Ebola virus

Ebola virus was first identified as a filovirus in 1976, following epidemics of severe haemorrhagic fever in sub-Saharan Africa. Further outbreaks have occurred since, but, despite extensive and continued investigations, the natural reservoir for the virus remains unknown. The mortality rate is high and there is no cure for Ebola virus infection. Molecular technology is proving useful in extending our knowledge of the virus. Identification of the host reservoir, control and prevention of further outbreaks, rapid diagnosis of infection, and vaccine development remain areas of continued interest in the fight against this biosafety level-four pathogen.
