Jump to. Although tests which are sensitive to both types of viruses are widely available, only one antibody test currently available can specifically distinguish between antibodies to HIV-1 or HIV Worldwide, the predominant virus is HIV It is less infectious p huv progresses more slowly than HIV-1, resulting in fewer deaths.
While many commonly used antiretroviral drugs are active against HIV-2, non-nucleoside reverse transcriptase inhibitors NNRTIs like nevirapine and efavirenz do not work against it. The strains of HIV-1 can be classified into four groups. The other three groups - N, O and P - are quite uncommon. All groups can be detected by HIV-1 antibody tests.
Within group M there are known to be at least nine genetically distinct subtypes of HIV Around 89 of these are known to exist. It is very common in the high prevalence countries of Southern Africa, as well as in the horn of Africa and India. The greatest diversity of subtypes is found in Cameroon and the Democratic Republic of Congo - the region where the HIV-1 epidemic originated. But migration and population mixing means geographical patterns in the distribution of subtypes are changing over time, and predicting transmission patterns in particular areas has also become more difficult.
Some studies suggest that certain subtypes have p huv greater risk of transmission or faster disease progression than others — but more recent research suggests that this may not be the case.
A more practical concern are the tests used to diagnose HIV and monitor the level of virus in the body viral load. Tests that are sensitive to the full range of subtypes and to group O and HIV-2 do exist but may not be readily available in all settings.
This is a concern in places where diverse subtypes are prevalent. Can you support us and protect our future?

Like many viruses, HIV has the ability to mutate and change over time - within the main types of HIV there are many genetically distinct subgroups. Tests to diagnose HIV and monitor the level of virus in the body that are sensitive to the full range of subtypes and to group O and HIV-2 do exist, but may not be readily available in all settings. Every contribution helps, no matter how small.
