Marburg virus

The Marburg virus belongs to the family Filoviridae. This family is responsible for some of the most pathogenic viral infections in humans.

Marburg virus looks like Ebola, but it's less lethal.

About the virus

It represents a very high biohazard. It must therefore be handled in a P4 laboratory, a laboratory for class 4 pathogenic viruses.

Its appearance

It first appeared in 1967, in Germany in Marburg, hence its name. In the Behring laboratory in Marburg, 31 people were affected, 7 of whom died.

The first known outbreaks occurred in East Africa where there have been two major epidemics: one in the Democratic Republic of Congo in 2000 and the other in Angola in 2005.

Victims

The first two cases were young Europeans. They both died of the virus after visiting Kitum Cave in Kenya, the first died in 1980 and the second in 1987.

In 2007, a study proved that a bat, Rousettus aegypticus, is a natural carrier of the virus. This These bats were in the Kitum Cave and transmitted the virus to the two Europeans.

Before 2000, cases were rares rare and were mainly distributed seen in South and East African countries such as Kenya, Zimbabwe and South Africa.

Until the Spring of 2005, the victims were all young. No adults were infected before this saison season.

Events

- In 1998, 149 people were affected infected in Durba, in the north-eastern part of the Democratic Republic of the Congo. More than 90% of these people are dead died .

- In 2005, in the north of Angola, there were 252 people affected infected , including 227 dead. The case-fatality rate was about 90%, which is comparable to Ebola.

- In Angola, since 2004, 400 cases have occurred.

Symptoms

The incubation period lasts from 2 to 21 days. The main symptom is severe hemorrhagic fever. Other symptoms include diarrhea, severe headache, malaise, abdominal pain and cramps, nausea and vomiting.

For fatal cases, victims die on the 8th or 9th day after the onset of symptoms. The death is preceded by significant blood loss.

Transimission and treatment

Transmission is by close contact with an affected infected person or their bodily fluids.

There is no specific treatment or vaccine for the Marburg virus.
