Antiretroviral medicines can help lan! d the amount of virus in the body, preserve CD4+ T cells and dramatically slow the devastation of the immune system. Normal T-cells. HIV-infected T-cells. People who are not infected with HIV and generally are in good health drive roughly 800 to 1,200 CD4+ T cells per three-d millimeter (mm3) of blood. both(prenominal) people who have been diagnosed with AIDS have fewer than 50 CD4+ T cells in their entire body. HIV is a virus most commonly caught by having naked sex or by sharing infected needles to come in drugs.
