Summary

Between 1888 and 1897, rinderpest virus (cattle plague) spread throughout sub-Saharan Africa, presumably for the first time, killing over 90 percent of African cattle and countless wildlife, expedited by European colonial conquest. Beginning in the Eritrean port of Massawa, the virus was transmitted across the Sahel, reaching the Senegal River by 1891. The epizootic spread south out of the Horn of Africa, into the western and eastern Rift valleys, and likely by sea with coastal commerce, infecting East Africa after 1891. Although slowed by the Zambezi River, in 1896 rinderpest reached the regions of modern Zimbabwe, Mozambique, Botswana, South Africa, Namibia, and southern Angola before it burned out or was arrested by breakthroughs in vaccine therapy by 1900. South of the Zambezi, early European methods of stanching rinderpest by destroying all cattle exposed to the virus often elicited protest, resistance, and sometimes rebellion. Rinderpest was eliminated from southern Africa shortly after the turn of the 20th century but became enzootic in other parts of the continent, often in wildlife, until eradicated globally in 2011. In each region of infection, local ecologies, trade patterns, agricultural bases, social structures, and power dynamics shaped the impact of rinderpest. Almost everywhere, rinderpest was preceded by drought and locust plagues, and followed by human diseases, especially smallpox and malnutrition.
