HIV-1 is the most common and most pathogenic strain of the virus. As of 2022, approximately 1.3 million such infections occur annually. [4] [5] Scientists divide HIV-1 into a major group (group M) and two or more minor groups, namely groups N, O and possibly a group P.
HIV can also disseminate by direct transmission from one cell to another by a process of cell-to-cell spread. [96] [97] The hybrid spreading mechanisms of HIV contribute to the virus' ongoing replication against antiretroviral therapies. [95] [98] Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was originally ...

The genome and proteins of HIV (human immunodeficiency virus) have been the subject of extensive research since the discovery of the virus in 1983. [1] [2] "In the search for the causative agent, it was initially believed that the virus was a form of the Human T-cell leukemia virus (HTLV), which was known at the time to affect the human immune system and cause certain leukemias.

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 ...
