Marburg haemorrhagic fever in Uganda

The Ministry of Health in Uganda have reported an outbreak of Marburg haemorrhagic fever in Kabale district in South-western Uganda [1]. As of 21 October 2012, a total of nine cases have been reported, including five deaths, since the beginning of the outbreak [2].The first four fatal cases, three of which have been laboratory confirmed, occurred in the same family in Kiyonjo parish in Kitumba sub-county of Kabale district on 4 October 2012.

The Ministry of Health and the World Health Organization (WHO) have deployed a team to the district to support the outbreak investigation and response, including case contact tracing [1-2].

Marburg haemorrhagic fever

Marburg haemorrhagic fever is a severe disease caused by a virus of the Filoviridae family. It is highly transmissible by direct contact with blood, secretions, or other bodily fluids of dead or living infected persons. Transmission can also occur by contact with infected animals (through bats in mines or caves).

Marburg virus causes an acute febrile illness accompanied by severe haemorrhagic manifestations. The disease presents with the sudden onset of fever, headache, joint and muscle aches, and weakness. As infection progresses, nausea, vomiting and diarrhoea, shortness of breath, confusion, and haemorrhage can all occur. This can lead to multi-organ failure, shock, and death in severe cases (25% to 90% cases).

Advice for travellers

The likelihood of travellers contracting Marburg is low unless there has been direct contact with the blood or body fluids of infected persons, or with objects, such as needles, that have been contaminated with body fluids [3].

Travellers who think they may have been exposed to Marburg virus should seek medical attention immediately if they experience any of the above symptoms within the first 21 days of return to the UK or 21 days after exposure.

WHO does not recommend that any travel or trade restrictions are applied to Uganda [2].
