1. Situation update
From 4 to 10 May 2020, there have been no new confirmed cases of Ebola virus disease (EVD) reported in Democratic Republic of the Congo. Since the resurgence of the outbreak on 10 April 2020, seven confirmed cases have been reported from Kasanga, Malepe and Kansulinzuli Health Areas in Beni Health Zone. Of these seven cases, one case is receiving care at an Ebola treatment centre (ETC); one confirmed case who was receiving care at an ETC recovered and was discharged after two consecutive negative tests; one confirmed case remains in the community; and four cases died, including two community deaths and two deaths in the ETC in Beni. Investigations into the possible source of infection of the cluster of cases reported since 10 April 2020 are ongoing. So far, no definitive source of infection has been identified.
As of 10 May, 86 contacts are under surveillance, of which 41 (48%) are high risk contacts who had direct contact with body fluids of the last confirmed case. Contacts from the previous six cases reported in April 2020 have exited their follow-up period. Of these 86 contacts, 71 (83%) have been vaccinated. There are 10 high risk contacts who are currently voluntarily isolating in a dedicated site where essential goods and health services are provided to them.
From 4 to 10 May 2020, an average of 2497 alerts were reported and investigated per day. Of these, an average of 316 alerts were validated as suspected cases each day, requiring specialized care and laboratory testing to rule-out EVD. In the past three weeks, the alert rate has improved notably in Beni and Butembo subcoordinations. Timely testing of suspected cases continues to be provided from eight laboratories. From 4 to 10 May 2020, 2494 samples were tested including 1843 blood samples from alive, suspected cases; 318 swabs from community deaths; and 333 samples from re-tested patients. Overall, laboratory activities increased by 18% compared to the previous week.
As of 10 May 2020, a total of 3462 EVD cases, including 3317 confirmed and 145 probable cases have been reported, of which 2279 cases died (overall case fatality ratio 66%). Of the total confirmed and probable cases, 57% (n=1970) were female, 29% (n=1002) were children aged less than 18 years, and 5% (n=171) were healthcare workers. As of 10 May 2020, 1170 cases have recovered from EVD.
