The human immunodeficiency virus (HIV) [8] [9] [10] is a retrovirus [11] that attacks the immune system.It is a preventable disease. [5] There is no vaccine or cure for HIV. It can be managed with treatment and become a manageable chronic health condition. [5]
HIV is commonly transmitted via unprotected sexual activity, blood transfusions, hypodermic needles, and from mother to child. Upon acquisition of the virus, the virus replicates inside and kills T helper cells , which are required for almost all adaptive immune responses .
The latest recommendations of the US Centers for Disease Control and Prevention (CDC) show that HIV testing must start with an immunoassay combination test for HIV-1 and HIV-2 antibodies and p24 antigen. A negative result rules out HIV exposure, while a positive one must be followed by an HIV-1/2 antibody differentiation immunoassay to detect ...
Lentivirus is a genus of retroviruses that cause chronic and deadly diseases characterized by long incubation periods, in humans and other mammalian species. [2] The genus includes the human immunodeficiency virus (HIV), which causes AIDS.
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.
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.

This test also detects a protein called p24 in maternal blood, which is a specific component of the HIV virus itself and also acts as an early marker of an HIV infection. If this test is positive, the CDC recommends performing follow-up testing using a test called the HIV-1/HIV-2 antibody differentiation immunoassay that both confirms the ...
