In brief
Despite initial denials from health officials, Tanzania's government has confirmed its first case of Marburg virus in Kagera, prompting escalated health responses and investigations into suspected cases.
Tanzania's President Samia Suluhu Hassan has officially announced an outbreak of the Marburg virus, an Ebola-like pathogen, following a swift pivot from previous government assurances that there were no cases. During a press briefing held alongside the World Health Organization (WHO) on Monday, President Samia confirmed a case in the north-western region of Kagera and stated that the government was resolute in managing the situation. Just last week, Health Minister Jenista Mhagama had reported no confirmed cases after assessing samples from suspected individuals, asserting that they tested negative for the Marburg virus. However, WHO had reported earlier in January a possible outbreak, correlating nine suspected cases and eight fatalities over a recent five-day period. At the press conference, President Samia emphasized the government's proactive measures, noting that a rapid response team has been mobilized to investigate all suspected cases. Symptoms of the Marburg virus include high fever, severe muscle pain, vomiting, and diarrhea, which can lead to significant mortality, as the virus has an average fatality rate of approximately 50%. In addition to the confirmed case, health authorities have collected samples from 24 individuals showing potential symptoms, all of which have returned negative results thus far. The exact circumstances surrounding the eight reported deaths by the WHO remain unclear at this point. The Marburg virus made its debut in Tanzania in March 2023, claiming six lives during an outbreak in the Bukoba district over two months. Dr. Tedros Adhanom Ghebreyesus, the WHO director-general, characterized the current global risk from Tanzania's outbreak as "low" while emphasizing the urgency for collaborative efforts, despite the absence of specific treatments or vaccines for the virus.Following the outbreak declaration, Africa CDC has identified over 300 contacts for further monitoring, including health workers and individuals who had direct interaction with the suspected cases. As Kagera serves as a transit hub connecting multiple countries, including Uganda and the Democratic Republic of the Congo, an acute public health response is essential to contain potential cross-border transmission.The Marburg virus is primarily transmitted from fruit bats to humans and spreads through contact with the bodily fluids of infected individuals. With previous outbreaks in neighboring countries, the Tanzanian government is closely monitoring the situation to contain this emerging health threat.
