WHO is working to contain an outbreak of Marburg virus disease (MVD) that has appeared in eastern Uganda on the border with Kenya. At least one person is confirmed to have died of MVD and several hundred people may have been exposed to the virus at health facilities and at traditional burial ceremonies in Kween District, a mountainous area 300 kilometres northeast of Kampala.The woman’s brother had also died of similar symptoms three weeks earlier and was buried at a traditional funeral. He worked as a game hunter and lived near a cave inhabited by Rousettus bats, which are natural hosts of the Marburg virus.
One suspected and one probable case are being investigated and provided with medical care. An active search for people who may have been exposed to or infected by the virus is underway.
The Ministry of Health has sent a rapid response team to the area supported by staff from the World Health Organization, the Centers for Disease Control and Prevention (CDC) and the African Field Epidemiology Network (AFNET).
WHO is providing medical supplies, guidance on safe and dignified burials, and has released USD 500 000 from its Contingency Fund for Emergencies to finance immediate response activities.
“We are working with health authorities to rapidly implement response measures,” said Ibrahima-Soce Fall, WHO Regional Emergency Director for the Africa region. “Uganda has previously managed Ebola and Marburg outbreaks but international support is urgently required to scale up the response as the overall risk of national and regional spread of this epidemic-prone disease is high.”
Marburg virus disease is a rare disease with a high mortality rate for which there is no specific treatment.
Notes to editors
Marburg virus disease (MVD) is a severe and highly fatal disease caused by the Marburg virus from the Filoviridae family; the same family as the Ebola virus. This virus is among the most virulent pathogens known to infect humans. The incubation period is 2-21 days, and symptom onset is sudden and marked by fever, chills, headache, and myalgia. Although MVD is rare, it can result in large outbreaks with high case fatality rates (CFR range from 23 to 90%). The disease is transmitted by direct contact with the blood, body fluids and tissues of infected persons or wild animals (e.g. monkeys and fruit bats).
In Uganda, the following MVD outbreaks have been recently documented:
2007: 4 cases, including 2 deaths, in Ibanda District, Western Uganda
2008: 2 unrelated cases in travelers returning to the Netherlands and USA, respectively after visiting caves in Western Uganda
2012: 15 cases, including 4 deaths, in Ibanda and Kabale districts, Western Uganda
2014: 1 case in healthcare professional from Mpigi District, Central Uganda.
