Ebola and Marburg haemorrhagic fevers: outbreaks and case locations

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

Current incidents and outbreaks

A new outbreak of Ebola virus disease (EVD) was declared in Équateur Province, western Democratic Republic of the Congo (DRC), on 1 June 2020. As of 3 August, there had been 73 cases (69 confirmed and 4 probable) reported from 8 health zones in the province.

On 25 June 2020, the World Health Organization (WHO) declared the EVD outbreak in eastern DRC to be over. The outbreak, which started in North Kivu province on 1 August 2018, was the second-largest in the world and was particularly challenging as it took place in an active conflict zone. There were a total of 3,470 cases, 2,287 deaths and 1,171 survivors.

Following this declaration, on 26 June 2020, the International Health Regulations (IHR) Emergency Committee agreed that the outbreak in Ituri, North Kivu and South Kivu provinces no longer constituted a public health emergency of international concern.

On 10 September 2019, WHO was made aware of unofficial reports of an unexplained death of a person in Dar es Salaam, United Republic of Tanzania. It appears probable this was an Ebola-related death. As of 31 October 2019, Public Health England (PHE) believes there is no evidence of ongoing active transmission of Ebola in Tanzania.

Outbreaks in 2017 and 2018

On 8 May 2018, WHO reported an Ebola virus disease outbreak in DRC’s Equateur Province. There were 54 cases (38 confirmed and 16 probable), and the outbreak was declared over on 24 July 2018.

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 2017

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. 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 more than 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.
