What is Marburg?

Marburg virus disease is a rare and deadly disease that has, at times, caused outbreaks in several African countries. It is spread by contact with blood or body fluids of a person infected with Marburg virus. It is also spread by contact with contaminated objects (such as clothing, bedding, needles, and medical equipment) or by contact with animals, such as bats and nonhuman primates, who are infected with Marburg virus.

Marburg virus disease is a viral hemorrhagic fever. Symptoms include fever, chills, headache, muscle pain, rash, sore throat, diarrhea, vomiting, stomach pain, chest pain, and unexplained bleeding or bruising. Infection with Marburg virus is often fatal. There are no approved vaccines or therapeutics for Marburg virus disease.
