Tanzania reported its first outbreak of the deadly Marburg virus after eight people developed symptoms including fever, vomiting, bleeding and kidney failure. Testing by the east African country confirmed the presence of the highly virulent disease that causes hemorrhagic fever, the World Health Organization said in a statement late Tuesday. Five of the eight cases in Tanzania’s northwest Kagera region have died and another 161 contacts have been identified and are being monitored, the WHO said. Tanzania is the second African country this year to report its first Marburg outbreak after Equatorial Guinea in February detected the illness.
