The Ministry of Health (MoH) of the United Republic of Tanzania declared an outbreak of Marburg virus disease (MVD) in the country. As of 22 March, a total of eight cases, including five deaths (case fatality ratio [CFR]: 62.5%) have been reported from two villages in Bukoba district, Kagera region, United Republic of Tanzania. Two of these cases were healthcare workers, one of whom has died. This is the first Marburg virus disease outbreak reported in the country.
As response measures, Rapid Response Teams have been deployed to investigate and implement interventions in the affected areas, including contact tracing and risk communication activities.
WHO assesses the risk of spread as very high at the national level, high at the subregional level, and moderate at the regional level due to cross-border movements between Kagera region and bordering countries including Uganda in the north, Rwanda and Burundi in the west. The risk at the global level is assessed to be low.
