Are there 2 types of HIV?
There are two types of HIV, HIV-1 and HIV-2, as well as several related viruses that infect certain monkeys or great apes. HIV-1 can be found throughout the world, but HIV-2 is almost exclusively limited to West Africa. HIV-1 is transmitted more easily than HIV-2, and HIV-1 infection progresses more rapidly to AIDS.
What is the difference between HIV type 1 and type 2?
Compared to HIV-1, HIV-2 infection is characterized by a much longer asymptomatic stage, lower plasma viral load, slower decline in CD4+ T-cell count, and lower mortality rate attributable to AIDS (11, 14, 19, 28, 36).
What are the two main strain of HIV?

How does superinfection affect HIV?from healthline.com
Superinfection can impact HIV treatment. This is because the new virus may be resistant to the antiretroviral drugs that a person is currently taking.
How many HIV strains are there?from healthline.com
The Centers for Disease Control and Prevention (CDC) estimates that 1.2 million.
Why is it important to know if you have HIV-1 or 2?from healthline.com
This is because treatment of HIV-2 can be different than HIV-1, as HIV-2 viruses are resistant to some types of antiretroviral drugs.
Why is it important to get tested for HIV?from healthline.com
Getting tested for HIV is important after a potential exposure. It’s also recommended for people that may be at a higher risk for contracting the virus. Antiretroviral medications can be used to effectively reduce virus to undetectable levels.
What is it called when a virus is replaced by another virus?from healthline.com
This is called superinfection. When superinfection occurs, the new strain can either replace or coexist in the body along with the original strain. The exact prevalence of HIV superinfection is unknown, and estimates can vary based on individual studies.
