Signs and symptoms of viral hemorrhagic fevers vary by disease. In general, initial symptoms may include:

  • High fever
  • Fatigue
  • Dizziness
  • Muscle, bone or joint aches
  • Weakness

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:

  • Shock
  • Nervous system malfunctions
  • Coma
  • Delirium
  • Kidney failure
  • Liver failure

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.
