Authorities in Equatorial Guinea have announced the first-ever outbreak of the Marburg virus, the World Health Organization (WHO) said. At least nine people reportedly died in the western province of Kientem. Preliminary tests have tested positive for viral hemorrhagic fever. So far, 16 suspected cases have been reported with symptoms including fever, fatigue, and vomiting with blood. According to the WHO, Marburg virus is transmitted to humans from fruit bats and spreads to humans through direct contact with the bodily fluids of infected individuals as well as surfaces and materials. At the moment there are no registered vaccines or antiviral drugs to treat the fever, the organization summarized.
