HIV-B that targets CD8 cellsThe Body: Rick Sowadsky M.S.P.H., C.D.S, Answers to Safe Sex Questions

Question

Mr. Sowadsky, I heard some information about something referred to as HIV-B which primarily targets CD8 as opposed to CD4 cells. Do you have any knowledge of this? and if so, is this detectable by the standard HIV-1 ELISA? Thank you for your assistance.

Answer

Hi. Thank you for your question.

There are only 2 HIV viruses, HIV-1 and HIV-2. There is no HIV-B virus. Both of the HIV viruses infect CD4 cells (also known as T4 cells or T-Helper cells). More information on HIV-2 can be found in the questions:
