Man with syphilis in German East Africa, c. early 1900s. Syphilis, a sexually transmitted infection, is a major danger to public health, particularly in developing countries, including those in sub-Saharan Africa. The disease, whose origin is contested amongst researchers, arrived in Africa no later than the 16th century. Since then, it has ...
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 ...
According to a graph done by UNAIDS, there were 4 200 000 people living with HIV in South Africa in 2005. This was an increase of 400 000 people since 2003. [50] As of 2018, the prevalence of HIV in Eastern and Southern Africa combined was 1.8 million. This number only represents children and adolescents (Ages 0–19).
Rates of congenital syphilis have decreased between the 1980 and 2000s due to better access to prenatal care. [16] A five-year study among 250 patients in each year among attendees in an STI clinic in West Bengal found significantly decreased(p<0.05) Syphilis prevalence from 10.8% (in 2004) to 3.6% (in 2008).

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 ...
The discovery of the main HIV/SIV phylogenetic relationships permits explaining broad HIV biogeography: the early centres of the HIV-1 groups were in Central Africa, where the primate reservoirs of the related SIVcpz and SIVgor viruses (chimpanzees and gorillas) exist; similarly, the HIV-2 groups had their centres in West Africa, where sooty ...
