Tanzania declares end of Marburg viral outbreak

Tanzania has declared the end of its first-ever outbreak of Marburg, a deadly Ebola-like virus with a fatality rate of up to 88%, the World Health Organisation (WHO) said on Friday. Nine cases, including six deaths, were recorded in the outbreak, which was declared in March in the northwest Kagera region, WHO said. Marburg’s symptoms include fever, headache, fatigue and blood-stained vomit and diarrhoea. It is from the same virus family responsible for Ebola and is passed on to people from fruit bats. While there are no vaccines or antiviral treatments for Marburg, WHO said timely intervention by its local office along with government efforts helped prevent the disease from spreading. “Tanzania has been able to end this outbreak and limit the potentially devastating impacts of a highly infectious disease,” said Matshidiso Moeti, its director for Africa. Speaking at an event in northwest Tanzania, the government’s chief medical officer Tumaini Nagu said WHO guidelines were closely followed before declaring the outbreak as over. The last confirmed case in Tanzania tested negative on April 19. An outbreak is declared as over after a mandatory countdown of 42 days. Rapid human development has pushed people deeper into the habitats of bats that transmit Marburg, Ebola and other viruses, amplifying the risk of global pandemics, scientists say. Over the past two years, Marburg outbreaks have occurred in four African countries where the virus had not previously been detected in humans, including Tanzania and Equatorial Guinea, which has been responding to an outbreak since February. WHO Director General Tedros Adhanom Ghebreyesus said in a media briefing the outbreak in Equatorial Guinea would be declared over next week if no further cases are detected there.
