Marburg virus disease
- Also known as Marburg hemorrhagic fever
- RNA virus of the filovirus family
- The 5 species of Ebola are the other 5 members of the family
- First outbreak, 1967, in Marburg and Frankfurt Germany - due to research on African green monkeys
- Reservoir: Egyptian fruit bat (Rousettus aegyptiacus)
- Host animal to human - most outbreaks have implicated contact with bats as the source
- No documented cases of primate-human transmission outside laboratory setting
- Human to human: direct contact with droplets of body fluid or contaminated objects
- Incubation period: 2-21 days (5-7 days more common)
- Initial symptoms are vague:
- High fever, headache, chills, myalgias, abdominal pain, diarrhea
- Maculopapular rash, typically on the trunk, around 5 days after symptom onset
- Massive hemorrhage, shock, and multiorgan system failure
- Death usually occurs 1-2 weeks after symptom onset (23-90% fatal)
- Patients alive at 2 weeks after symptom onset usually survive
- Difficult diagnosis and very rare/unlikely outside of Central Africa
- Consider Marburg with typical symptoms and high risk exposure including:
- Close contact with African fruit bats, infected humans, infected non-human primates
- Lab researcher using African primates
- Recent travel to Uganda or other Central African countries
- Cave exploration in Africa
- Aggressive supportive care is the hallmark of management
- Strict Isolation precautions: standard, contact and droplet
- Limit entry and maintain a log of people who enter the room
- Notify public health personnel
- Continue to test and treat for other possible diseases
- Admit to ICU
