Marburg virus outbreak spreads in Tanzania, WHO offers support.
Tanzania has reported its first outbreak of Marburg virus disease (MVD), with eight cases and five deaths reported so far. The affected region borders three countries and Lake Victoria, increasing the risk of cross-border spread. The fatality ratio of MVD can be up to 90%, and healthcare workers are at risk of infection. The World Health Organization (WHO) has deployed Rapid Response Teams to investigate and implement interventions, including contact tracing and risk communication activities. The risk of spread is assessed as very high at the national level, high at the subregional level, and moderate at the regional level. WHO advises against any travel and trade restrictions with Tanzania.
