Ebola hemorrhagic fever outbreaks occurred in 1 975-1 979 and 1994-1996 within tropical Africa. It was determined from Landsat satellite data that all outbreaks occurred in tropical forest with a range of human intrusions. Meteorological satellite data, spanning the 1981 to 2000 time period, showed that marked and sudden climate changes from drier to wetter conditions were associated with the Ebola outbreaks in the 1990s. The extent of the marked climate changes suggest that Ebola outbreaks are possible over large areas of equitorial Africa. Our analysis is limited by only having one Ebola hemorrhagic fever outbreak during our period of study.
