Plz with health what is the history of ebola? (include first known cases, current rate and risk of infection, and outbreak events)

Ebola was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of the Congo. Since then, outbreaks have appeared sporadically in Africa , Although some holding centers tried to separate suspect patients based on wet (diarrhea or vomiting) versus dry symptoms, this crude separation can expose Ebola-negative patients, particularly those with wet symptoms, to a higher risk of nosocomial infection.
