You need to transmit a certain amount of HIV particles to cause infection. It is called inoculum. In normal sex, it is quite a lot, I wasn't able to find an exact number, but it is in tens of thousands in ther least. The vast majority of virions seems to be killed by the immune system before they can actually take hold. https://journals.plos.org/plospathogens/article?id=10.1371/j... |
