HIV+ prostitute has check-up. East African woman, Feliciana aged 28, has lymph glands in her neck examined by a doctor at Majengo clinic. As an HIV positive prostitute, she is part of a group selected for a study into AIDS (Acquired Immune Deficiency Syndrome). Although she carries the HIV virus which causes AIDS, she has no symptoms which suggest that her immune system is impaired. The study involves treatment for HIV, as well as monitoring the blood and related diseases. Up to 10% of prostitutes from this area are HIV resistant and have no viral antigen in their blood, although they have been exposed to the HIV virus. Photographed at Pumwani in Nairobi, Kenya.
