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 .
HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells. [88] HIV is a member of the genus Lentivirus, [89] part of the family Retroviridae. [90] Lentiviruses share many morphological and biological characteristics.
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower ...
HIV testing is an essential gateway to HIV prevention, treatment, care and support services. [31] It is crucial to have HIV tests available for individuals worldwide since it can help individuals detect the status of their disease from an early onset, seek help, and prevent further spread through the practice of suggestive safety precautions.
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.
The most updated HIV testing protocols recommend using the HIV-1 and HIV-2 antigen/antibody combination immunoassay as the initial screening test for an HIV infection. [22] This blood test assesses whether or not the mother has created antibodies , which are disease-fighting proteins of the immune system, against the HIV-1 and HIV-2 viruses.
Discrimination against people with HIV/AIDS or serophobia is the prejudice, fear, rejection, and stigmatization of people with HIV/AIDS (PLHIV people living with HIV/AIDS). Marginalized, at-risk groups such as members of the LGBTQ+ community, intravenous drug users, and sex workers are most vulnerable to facing HIV/AIDS discrimination.
