| Response from Mr. Kull
 Because HIV is not transmitted that easily!!! In order for there to be a risk of transmission HIV infected fluids (like blood, semen, and vaginal secretions) need to have direct access to an uninfected person's mucous membranes or bloodstream. This needs to occur relatively soon after the fluids leave the person's body, because HIV does not survive in the environment long. But that's not all: there are many other factors, observable or not, that will influence the likelihood of transmission. The viral load of the host, the volume of fluid, the immune response of the uninfected person, the presence of STIs, etc. Stick to the facts: people are not known to be infected through kissing or casual contact.
