Current incidents and outbreaks

Republic of Guinea

On 14 February 2021, an outbreak of Ebola virus disease (EVD) was declared in Gouéké, in the prefecture of Nzérékoré, South East Guinea. This is Guinea’s second EVD outbreak, the first being the 2014 to 2016 West African EVD outbreak (see below). As of 18 February 2021, 3 confirmed and 4 probable cases have been reported, including 5 fatalities. Further cases are likely to be identified as this outbreak evolves. At this time, there is no evidence to suggest that this outbreak is related to the ongoing outbreak of EVD in the Democratic Republic of Congo (see below).

This outbreak presents a negligible to very low risk to the UK public (Public Health England (PHE) risk assessment as of 17 February 2021).

Democratic Republic of the Congo (DRC)

On 7 February 2021, an outbreak of EVD was declared in Butembo, a city in North Kivu Province in North East DRC. As of 17 February 2021, 4 confirmed cases have been reported, including 2 fatalities. Further cases are likely to be identified as this outbreak evolves.

This outbreak presents a negligible to very low risk to the UK public (PHE risk assessment as of 17 February 2021).

Previous incidents and outbreaks 2016 to 2020

2020

Équateur Province, western DRC

Between 1 June and 18 November 2020, 130 cases (119 confirmed and 11 probable) and 55 deaths were reported from 13 of the 18 health zones in the province. This was DRC’s 11th EVD outbreak.

2018 to 2020

Eastern DRC

Between 1 August 2018 and 25 June 2020, 3,470 cases, 2,287 deaths and 1,171 survivors of EVD were reported across 3 provinces in DRC: Ituri, North Kivu and South Kivu. This outbreak, DRC’s 10th, is the longest lasting EVD incident in the country’s history, and the second largest in the world after the 2014 to 2016 EVD outbreak in West Africa (see below). The response to this outbreak was particularly challenging as it took place in an active conflict zone.

2019

United Republic of Tanzania

On 10 September 2019, WHO was made aware of unofficial reports of an unexplained death of a person in Dar es Salaam. It appears probable this was an Ebola-related death.

2018

Équateur Province, western DRC

Between 8 May and 24 July 2018 DRC reported their ninth EVD outbreak which resulted in 54 cases (38 confirmed and 16 probable), including 33 deaths.

2017

Eastern Uganda

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

Bas-Uele Province, DRC

Between May and July 2017 an EVD outbreak consisting of 8 cases (5 confirmed), including 4 fatalities was recorded. This was DRC’s eighth EVD outbreak.

West Africa Ebola outbreak, 2014 to 2016

WHO confirmed an outbreak of Ebola virus disease in south-eastern 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.

See final WHO Ebola situation report, June 2016.
