Marburg fever is transmitted by blood, biological fluids, secretions and infected human or animal tissue. Those who come into contact with infected patients have a high risk of contamination. The incubation period of the virus that causes the disease - the interval between the time the person contracts the virus and the onset of the disease - is estimated to be between three and ten days.
The acute phase of the disease occurs between seven and 15 days after the first symptoms.
The funerary rituals of patients who die from illness also contribute to the transmission of the virus in some African communities. Contact with certain contaminated animals, such as monkeys and antelopes, infected or dead are another source of infection. Therefore, educating communities affected by fever about the disease and precautions to reduce the risk of contamination is essential.
