What can be done to control the spread of HIV-2? Human Immunodeficiency Virus Type 2 In3 years after the first reports of a disease that was to become known as AIDS, researchers discovered the primary causative viral agent, the human immunodeficiency virus type 1 HIV Studies of the natural history of HIV-2 are limited, but to date comparisons with HIV-1 show some similarities while suggesting differences.

In persons infected with HIV-2, immunodeficiency seems to develop more slowly and to be milder. As the disease advances, HIV-2 infectiousness seems to increase; however, compared with HIV-1, the duration of this increased infectiousness is shorter.

HIV-2 infections are predominantly found in Africa. Since then, the Centers for Disease Control and Prevention CDC has worked with state and local health departments to collect demographic, clinical, and laboratory data on persons with HIV-2 infection.

Of the 79 infected persons, 66 are black and 51 are male. The region of origin was not known for 15 of the persons, although 4 of them had a malaria -antibody profile consistent with residence in West Africa.

AIDS-defining conditions have developed in 17, and 8 have died. These case counts represent minimal estimates because completeness of reporting has not been assessed. Who should be tested for HIV-2? HIV counseling and test sites or in settings other than blood centers.

Persons at risk for HIV-2 infection include Sex partners of a person from a country where HIV-2 is endemic refer to countries listed earlier Sex partners of a person known to be infected with HIV-2 People who received a blood transfusion or a nonsterile injection in a country where HIV-2 is endemic People who shared needles with a person from a country where HIV-2 is endemic or with a person known to be infected with HIV-2 Children of women who have risk factors for HIV-2 infection or are known to be infected with HIV-2 HIV-2 testing also is indicated for People with an illness that suggests HIV infection such as an HIV-associated opportunistic infection but whose HIV-1 test result is not positive People for whom HIV-1 Western blot exhibits the unusual indeterminate test band pattern of gag p55, p24, or p17 plus pol p66, p51, or p32 in the absence of env gp, gp, or gp41 Continued Among all HIV-infected people, the prevalence of HIV-2 is very low compared with HIV However, the potential risk for HIV-2 infection in some populations such as those listed may justify routine HIV-2 testing for all people for whom HIV-1 testing is warranted.

The decision to implement routine HIV-2 testing requires consideration of the number of HIVinfected persons whose infection would remain undiagnosed without routine HIV-2 testing compared with the problems and costs associated with the implementation of HIV-2 testing.

Antibodies generally become detectable within 3 months of infection. Testing for HIV-2 antibodies is available through private physicians or state and local health departments. Are blood donors tested for HIV-2?

Blood Substitute?

Sinceall U. This testing has demonstrated that HIV-2 infection in blood donors is extremely rare. All donations detected with either HIV-1 or HIV-2 are excluded from any clinical use, and donors are deferred from further donations."They", the health (read disease) industry specialists, check blood better these days to catch unsafe blood supplies contaminated with HIV, hepatitis and other disease components, but blood products still aren't completely safe, even with modern technology.
