Outbreak Brief 6: Ebola virus disease (EVD) Outbreak

31 March 2021

Outbreak Update: Since the last brief (24 March 2021), no new cases or deaths have been reported. However, one new recovery of Ebola virus disease (EVD) has been reported from Guinea. Cumulatively, 30 EVD cases, 15 deaths (CFR: 50%), and 15 recoveries have been reported from DR Congo (12 cases; 6 deaths; 6 recoveries) and Guinea (18; 9; 9) – see Table 1 for the subnational breakdown. Seven healthcare workers are amongst the confirmed cases: DR Congo (2) and Guinea (5).
It has been 22 and 19 days since the last confirmed cases were reported from DR Congo and Guinea, respectively. There are no active cases in both Member States. The last EVD patients were discharged on 22 and 25 March 2021 in DRC and Guinea, respectively. Provided that no new confirmed cases are reported, the outbreaks will be declared over in 37 days for Guinea and 36 days for DRC.
Genomic sequencing of EVD positive samples in Guinea show that this new outbreak is the result of a resurgence of the strain responsible for the 2014-2016 West African outbreak. Sequencing was performed at the Centre de Recherche et de Formation en Infectiologie de Guinée (CERFIG).
