  • Multidisciplinary teams have been deployed to the field to actively search and manage cases; trace and follow-up contacts; and to sensitize communities on the outbreak prevention and control.

  • The Ebola virus causes severe Ebola Virus disease (EVD) outbreaks in humans.

  • Ebola Virus disease outbreaks have a case fatality rate of up to 90%.

  • Ebola Virus disease outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests.

  • The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.

  • Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.

  • There is no treatment or vaccine available for either people or animals.

  • The incubation period (interval from infection to onset of symptoms) varies between 2 to 21 days.

  • EVD is a severe acute viral illness often characterized by the sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is followed by vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding.
