Deadly Marburg virus discovered for first time in west Africa
Health authorities in Guinea have confirmed one death from Marburg virus, a highly infectious haemorrhagic fever similar to Ebola, the World Health Organization says.
It marks the first time that the deadly disease has been identified in west Africa.
There have been 12 major Marburg outbreaks since 1967, mostly in southern and eastern Africa.
Guinea’s new case was first identified last week, just two months after the country was declared free of Ebola following a brief flare-up earlier this year that killed 12 people.
The patient, who has since succumbed to the illness, first sought treatment at a local clinic before his condition rapidly deteriorated, the WHO said on Monday.
Analysts at Guinea’s national haemorrhagic fever laboratory and the Institute Pasteur in Senegal later confirmed the Marburg diagnosis.
“The potential for the Marburg virus to spread far and wide means we need to stop it in its tracks,” Matshidiso Moeti, WHO’s regional director for Africa, said.
“We are working with the health authorities to implement a swift response that builds on Guinea’s past experience and expertise in managing Ebola, which is transmitted in a similar way,” Moeti said.
Both the Marburg case and this year’s Ebola cases were detected in Guinea’s Gueckedou district, near the borders with Liberia and Ivory Coast. The first cases of the 2014-2016 Ebola epidemic, the largest in history, also were from the same region in south-eastern Guinea’s forest region.
Marburg case fatality rates have varied from 24% to 88% in past outbreaks, depending on virus strain and case management, WHO said, adding that transmission occurred through contact with infected body fluids and tissue, The Guardian reported.
Marburg outbreaks start when an infected animal, such as a monkey or a fruit bat, passes the virus to a human. The virus then spreads from human to human by contact with an infected person’s body fluids. Symptoms include headache, vomiting blood, muscle pains and bleeding through various orifices.
