HIV-1 enters the immune system by attaching onto the CD4+ receptor found on the surface of certain white blood cells. HIV-2 has a harder time gaining such a foothold. So HIV-2 generally progresses much more slowly, with lower viral laod and slower risk of becoming sick. However, some HIV drugs (including NNRTIs) are not active against HIV-2.

Discussion. These results are consistent with the previously reported findings from 1987–2009 that HIV-2 remains a rare diagnosis in the United States (5).Use of the HIV-1/HIV-2 differentiation test increased steadily throughout the study period, although after 2014 the number of confirmed or probable HIV-2 infections remained stable. The human immunodeficiency virus is classified into two main types: HIV-1 and HIV-2. HIV-1 was discovered first and is more prevalent worldwide, while HIV-2 is less pathogenic and is mostly HIV-2 is mainly seen in a few West African countries.
