Ebola virus disease (EVD) is a severe, often fatal illness caused by viruses of the Filoviridae family. First identified in 1976 in what is now the Democratic Republic of Congo, Ebola has caused multiple large outbreaks in Central and West Africa. Understanding transmission, symptoms, and appropriate precautions is important for anyone travelling to affected regions or following a declared outbreak in the news.
How Ebola Spreads
Ebola does not spread through the air, water, food, or casual contact. The virus transmits through direct contact with the blood, body fluids (saliva, urine, faeces, vomit, breast milk, semen, or sweat), or organs of a person who is sick with or has died from Ebola. Healthcare workers and family caregivers who have close contact with infected patients without full personal protective equipment face the highest risk. Fruit bats are believed to be the natural reservoir host; contact with wild animals (hunting, handling, eating bush meat) has been associated with index cases in outbreaks.
Recognising Symptoms
Symptoms appear two to twenty-one days after exposure (average eight to ten days), and begin with:
- Sudden high , , and severe
- Muscle pain and sore throat
- Vomiting, diarrhoea, and abdominal pain
- Rash, impaired kidney and liver function
- In severe cases, internal and external
Clinical guidance from CDC[1] stresses matching home care to symptom severity and seeking urgent review when red-flag signs appear.
Treatment and Supportive Care
Two monoclonal antibody treatments — REGN-EB3 (Inmazeb) and mAb114 (Ebanga) — have received approval for the Zaire Ebola species and significantly improve survival when given early. Supportive care remains essential and includes oral and intravenous rehydration, management, and treatment of secondary infections. An effective vaccine (rVSV-ZEBOV, Ervebo) is now available and has been used in outbreak response in Africa.
Precautions for Travellers
- Check current outbreak status at your national health authority or the WHO Disease Outbreak News before travel to Central or West Africa.
- Avoid contact with the blood or body fluids of any sick person.
- Avoid handling wild animals, bush meat, or bats.
- Wash hands frequently with soap and water or alcohol-based hand sanitiser.
- If you develop within 21 days of returning from an outbreak area, call ahead to your healthcare facility before arriving — do not simply walk in.

Home Isolation Is Not Appropriate for Suspected Ebola
Unlike many other viral illnesses, suspected Ebola requires immediate medical evaluation and isolation in a designated infectious disease facility. Do not attempt to manage suspected Ebola at home. Contact health authorities by telephone for guidance on how to present safely.

When home care is not enough: chest pain, trouble breathing, confusion, or symptoms that worsen quickly need urgent medical attention.
