Does anyone if you can pass on herpes through donating blood. I've never
heard anyone mention it. Happy Thanksgiving to all you nice folks from
Mississippi...Stan

Hi Stan,

No, you cannot pass it on by giving blood.  The virus lives in the nerve bundles
and not in the blood.

However, you should call your local blood bank just to make sure.

Short, basic answer is no because HSV is not a bloodborne virus. You can
detect it there if you look hard enough (papers often cite PCR methods for
this), but it just doesnt survive unless there is weirdness going on
(always an option with biology). Not to mention that CMV, EBV and other
herpesviruses are bloodborn so they are more likely worried about those
than a weird person who is likely visibly sick anyway - CMV certainly is
something they look for in the UK and I believe the US too.

They will be interested in your HSV status to some extent, but mainly
(as I understand it) to check that you are not actively taking drugs for
it - since they dont want to transfuse a drug into someone of unknown
reactivity (side efffects are rare but no point risking some one having an
allergic reaction for the sake of waiting N days for the donation.

I actually know the answer to this! I called the RI Blood Center and they
told me that you have to be outbreak free for 30 days for herpes. The same
holds true for HPV. Unfortunately that's not the case with me as I still
have an active genital hpv case and frequent herpes outbreaks...oh well...

Thanks, Al.  I think it varies from state to state because the Red Cross website
states that having herpes is no reason to not give blood.  Or something like
that.  Same with HPV.

surgery to my (ex) Monther-in-law who is a wonderful person....how many
people can say that about their mother-in-law Ha!! Have a great
Thanksgiving...Stan

That only makes sense. Especially considering the fact that most
people that have genital herp don't even realize they're infected. And
there's no telling how many people that realize they have fever
blisters and don't know that *that's* herpes.

Thats not really due to worries that you can pass the virus on in
donation. Thats a general thing for infections of any kind (hence the
common are you in good health today question). Any infection starts a
whole series of chemicals sloshing round your body via the blood at levels
that will have the potential to kick off reactions they do not want in
patients getting transfusions

Well the funny thing is that I asked them if taking Valtrex was okay for
giving blood and they said it was okay. I guess its probably a general rule
then, because most people who have genital herpes don't even know it, I was
one of them for a long time.

A 'No current infection' is usually, fairly easy to screen even at the
level of common cold - its (as I understand it) the immune system
responses which if you were to transfuse into say a transplant patient
might kick off all sorts which would be a potential problem...

Im quite surprised about the Valtrex one, most people who have asked and
reported that they've been told that medications tend to drop blood out of
the system - I think you are the first to have been told otherwise and
mention that here from memory...
