WHO Disease Staging System for HIV Infection and Disease in Adults and Adolescents was first produced in 1990 by the World Health Organization [1] and updated in September 2005. It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to ...
The campaign seeks to spread the scientific evidence that undetectable means untransmittable. Since the beginning of the epidemic, perceptions and management of HIV infection have gone through many stages; from assuming the infectiousness, then discovering the routes of transmission (blood, sexual fluids, and breastfeeding), to prevention methods (education, condoms, PrEP, and PEP) and various ...
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.
SARS-CoV-2 and HIV-1 have similarities—notably both are RNA viruses—but there are important differences. As a retrovirus, HIV-1 can insert a copy of its RNA genome into the host's DNA, making total eradication more difficult. [156] The virus is also highly mutable making it a challenge for the adaptive immune system to develop a response.
Education is recognized as a social determinant of health. [1] [2] Education has also been identified as a social vaccine against contracting HIV. [3] Research suggests a negative linear relationship between educational attainment (years of education) and HIV infection rate, especially the educational attainment of women and girls. [4] [5] [6]
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 ...
Counseling focuses on the infection (HIV), the disease , the test, and positive behavior change. VCT has become popular in many parts of Africa as a way for a person to learn their HIV status. VCT centers and counselors often use rapid HIV tests that require a drop of blood or some cells from the inside of one's cheek; the tests are cheap ...
Peer education is an approach to health promotion, in which community members are supported to promote health-enhancing change among their peers. Peer education is the teaching or sharing of health information, values and behavior in educating others who may share similar social backgrounds or life experiences.
