Difference Between HIV 1 and HIV 2

Two HIV virus types exist: HIV-1 is pandemic and aggressive, whereas HIV-2 is confined mainly to West Africa and less pathogenic. Despite the fact that it has been almost 40 years since the discovery of AIDS, there is still no cure or vaccine against HIV.

What is Type 2 HIV?

People with HIV-2 tend to have a lower viral load , or how much of the virus is in their blood, than people with HIV-1. Together with CD4 cell count, which is a way of determining how healthy the immune system is, viral load tells a healthcare provider how well a person's treatment is working.

Why is HIV-2 harder?

It's harder to transmit HIV-2 from person to person, and it takes longer for the infection to turn into AIDS. Both HIV-1 and HIV-2 have multiple groups within them. Those groups branch out even further into subtypes, or strains. HIV constantly makes copies of itself.

What is HIV-1 and HIV-2 test?

There are two types of HIV, called HIV-1 and HIV-2. HIV-1 is the most common type found in the United States, while HIV-2 has a higher prevalence in parts of Africa. HIV tests are used to screen for and diagnose HIV infections.

How common is hiv2?

During 2010–2017, of 327,700 diagnosed HIV infections in the United States, 327,502 (99.94%) were HIV-1. The remaining 198 (0.06%) diagnosed infections were classified as HIV-2 mono-infection (n = 102), dual HIV-1 and HIV-2 infection (n = 11), or probable but unconfirmed HIV-2 infections (n = 85) (Table 1).

What is the normal CD4 count?

A normal CD4 count ranges from 500–1,200 cells/mm3 in adults and teens. In general, a normal CD4 count means that your immune system is not yet significantly affected by HIV infection. A low CD4 count indicates that your immune system has been affected by HIV and/or the disease is progressing.
