The outbreak was declared over on June 19, 2021. a survivor) and not a new introduction of the virus from the animal reservoir. While researchers cannot definitively determine the cause of the outbreak, findings strongly support the conclusion that the outbreak was likely caused by a persistent source of infection (i.e. Sequencing of samples from the outbreak was conducted and compared to sequences from cases during the 2014–2016 West Africa outbreak. These are the first cases of EVD confirmed in Guinea since the 2014–2016 West Africa outbreak, the largest in history, was declared over. On February 14, 2021, the Ministry of Health (MOH) in Guinea announced that cases of Ebola virus disease (EVD) had been confirmed in N’Zérékoré Prefecture, a forested rural region in southeast Guinea. Reported number of deaths and percentage of fatal cases: 12 (52.2%).The outbreak was declared over on May 3, 2021. Sequencing of samples suggests that cases in this outbreak were linked to cases in the area during the 2018–2020 outbreak and likely resulted from persistent infection in a survivor that led to either a relapse or sexual transmission of the virus. North Kivu was previously affected by EVD during the 2018–2020 Ebola outbreak, the largest in DRC’s history, which was declared over on June 25, 2020.

Sequencing data showed a link to the 2018-2020 outbreak in the same region, suggesting this outbreak was likely caused by a persistent infection in an EVD survivor. Subsequent cases were confirmed in the same health zone and three probable cases were retrospectively identified from September 2021. On October 8, the Ministry of Health in DRC announced an outbreak of EVD in Beni Health Zone, North Kivu Province.

The following four cases were epidemiologically linked, or had known contact with an EVD patient, and were reported from Mbandaka and Wangata health zones. Sequencing data from the first confirmed case in this outbreak indicated that this was a new spillover event from an animal to a person and was not directly linked to previous outbreaks. This was the 14 th EVD outbreak in DRC and marked the third in a series of outbreaks in Equateur province since 2018. On April 23, the Ministry of Health of the Democratic Republic of the Congo (DRC) declared an outbreak of EVD in Mbandaka city, Equateur Province. Reported number of deaths and percentage of fatal cases: 5 (100%).The outbreak was declared over on September 27, 2022, with only one confirmed case. A specimen was collected and tested positive at the Beni Referral Hospital laboratory and later confirmed at the DRC’s national laboratory in Goma – the Institut National de la Recherche Biomédicale (INRB).

This marks the sixth Ebola outbreak in Uganda. A sample from the patient was sent to the VHF laboratory at the Uganda Virus Research Institute, where Ebola disease (species Sudan ebolavirus) was confirmed. This announcement came after a patient with a suspected viral hemorrhagic fever (VHF) was identified and isolated at Mubende Regional Referral Hospital. On September 20, 2022, the Ministry of Health confirmed an outbreak of Ebola (Sudan virus) in Mubende District, in western Uganda. Reported number of deaths and percentage of fatal cases: 55 (34%).
