The [[climate of Africa]] lends itself to certain environmental diseases, the most serious of which are: [[malaria]], [[African trypanosomiasis|sleeping sickness]] and [[yellow fever]]. Malaria is the most deadly environmental disease in Africa. It is transmitted by a genus of mosquito ([[anopheles mosquito]]) native to Africa, and can be contracted over and over again. There is not yet a vaccine for malaria, which makes it difficult to prevent the disease from spreading in Africa. Recently, the dissemination of mosquito netting has helped lower the rate of malaria.

Yellow fever is a disease also transmitted by mosquitoes native to Africa. Unlike malaria, it cannot be contracted more than once. Like chicken pox, it is a disease that tends to be severe the later in life a person contracts the disease.<ref name= "Africa geography"/>

Sleeping sickness, or African trypanosomiasis, is a disease that usually affects animals, but has been known to be fatal to some humans as well. It is transmitted by the [[tsetse fly]] and is found almost exclusively in Sub-Saharan Africa.<ref>{{cite web| title= Human African trypanosomiasis (sleeping sickness)| work= World Health Organization| url=https://www.who.int/mediacentre/factsheets/fs259/en/| access-date= May 4, 2012}}</ref> This disease has had a significant impact on African development not because of its deadly nature, like Malaria, but because it has prevented Africans from pursuing agriculture (as the sleeping sickness would kill their livestock).<ref name= "Africa geography"/>
