Subtypes of Hiv
Human immunodeficiency virus (HIV) is a virus that weakens the body’s ability to fight off infections and illnesses. It is a leading cause of death and disability worldwide. HIV has two main subtypes, HIV-1 and HIV-2. HIV-1 is the most common and predominant form and is mainly found in the Americas, Europe, and Japan. HIV-2 is predominantly found in West Africa. Studies have shown that HIV-2 is less infectious and progresses slower than HIV-1. Subtypes of HIV are important to understand as they affect the way HIV is diagnosed, treated, and managed. HIV testing looks for the virus or antibodies to it, and the type of HIV will determine how the test should be done. Different medications are used to treat different subtypes, and should be tailored to the subtype of HIV the patient has. Knowing the subtype of HIV also helps to prevent transmission of the virus between individuals.
