At this point, seroconversion, the development of antibodies, occurs and the CD4 T cell counts begin to recover as the immune system attempts to fight the virus, marking the HIV set point. The higher the viral load at the set point, the faster the virus will progress to AIDS; the lower the viral load at the set point, the longer the patient ...
Prevalence of AIDS in Nigeria from 1991 to 2010. Includes predictions up to 2018. [1] HIV/AIDS in Nigeria was a concern in the 2000s, when an estimated seven million people had HIV/AIDS.

HIV/AIDS can be transmitted sexually, via contaminated needles or blood transfusions, and from mother to child during pregnancy, birth or breast-feeding. Contents Top
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.
An HIV vaccine is a potential vaccine that could be either a preventive vaccine or a therapeutic vaccine, which means it would either protect individuals from being infected with HIV or treat HIV-infected individuals. It is thought that an HIV vaccine could either induce an immune response against HIV (active vaccination approach) or consist of ...
It follows UNICEF UK’s ‘Born Free from HIV’ campaign, which concentrated on the issue of preventing mother-to-child transmission of HIV. [5] In 2008, it was estimated that young people aged 15 to 24 accounted for an estimated 45 per cent of new HIV infections worldwide and that almost two young people acquire HIV every minute.
Prevalence of HIV/AIDS in Africa, total (% of population ages 15–49), in 2021 (World Bank) HIV / AIDS originated in the early 20th century and remains a significant public health challenge, particularly in Africa. Although the continent constitutes about 17% of the world's population, it bears a disproportionate burden of the epidemic. As of 2023, around 25.6 million people in sub-Saharan ...
