Causes & Risk Factors
Several factors can contribute to Marburg Virus Disease.
Marburg virus disease is caused by the Marburg virus, a member of the filovirus family that also includes Ebola virus.
Marburg virus disease is caused by the Marburg virus, a member of the filovirus family that also includes Ebola virus. The virus naturally lives in fruit bats, specifically the Egyptian fruit bat species found in caves and mines across parts of Africa. These bats can carry the virus without becoming sick themselves, making them what scientists call a natural reservoir host.
People typically become infected through direct contact with infected bats, their droppings, or contaminated cave environments.
People typically become infected through direct contact with infected bats, their droppings, or contaminated cave environments. Once a person becomes infected, the virus can spread from person to person through direct contact with blood, saliva, sweat, tears, mucus, vomit, feces, breast milk, urine, or semen of infected individuals. The virus can also spread through contact with contaminated surfaces, clothing, or medical equipment.
The virus enters the body through broken skin, mucous membranes in the eyes, nose, or mouth, or through cuts and scrapes.
The virus enters the body through broken skin, mucous membranes in the eyes, nose, or mouth, or through cuts and scrapes. Healthcare workers face increased risk when caring for infected patients without proper protective equipment. Family members caring for sick relatives also face higher exposure risk, which explains why outbreaks often cluster within households and healthcare facilities.
Risk Factors
- Living in or traveling to central and eastern Africa
- Working in caves or mines where fruit bats live
- Direct contact with infected wildlife, especially bats
- Caring for infected patients without protective equipment
- Working in laboratories handling the virus
- Close contact with infected family members
- Participating in burial rituals involving infected individuals
- Healthcare work in outbreak areas
- Handling contaminated medical equipment or clothing
- Recent travel to areas with active outbreaks
Diagnosis
How healthcare professionals diagnose Marburg Virus Disease:
- 1
Diagnosing Marburg virus disease requires careful evaluation because early symptoms resemble many other tropical diseases like malaria, typhoid fever, or other viral hemorrhagic fevers.
Diagnosing Marburg virus disease requires careful evaluation because early symptoms resemble many other tropical diseases like malaria, typhoid fever, or other viral hemorrhagic fevers. Doctors typically start by taking a detailed travel history and assessing potential exposure risks, such as recent visits to caves, contact with bats, or proximity to known cases. The combination of sudden severe illness with bleeding symptoms in someone with relevant exposure history raises suspicion for Marburg virus disease.

Laboratory testing provides definitive diagnosis, though several different tests may be needed depending on how long someone has been sick.
Laboratory testing provides definitive diagnosis, though several different tests may be needed depending on how long someone has been sick. During the first few days of illness, doctors can detect the virus itself using RT-PCR testing or by finding viral proteins in blood samples. Later in the illness, antibody tests can show if someone's immune system has responded to the virus. All testing requires specialized laboratories with high-level biosafety capabilities due to the dangerous nature of the virus.

Other important tests help doctors assess the disease's impact on the body and guide treatment decisions.
Other important tests help doctors assess the disease's impact on the body and guide treatment decisions. These typically include complete blood counts to check for low platelets and white blood cells, liver function tests, kidney function assessments, and coagulation studies to evaluate bleeding risk. Doctors must carefully follow strict isolation procedures during examination and testing to protect themselves and prevent further transmission.
Complications
- Marburg virus disease can lead to severe complications affecting multiple organ systems, particularly when treatment is delayed or unavailable.
- The most dangerous complication is severe bleeding, both internal and external, which can lead to shock and death.
- The virus damages blood vessels and interferes with normal clotting, causing bleeding from the mouth, nose, injection sites, and internally in the digestive tract or other organs.
- Other serious complications include liver failure, kidney failure, central nervous system problems like confusion or seizures, and severe dehydration from persistent vomiting and diarrhea.
- Some patients develop secondary bacterial infections due to weakened immune systems.
- Pregnant women face additional risks, as the virus can cause miscarriage, premature labor, or severe bleeding during delivery.
- Even among survivors, recovery may be complicated by long-lasting effects including joint pain, liver problems, eye inflammation that can affect vision, hair loss, and psychological effects from the traumatic illness experience.
Prevention
- Preventing Marburg virus disease centers on avoiding exposure to the virus, particularly in regions where fruit bats carry the infection.
- People living in or traveling to affected areas should avoid entering caves or mines where bats roost, especially in Uganda, Kenya, and other parts of central and eastern Africa.
- If cave exploration is necessary for work or research, wearing protective equipment including gloves, masks, and protective clothing significantly reduces risk.
- During outbreaks, prevention focuses on breaking transmission chains through careful hygiene and isolation measures.
- Frequent handwashing with soap and water or alcohol-based sanitizers, avoiding contact with sick individuals, and staying away from healthcare facilities treating suspected cases helps protect healthy people.
- Healthcare workers require specialized training and equipment, including impermeable gowns, gloves, masks, and eye protection when caring for suspected or confirmed cases.
- Community education plays a vital role in outbreak prevention and control.
- Local health authorities work to educate communities about recognizing symptoms, reporting suspected cases promptly, and following safe burial practices that prevent transmission from deceased individuals.
- International travelers should stay informed about current outbreak situations and follow guidance from health authorities about travel restrictions or precautions in affected areas.
Currently, no specific antiviral medications or approved vaccines exist for Marburg virus disease, making supportive care the cornerstone of treatment.
Currently, no specific antiviral medications or approved vaccines exist for Marburg virus disease, making supportive care the cornerstone of treatment. Early and aggressive supportive care significantly improves survival rates by helping the body fight the infection while managing dangerous complications. Treatment focuses on maintaining proper fluid balance, supporting blood pressure, providing oxygen when needed, and managing pain and fever.
Intravenous fluids help replace fluid losses from vomiting, diarrhea, and bleeding, while careful monitoring prevents fluid overload that could harm the heart or lungs.
Intravenous fluids help replace fluid losses from vomiting, diarrhea, and bleeding, while careful monitoring prevents fluid overload that could harm the heart or lungs. Blood products like platelets, plasma, or red blood cells may be needed to address severe bleeding or anemia. Pain medications help manage the severe headaches and muscle aches, though doctors must carefully choose medicines that don't increase bleeding risk.
Several experimental treatments show promise in research studies and may be available through compassionate use programs during outbreaks.
Several experimental treatments show promise in research studies and may be available through compassionate use programs during outbreaks. These include monoclonal antibody treatments designed to target the virus specifically, antiviral drugs that interfere with viral replication, and convalescent plasma from recovered patients. However, these treatments remain investigational and require careful consideration of risks and benefits.
Isolation in specialized medical facilities protects both the patient and others from infection spread.
Isolation in specialized medical facilities protects both the patient and others from infection spread. Healthcare teams use strict infection control measures including full protective equipment, negative pressure rooms when possible, and careful disposal of contaminated materials. Recovery can take weeks to months, with some patients experiencing lingering effects like joint pain, vision problems, or fatigue that may persist for extended periods.
Living With Marburg Virus Disease
Survivors of Marburg virus disease often face a challenging recovery period that requires patience and comprehensive medical support. The acute illness typically lasts 1-2 weeks, but full recovery can take several months. Many survivors experience persistent fatigue, joint and muscle pain, headaches, and difficulty concentrating during the recovery phase. Some develop eye problems including inflammation, light sensitivity, or vision changes that may require ongoing ophthalmologic care.
