Relative to HIV-1, HIV-2 is less virulent and is characterized by lower plasma HIV RNA levels, slower decline in CD4 cell counts, lower AIDS-related mortality rates, lower rates of perinatal transmission, and lower rates of sexual transmission.[2,6,11,15,16,17] For example, in West Africa, investigators prospectively followed 133

HIV-1, which was discovered first, is the most widespread type worldwide. HIV-2 is more than 55% genetically different from HIV-1. HIV-2 is most common in western Africa and is becoming more common in India, although numbers there are still relatively small.

HIV-1 and HIV-2 are the two main types of the HIV virus. Most people living with HIV have HIV-1. Both types of HIV weaken the immune system, but HIV-2 tends develop more slowly and is less easy for The difference between HIV-1 and HIV-2 are as follows HIV-1 is the most common type of HIV and accounts for 95% of all infections, whereas HIV-2 is relatively uncommon and less infectious.

Among specimens confirmed to have HIV infection (true positives), Multispot and Western blot detected HIV-1 antibody in a similar proportion of cases (93.7% vs. 94.4% respectively) while Multispot and IFA also detected HIV-1 antibody in a similar proportion of cases (84.5% vs. 83.4% respectively).

All were negative. Exposure was body to body massage ,hand Although HIV-1 infection is associated with most of the global AIDS pandemic, HIV-2 is an important cause of disease in West Africa, where it is endemic . HIV-2 infection is also found in areas with cultural and socio-economic ties to West Africa, including the United States. Before the 4th-generation HIV-1/2 Ag/Ab and HIV-1/2 Ab differentiation immunoassays for HIV testing became widely available, clinicians suspected chronic HIV-2 infection in certain clinical scenarios, such as a declining CD4 cell count in an HIV-1–seropositive, untreated individual with an undetectable HIV-1 plasma viral load, or an opportunistic infection in an individual from West Africa Comparing HIV-1 and HIV-2 infection: Lessons for viral immunopathogenesis. Nyamweya S(1 whereas HIV-1 extends worldwide. Clinically, HIV-2 HIV-2 was more similar to the then-known SIV strains than to HIV-1, suggesting for the first time the simian origin of HIV. Further studies indicated that HIV-2 is derived from the SIVsmm strain found in sooty mangabeys, whereas HIV-1, the predominant virus found in humans, is derived from SIV strains infecting chimpanzees (SIVcpz).
