HIV2 in Chicago?
Apr 26, 2001

I've had negative ELISA and Amplicor PCR-DNA at 5 months after an encounter. (No West Africans were directly involved.) The ELISA and PCR-DNA were for HIV1. 2 questions: 1)Can I stop worrying about HIV1? 2)Should I be concerned about HIV2?

Response from Mr. Kull

HIV-2 is not prevalent in the United States, so it is highly unlikely that you would have been exposed to HIV-2. HIV-2 is endemic in West African countries. HIV-2 screening is recommended for West African residents, their sex partners, and those receiving blood donations in that area.

A negative HIV-1 test at five months is a highly definitive result (see response to "Definite Exposure" http://www.thebody.com/Forums/AIDS/SafeSex/Archive/Testing/Q11060.qna). HIV-1 antibody tests, while not totally reliable in detecting HIV-2 infection, will detect HIV-2 anitbodies about 70% of the time.
