The World Health Organization (WHO) has raised concerns about a potential outbreak of Marburg virus disease (MVD) in Tanzania.
As of January 15, 2025, nine cases have been reported in the Kagera region, with eight fatalities.
“We are currently aware of nine cases thus far, including eight people who have died,” stated WHO Director-General Tedros Adhanom Ghebreyesus on social media. “We anticipate additional cases in the coming days as disease surveillance efforts are strengthened.” 
This news comes shortly after Rwanda declared an end to its own Marburg virus outbreak in December 2024. That outbreak, which began in September 2024, resulted in 66 reported cases and 15 confirmed deaths.
Marburg Virus: A Serious Public Health Threat
Marburg virus is a highly infectious disease belonging to the same family as the Ebola virus. It causes severe viral hemorrhagic fever in humans, characterized by high fever, severe headache, and muscle weakness.
The virus is transmitted to humans from fruit bats and can spread through direct contact with bodily fluids of infected individuals.
There are currently no licensed vaccines or antiviral treatments available for Marburg virus. Supportive care, including fluid replacement and medication to manage symptoms, is the mainstay of treatment.
WHO Monitoring the Situation Closely
The WHO is actively monitoring the situation in Tanzania and collaborating with health authorities to investigate the outbreak, identify contacts, and implement control measures. Public health officials are urging people in the affected region to practice good hygiene and avoid contact with sick individuals or animals.
This potential outbreak highlights the importance of global health surveillance and rapid response mechanisms to contain the spread of infectious diseases. Sources and related content
