Introduction
Marburg virus disease is a rare but severe hemorrhagic fever caused by the Marburg virus, a close relative of the Ebola virus. The disease can cause outbreaks with high fatality rates and is considered a public health emergency when it occurs. Marburg virus disease is most commonly reported in parts of Africa, but awareness and preparedness are important worldwide due to the potential for international spread.
Causes
Marburg virus disease is caused by infection with the Marburg virus, a filovirus. The virus is transmitted to humans from:
- Contact with Infected Animals: Most often fruit bats (Rousettus aegyptiacus) or monkeys.
- Direct Contact with Body Fluids: Blood, saliva, vomit, urine, or other secretions of infected people.
- Contaminated Surfaces or Materials: Such as bedding, clothing, or medical equipment.
Human-to-human transmission occurs through direct contact with the bodily fluids of an infected person, especially in healthcare or caregiving settings.
Symptoms
Symptoms usually appear 2 to 21 days after exposure and may include:
- Sudden High Fever
- Severe Headache
- Muscle Aches and Weakness
- Fatigue
- Chills
- Nausea and Vomiting
- Abdominal Pain and Diarrhea
- Sore Throat
- Rash
- Red Eyes
As the disease progresses, it can cause:
- Severe Hemorrhaging: Bleeding from the gums, nose, eyes, or other sites
- Organ Failure
- Shock
- Confusion or Delirium
The disease can be fatal, with death often occurring 8 to 9 days after symptom onset in severe cases.
When to Seek Medical Attention
Seek immediate medical care if you develop symptoms of hemorrhagic fever after recent travel to or contact with someone from an area with a Marburg outbreak, or after exposure to bats or nonhuman primates.
Diagnosis
Diagnosis is based on:
- Medical History: Recent travel, exposure to bats or monkeys, or contact with infected individuals.
- Laboratory Tests: Blood tests (PCR, ELISA) to detect Marburg virus or antibodies.
Treatment Options
There is no specific antiviral treatment for Marburg virus disease. Management focuses on supportive care:
- Isolation: To prevent transmission to others.
- Supportive Care: Includes intravenous fluids, electrolyte management, oxygen therapy, and treatment of secondary infections.
- Monitoring and Management: Of complications such as bleeding, organ failure, and shock.
- Experimental Treatments: Some antiviral drugs and monoclonal antibodies are under investigation.
Prevention
Preventive strategies focus on reducing exposure and rapid response to outbreaks:
- Avoid Contact: With bats, monkeys, and people who are sick or have died from hemorrhagic fever.
- Use Personal Protective Equipment (PPE): For healthcare workers and caregivers.
- Safe Burial Practices: To prevent transmission from deceased individuals.
- Infection Control: Strict protocols in healthcare settings.
Takeaway
Marburg virus disease is a rare but deadly hemorrhagic fever with no specific cure. Early recognition, isolation, and supportive care are essential for improving outcomes and preventing the spread of the virus. Stay informed about outbreaks and follow public health recommendations, especially when traveling to affected areas.
