Signs and symptoms of viral hemorrhagic fevers vary by disease. In general, initial symptoms may include:
- High fever
- Muscle, bone or joint aches
Symptoms can become life-threatening
Severe cases of some types of viral hemorrhagic fevers may cause bleeding, but people rarely die of blood loss. Bleeding may occur:
- Under the skin
- In internal organs
- From the mouth, eyes or ears
Other signs and symptoms of severe infections can include:

When to see a doctor
The best time to see a doctor is before you travel to a developing country to ensure you've received any available vaccinations and pre-travel advice for staying healthy.
If you develop signs and symptoms once you return home, consult a doctor, preferably one who focuses on international medicine or infectious diseases. A specialist may be able to recognize and treat your illness faster. Be sure to let your doctor know what areas you've visited.
