Hiv-2

HIV-2 is a type of human immunodeficiency virus (HIV) which can cause AIDS. It is much less common than HIV-1 and is mainly found in West Africa. It is estimated that between 1-4% of all HIV infections are due to HIV-2. Unlike HIV-1, HIV-2 is believed to be less aggressive and progresses more slowly in those infected. This means that those with HIV-2 have a better prognosis than those infected with HIV-1. Treatment usually consists of drug combinations similar to those used for HIV-1. However, due to its lesser prevalence, HIV-2 is often not tested for, leading to delays in diagnosis and treatment. It is important for people to understand the differences between HIV-1 and HIV-2 and also to be aware of the prevalence of HIV-2 in West Africa.
