  • On May 9, 1995, the city of Kinshasa was placed under quarantine after an outbreak of the deadly Ebola virus. Kinshasa was the capital of Zaire (now the Democratic Republic of the Congo), and the quarantine was enacted by the Zairean government. Thousands of people tried to leave this “hot spot” and were met by military roadblocks. The government also declared quarantine for the city of Kikwit, where the virus had been detected two months earlier.
    Ebola is an infectious disease usually characterized by fever and flu-like symptoms. After these initial symptoms, there is often diarrhea, vomiting, rashes, and heavy bleeding. Ebola is usually transmitted by contact with an infected person, corpse, or contaminated material. There is no known source for this deadly virus, and there is no official treatment or vaccine.
    Outbreaks of Ebola have been found in gorillas, chimpanzees, pigs, and humans. In humans, the virus causes death in 50 to 90 percent of the cases. The outbreak in Kikwit had a 77% fatality rate.
