By Mayo Clinic staffBoth Ebola and Marburg hemorrhagic fevers lead to death for a high percentage of people who are affected. As the illness progresses, it can cause:
- Multiple organ failure
- Severe bleeding
- Jaundice
- Delirium
- Seizures
- Coma
- Shock
Death often occurs less than 10 days from the start of signs and symptoms.
One reason the viruses are so deadly is that they interfere with the immune system's ability to mount a defense. But scientists don't understand why some people recover from Ebola and Marburg and others don't.
For people who survive, recovery is slow. It may take months to regain weight and strength, and the viruses remain in the body for many weeks. People may experience:
- Hair loss
- Sensory changes
- Liver inflammation (hepatitis)
- Weakness
- Fatigue
- Headaches
- Eye inflammation
- Testicular inflammation
