Human Immunodeficiency Virus has claimed the lives of more than 25 million people since 1981. HIV gets to the immune system by infecting important cells, including helper cells called CD4+ T cells, plus macrophanges and dendritic cells. Once the virus has taken hold, it systematically kills these cells, damaging the infected person’s immunity and leaving them more at risk from infections. The majority of people infected with HIV go on to develop AIDS. Once a patient has AIDS common infections and tumours normally controlled by the CD4+ T cells start to affect the person.
In the latter stages of the disease, pneumonia and various types of herpes can infect the patient and cause death.l< << PREV 1 of 13 NEXT >>
