Pneumocystis infection can also be diagnosed by immunofluorescent or histochemical staining of the specimen, and more recently by molecular analysis of polymerase chain reaction products comparing DNA samples. Notably, simple molecular detection of P. jirovecii in lung fluids does not mean that a person has PCP or infection by HIV.
Pneumocystosis is a fungal infection that most often presents as Pneumocystis pneumonia in people with HIV/AIDS or poor immunity. [1] [7] It usually causes cough, difficulty breathing and fever, and can lead to respiratory failure. [4]
The latency stage involves few or no symptoms and can last anywhere from two weeks to twenty years or more, depending on the individual. AIDS, the final stage of HIV infection, is defined by low CD4+ T cell counts (fewer than 200 per μL), various opportunistic infections, cancers, and other conditions.

A child is defined as someone under the age of 15. This staging system also requires the presence of HIV infection: HIV antibody for children aged 18 months or more; virological or p24 antigen positive test if aged under 18 months.
In 1993, the CDC added pulmonary tuberculosis, recurrent pneumonia and invasive cervical cancer [2] to the list of clinical conditions in the AIDS surveillance case definition published in 1987 [3] and expanded the AIDS surveillance case definition to include all HIV-infected persons with CD4+ T-lymphocyte counts of fewer than 200 cells/μL or ...
As the Times points out, a monetary donation wouldn't go amiss toward earning an indulgence. It writes, "charitable contributions, combined with other acts, can help you earn one."
Although there was known to have been at least one case of AIDS in the U.S. from 1966, [269] the vast majority of infections occurring outside sub-Saharan Africa (including the U.S.) can be traced back to a single unknown individual who became infected with HIV in Haiti and brought the infection to the U.S. at some time around 1969.
