Transmission rates

[Zhadi]

Hello,

Another question - I have read that female to male transmission from vaginal intercourse is anywhere from 1 in 1000 to 1 in 10,000. But does this apply to all strains of HIV? Is there any research on whether different strains are easier to transmit?

Also, does anyone know when the expert forum will be back up?

Thanks

I never said there are no strains of HIV. All I want to say is the mode of transmission/infection for all those strains is the same.

But there ARE different strains, with A, B, C tags. Look up HiV subtypes on Wikiedia

I dont have any links to prove anything, its just common sense :). If HIV infection would have been dependent on strains of virus, then the infection would have been refered to as HIV-Strain A..HIV -Strain B and the exposures and conditions would differ too. You need not read any link for this. Its plain common logic :)

Thanks Nichkin. Do you have a link that confirms this?

Infection doesnt depend on the strains of virus.

Thanks, but that's not really what I was asking. My question was whether the 1in 1000 applies to all strains of HIV or are some more easily transmitted than others.

Thanks

Hi,

The above doesnt mean that single exposure wont lead to an infection. That is stated over all in general observation as HIV is a fragile virus to get transmitted via penis-vaginal intercourse in single go. Its diffucult not impossible.

No one knows?
