Authorities are reporting 11 confirmed cases of Ebola in the Democratic Republic of the Congo (DRC) which are all linked to a patient who it is believed had a relapse.
In its latest disease outbreak update, the WHO said the cases, which were identified between 11 and 17 December, were reported from three different health zones but linked to a case in Aloya Health Area in which one individual was a potential source of infection for 28 people. “Based on the preliminary sequencing of samples from this individual, this is being classified as a relapse of EVD,” it said.
While cases of relapse have been documented during past outbreaks, this is the first relapse documented in this outbreak.
As of 17 December, a total of 3,351 Ebola virus disease (EVD) cases have been reported, including 3,233 confirmed and 118 probable cases. A total of 2,217 people have died.
Of the total confirmed and probable cases, 5 per cent (n=169) were healthcare workers, while over a quarter of all confirmed EVD cases have been children aged less than 18 years (28%). The case fatality ratio (CFR) among children aged 1-4 years is 78 per cent and among children under one year is 70 per cent.
