Information about incidents and outbreaks of Ebola and Marburg, both viral haemorrhagic fevers (VHF).

Current incidents and outbreaks

On 8 May 2018, WHO reported an Ebola virus disease outbreak in the Democratic Republic of Congo (DRC). As of 18 June, 60 cases have been reported (38 confirmed) across 3 health zones in Equateur Province; Bikoro, Iboko and Wangata. See latest information from the DRC Ministry of Health (In French), and WHO Sitreps which include maps of the affected area.

The World Health Organization’s International Health Regulations Emergency Committee met on 18 May and determined that, at this time, the outbreak does not constitute a public health emergency of international concern.

This outbreak presents a negligible to very low risk to the UK public.

Outbreaks in 2017

A Marburg virus outbreak in Kween district, eastern Uganda, was confirmed on 17 October 2017. The 3 cases all died and WHO declared the outbreak over on 8 December.

An Ebola virus outbreak in Bas-Uele province, DRC was detected in early May 2017 but was rapidly contained. There were a total of 8 cases of which 5 were laboratory confirmed. 4 patients died. The WHO declared the outbreak over on 2 July 2017.

West Africa Ebola outbreak, 2014 to 2016

WHO confirmed an outbreak of Ebola virus disease in southeastern Guinea in March 2014. This was the first time an outbreak had been diagnosed in this part of Africa, and the index case was traced back to December 2013.

The outbreak spread to neighbouring and nearby countries, particularly Liberia and Sierra Leone, and became the largest ever known outbreak of this disease. It continued for over 2 years and a total of 28,616 confirmed, probable and suspected cases were reported in Guinea, Liberia and Sierra Leone, with 11,310 deaths.
