Since 1976 there have been 24 KNOWN outbreaks of Ebola. There have been 2,387 KNOWN cases and 1,590 KNOWN deaths. The virus was first intensively studied in Zaire (now the Democratic Republic of Congo). These early outbreaks were restricted to six African countries — Democratic Republic of Congo, Sudan, Gabon, Republic of the Congo, Uganda and the Ivory Coast. The first known outbreak (next blog) was actually near Nazara in what is today South Sudan. It was the SUDV strain of the virus.
At present, we give the impact of the current outbreak in Western Africa with a few cases reported in Spain and the United States. All cases are believed to the EBOV strain, which was what was discovered in Zaire in 1976.
