The World Health Organization has declared Ghana's first outbreak of the Ebola-like Marburg virus disease after labs confirmed the infections in two cases announced earlier this month. The disease, a very infectious hemorrhagic fever in the same family as Ebola, is spread to people by fruit bats and transmitted among people through direct contact with bodily fluids of infected people and surfaces, WHO said. A preliminary analysis of samples from two patients from Ghana's southern Ashanti region — both of whom died and were unrelated — turned up positive, but were forwarded for full confirmation to the Institute Pasteur in Dakar, Senegal. That U.N. health agency lab corroborated the results from the Noguchi Memorial Institute for Medical Research in Ghana, WHO said in a statement Sunday. More than 90 contacts, including health workers and community members, have been identified and are being monitored, WHO said. Marburg is potentially very harmful and deadly: Case fatality rates in past outbreaks have ranged from 24% to 88%. This outbreak marks only the second time that the disease has been detected in West Africa — after Guinea confirmed a single case detected in August, according to WHO. The outbreak in Guinea was declared over five weeks later. Previous Marburg outbreaks and individual cases have appeared in Angola, Congo, Kenya, South Africa and Uganda, WHO said. — Agencies
