The World Health Organization says that Equatorial Guinea has confirmed its first-ever outbreak of Marburg disease, saying the Ebola-related virus is responsible for at least nine deaths in the tiny Western African country.
In a statement on Monday, the U.N. health agency confirmed the epidemic after samples from Equatorial Guinea were sent to a lab in Senegal to pinpoint the cause of the disease after an alert from a local health official last week.
The WHO said there were currently nine deaths and 16 suspected cases with symptoms including fever, fatigue, diarrhea, and vomiting. The agency said it was sending medical experts to help officials in Equatorial Guinea stop the outbreak and was also sending protective equipment for hundreds of workers.
Like Ebola, the Marburg virus originates in bats and spreads between people via close contact with the bodily fluids of infected people, or surfaces, like contaminated bed sheets. Without treatment, Marburg can be fatal in up to 88% of people.
The rare virus was first identified in 1967 after it caused simultaneous outbreaks of disease in laboratories in Marburg, Germany and Belgrade, Serbia. Seven people died who were exposed to the virus while conducting research on monkeys.
There are no authorized vaccines or drugs to treat Marburg, but rehydration treatment to alleviate symptoms can improve the chances of survival.
In a 2004 outbreak in Angola, Marburg killed 90% of 252 people infected. Last year, there were two reported Marburg deaths in Ghana.
