More than a dozen strains of simian immunodeficiency virus. HIV is a type of virus known as a retrovirus.

His key contribution came at a time when AIDS was mysterious and uniformly deadly. Certain opportunistic infections involving bacteria viruses.

A good CD8 T cell response has been linked to slower disease progression and a better prognosis though it does not eliminate the virus. HIV infection is caused by exposure to the human immunodeficiency virus. HIV is a virus that damages the immune system.

Immune function is typically measured by CD4 cell count. AIDS is an acquired immuno- deficiency syndrome that causes a reduction in helper T cells by the infection caused by the virus and affects the immune system.
