Marburg Virus: Symptoms, Transmission, Prevention, and Treatment
Marburg virus is a rare but highly dangerous virus that belongs to the family Filoviridae, which also includes the Ebola virus. The virus causes Marburg hemorrhagic fever, a severe and often fatal disease in humans. The Marburg virus was first identified in 1967 during outbreaks in Marburg and Frankfurt, Germany, and in Belgrade, Yugoslavia, among laboratory workers who were exposed to infected monkeys imported from Uganda.
Symptoms of Marburg Hemorrhagic Fever
The Marburg virus causes sudden onset of symptoms that include fever, chills, headache, myalgia, and a maculopapular rash on the trunk. The disease progresses rapidly, and nausea, vomiting, chest pain, sore throat, and diarrhea may follow.
As the condition deteriorates, the patient may experience jaundice, inflammation of the pancreas, weight loss, delirium, shock, liver failure, massive hemorrhaging, and dysfunction of multiple organs.
The case-fatality rate of Marburg hemorrhagic fever ranges from 23% to 90%, depending on the outbreak and the quality of medical care available. The disease is most severe in the early stages of infection, and patients who survive the initial phase of the illness may recover more slowly and experience complications such as orchitis, ocular inflammation, or neurological sequelae.
Transmission of Marburg Virus
The natural reservoir of the Marburg virus is thought to be fruit bats of the Pteropodidae family, which can carry the virus without showing any signs of illness. The virus can be transmitted to humans through contact with the bodily fluids or tissues of infected animals, such as monkeys, bats, or rodents.
Human-to-human transmission can occur through direct contact with the blood, secretions, organs, or other bodily fluids of an infected person, especially during the late stages of illness when the viral load is high. Healthcare workers and family members of infected patients are at the highest risk of contracting the disease.
Prevention of Marburg Virus
The prevention of Marburg virus infection remains problematic as researchers are still studying the transmission of the virus from wildlife to humans.
However, avoiding contact with fruit bats and sick non-human primates in central Africa is one way to protect against infection. People who handle animals or their tissues in high-risk areas should wear protective clothing and gloves, and practice good hygiene, such as frequent hand washing.
If a patient is either suspected or confirmed to have Marburg hemorrhagic fever, barrier nursing techniques should be used to prevent direct physical contact with the patient. Patients with the disease should be isolated in a separate room with dedicated medical equipment and disposable supplies, and healthcare workers should wear personal protective equipment, such as gowns, gloves, masks, and goggles.
Treatment of Marburg Hemorrhagic Fever
Although there is no specific treatment for Marburg hemorrhagic fever, administering supportive care such as hydration and symptomatic treatment can increase the chances of survival.
Patients with severe or complicated diseases may require advanced medical interventions, such as mechanical ventilation, renal replacement therapy, or hemodynamic support.
A range of blood, immunological, and drug therapies are under development, but as yet, there is no licensed treatment proven to neutralize the virus. Research is ongoing to identify effective treatments and vaccines for Marburg hemorrhagic fever.

Marburg virus poses a grave public health threat, and it is of utmost importance for individuals to take preventative measures to minimize the risk of transmission. Public health experts are making relentless efforts to devise efficacious treatment options and a vaccine to thwart the virus’s spread. In the meantime, individuals can do their part by taking steps to protect themselves and their communities. If you live in or travel to an area where Marburg hemorrhagic fever is endemic, be sure to avoid contact.
