Key points
- 1
Ebola disease is a rare but severe viral illness caused by viruses in the Orthoebolavirus genus. Several distinct viruses can cause human disease, including Ebola virus, Sudan virus and Bundibugyo virus. Symptoms overlap with other infections, so symptoms alone cannot confirm Ebola.
- 2
Rapid public-health notification, exposure assessment, infection prevention and control, and safe referral to designated services.
- 3
Contact public-health services promptly after a credible exposure, even if there are no symptoms.

What is Ebola Disease: Symptoms, Transmission, Prevention and Treatment?
Ebola disease is a rare but severe viral illness caused by viruses in the Orthoebolavirus genus. Several distinct viruses can cause human disease, including Ebola virus, Sudan virus and Bundibugyo virus. Symptoms overlap with other infections, so symptoms alone cannot confirm Ebola.
The incubation period—the time from infection to the start of symptoms—is 2 to 21 days. People are generally considered infectious after symptoms begin; public-health authorities determine exposure monitoring and appropriate precautions.
Early symptoms may include sudden fever, fatigue, weakness, headache, muscle pain and sore throat. Other symptoms can include vomiting, diarrhoea, abdominal pain and rash. Bleeding can occur but is not present in every case and should not be required before Ebola is considered.
Ebola is not spread through the air like measles. Transmission occurs through direct contact, through broken skin or the eyes, nose or mouth, with blood or other body fluids of a person who is sick with or has died from the disease, or with objects contaminated by those fluids. Contact with infected animals may also transmit infection.

Clinical context
Clinical and public-health note
Ebola is a high-consequence infectious disease. Assessment, isolation, testing, transport and specimen handling must be coordinated by trained personnel under current national protocols. Do not attempt home diagnosis, home isolation arrangements without public-health direction, or unprotected examination of a suspected case.
Ebola disease: key facts
| Topic | Key information |
|---|
| Incubation | 2–21 days after exposure | ACT |
| Transmission | Direct contact with infectious blood/body fluids or contaminated objects; some animal exposures | CHECK |
| Diagnosis | Laboratory confirmation arranged by public-health and specialist teams | ACT |
| Treatment | Early specialist supportive care improves outcomes; approved specific treatments depend on the virus species | CHECK |

When to seek urgent advice
- 1Contact public-health services promptly after a credible exposure, even if there are no symptoms.
- 2If fever or other compatible symptoms develop within 21 days after a possible exposure, avoid close contact and telephone healthcare/public-health services before attending in person.
- 3Do not rely on symptoms alone to distinguish Ebola from malaria, typhoid, Lassa fever or other infections; clinicians and public-health teams will advise on safe assessment and testing.
04 · Prevent & manage
Practical steps
Do not manage suspected Ebola at home without public-health direction
Do not touch a person’s blood or body fluids, contaminated clothing or bedding, or the body of someone who may have died from Ebola. Do not use unprotected care, share unverified claims, or stigmatise people who are ill or recovering.
- 1Follow official instructionsIf identified as a contact, cooperate with the public-health team and follow the prescribed monitoring period, commonly 21 days after the last exposure.
- 2Use routine hygieneWash hands with soap and water or use an appropriate alcohol-based hand rub. Avoid contact with body fluids and contaminated materials.
- 3Protect othersIf symptoms occur after a possible exposure, telephone services first, explain the exposure and travel history, and follow instructions for safe transport and assessment.
- 4Use trusted informationConsult WHO and the Nigeria Centre for Disease Control and Prevention (NCDC) for current guidance. Outbreak status and response measures can change.
