
In Swaziland, an employers' anti-AIDS coalition has been set up to promote voluntary counselling and testing. The coalition not only includes larger companies but also small and -medium -size enterprises. In Botswana, the Debswana diamond company offers all employees HIV testing, and if they are HIV positive, they and their spouses are offered HIV antiretroviral drugs.16 This policy was introduced in 1999 when the company found that many of their work force were HIV positive. With a skilled workforce, it is financially worth their while to protect the health and therefore the productivity of their workers. They also discovered that retirements due to ill health and AIDS-related deaths had risen markedly. In 1996, 40% of retirements and 37.5% of deaths were due to HIV/AIDS. By 1999, the proportion had risen to 75% and 59% respectively.16
The Impact on Life Expectancy
In many countries of sub-Saharan Africa, AIDS is erasing decades of progress in extending life expectancy. Life expectancy reflects the conditions in a community, but also life expectancy affects conditions in the community. Average life expectancy in sub-Saharan Africa is now 47 years, when it would have been 62 years without AIDS. Life expectancy at birth in Botswana has dropped to a level not seen in Botswana since before 1950. In less than ten years time, many countries in Southern Africa will see life expectancies fall to near 30, levels not seen since the end of the 19th Century.17
Average life expectancy in 11 African Countries (age in years)
Country Before AIDS 2010 Angola 41.3 35.0 Botswana 74.4 26.7 Lesotho 67.2 36.5 Malawi 69.4 36.9 Mozambique 42.5 27.1 Namiba 68.8 33.8 Rwanda 54.7 38.7 South Africa 68.5 36.5 Swaziland 74.6 33.0 Zambia 68.6 34.4 Zimbabwe 71.4 34.6
By 2010, the populations of five countries - Botswana, Mozambique, Lesotho, Swaziland and South Africa will have started to shrink because of the number of people dying from AIDS. In two more countries, Zimbabwe and Namibia, the population growth rate will have slowed almost to zero.

They can't even tell exactly how many people died, let alone died of AIDS, in South Africa. Now you're going to tell me you have the number for all of Africa.
The writer forgot to mention that these are all projections. And projections that are based on assumptions about the wide spread of AIDS.
The same with "life expectancy".

It is widely asserted that teachers are a high-risk behaviour group and that therefore HIV prevalence among the teaching profession is higher than the adult population. No supporting evidence for this assertion is found in the three country studies or any other country in SSA. Teacher mortality in Botswana, for example, was less than half than that projected for the overall adult population in the late 1990s. Mortality rates vary also widely among teachers according to type of school (primary and secondary), gender, location and marital status. In general, mortality rates are much higher among primary school teachers and male teachers. More research is urgently needed to establish the key factors underlying what appear to be very large mortality rate differentials among different groups of teachers.
" Trends in mortality rates have also been investigated. In Uganda, mortality for both primary and secondary school teachers peaked at less than one percent during 1995-97. Probably around half of this mortality was AIDS-related. Both in absolute terms and in relation to high rates of attrition from other causes (resignations, retirements, etc), this level of mortality has not posed a serious threat to the development of the education sector in Uganda. Primary school enrolments expanded over threefold with the introduction of UPE in 1994 and there is currently an excess supply of secondary teachers. The overall mortality rate among teachers in Botswana was around 0.8 percent in 1999/2000. "
In other words, teacher mortality in Uganda and Botswana are well under 1%.
I'm sorry, but this is all bullshit. These are all estimations and projections, based on false assumptions. Not actual counts, like the above account of teachers, or the national censuses in South Africa, Botswana, etc.
The truth is that instead of dying of AIDS, African populations are booming with the highest population growth in the world.
Dying of the new plague, and having a booming population are mutually exclusive.

abinkum@yahoo.com - 27 Apr 2004 00:55 GMT Thanks to the current media debate between Rian Malan and the TAC in South Africa (see my previous post "Aids in AFrica, true or false?"), it has become very clear how meaningless are the computer-modelled figures from scant data in AFrica, upon which all of your brash and unreferenced establishment claims are based. Please provide sources for you information in future, if you want your input to have any credibility.
