Document Summary

Characterized by severe damage to the immune system. An important clue was the development of a lung infection (pneumonia) caused by a fungus called pneumocystis in aids patients. Patients undergoing chemotherapy for immune system cancers (lymphomas) also got this infection. Hiv the pathogen that can infect humans and leads to aids: pathogen a microorganism that causes disease. Hiv positive antibody to hiv is detected in blood: infected with hiv -> hiv is present in the body. Syndrome set of signs and symptoms that occur together during a particular type of illness. Aids develops as the result of infection by hiv due to hiv-induced destruction of parts of the immune system: this cannot function normally to kill or control pathogens or cancer cells. First stage of hiv is asymptomatic, but individual is able to transmit disease. Second stage, the hiv incubation period is of variable duration, on average 10 years or more.
