Ebola Virus Disease

Overview of Ebola Virus Disease

Ebola virus disease, or Ebola hemorrhagic fever, is a severe illness that occurs in humans and non-human primates and can often be fatal. This disease is caused by the Ebola virus of the Filoviridae family. It was first seen in 1976 in both the Democratic Republic of Congo and in Sudan. More recently, an outbreak has originated from West Africa, and is one of the largest Ebola outbreaks in history. It is not currently an imminent threat to the United States.

Signs & Symptoms

Signs and symptoms usually occur 8-10 days after being infected by the Ebola virus, but can appear as early as 2 days or as late as 21 days later. Typical signs and symptoms of Ebola include:

  • Fever higher than 38.6° C or 101.5° Fahrenheit
  • Severe headaches
  • Intense weakness
  • Muscle pain
  • Sore throat
  • Diarrhea
  • Vomiting
  • Abdominal pain
  • Loss of appetite
  • Rashes
  • Internal and/or external bleeding


Ebola is transmitted through direct contact with infected blood, secretions, or other bodily fluids, including urine, saliva, feces, vomit, and semen. Always remember to practice good hygiene habits, such as regular hand washing and avoiding contact with blood and bodily fluids. To prevent further transmission, avoid close contact with anyone who is infected or may be infected with the virus.

Seek professional clinical help if you have any of the signs and symptoms above and have had exposure to a person known or suspected to have ebola or if you have resided in or have recently traveled to an area where ebola is active. The sooner you seek help, the higher your chances of recovery will be.

There is currently no vaccine for Ebola, so it is extremely important to take the necessary precautions to prevent further transmission of Ebola.
