Africa continues to be the most affected continent by HIV/AIDS. The continent accounts for over 70% of HIV/AIDS infections in the world with around 23 million people infected with the virus. Although the reported number of new infection was highest during the 1990s, the disease continues to be a big challenge to the development of many African nations. From country to country, the epidemic varies across the continent, with the estimates of prevalence ranging from 0.1% in Madagascar and as high as 15% in some countries in the south of Africa. Death resulting from the disease has been on the decline with the introduction of antiretroviral therapy (ART) and PMTCT coverage increase. The impact of the disease on the continent varies from country to country, depending on the size and duration since the first reported case. In most countries, there is a generalized epidemic, where we have in some countries the adult prevalence exceeding 20% in various countries. For example, according to Joint United Nations Program on HIV/AIDS (UNAIDS); the adult prevalence in Botswana is 24.8%, Lesotho (23.6 percent), and Swaziland (25.9 percent). Other countries have concentrated epidemics, with the disease affecting various hotspots. For example, the prevalence in Burundi is 38% among the sex workers, which is 16 times more than the prevalence among the adult population. The general prevalence in West Africa is low compared to that in East and Southern Africa, although the epidemic among the MARPs (Most at risk population) is common(UNDP, 2010).
