Since opportunistic infections can cause severe disease, much emphasis is placed on measures to prevent infection. Such a strategy usually includes restoration of the immune system as soon as possible, avoiding exposures to infectious agents, and using antimicrobial medications ("prophylactic medications") directed against specific infections.
Most of these conditions are opportunistic infections that are easily treated in healthy people. The staging system is different for adults and adolescents and children. [2] Stage I: HIV disease is asymptomatic and not categorized as AIDS. Stage II: include minor mucocutaneous manifestations and recurrent upper respiratory tract infections.
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 ...
Additionally, people with AIDS often have systemic symptoms of infection like fevers, sweats (particularly at night), swollen glands, chills, weakness, and weight loss. [13] [14] The specific opportunistic infections that AIDS patients develop depend in part on the prevalence of these infections in the geographic area in which the patient lives.
Following infection with HIV, the rate of clinical disease progression varies enormously between individuals. Many factors such as host susceptibility and immune function, [2] [3] [4] health care and co-infections, [5] [6] [7] as well as factors relating to the viral strain [8] [9] may affect the rate of clinical disease progression.
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. [252]
In 1993, the CDC added pulmonary tuberculosis, recurrent pneumonia, and invasive cervical cancer to the list of clinical conditions in the AIDS surveillance case definition published in 1987 and expanded the AIDS surveillance case definition to include all HIV-infected persons with CD4+ T-lymphocyte counts of less than 200 cells/uL or a CD4 ...
When the CD4 lymphocyte count falls below 200 cells/ml of blood, the HIV host has progressed to AIDS, [1] a condition characterized by deficiency in cell-mediated immunity and the resulting increased susceptibility to opportunistic infections and certain forms of cancer.
