Democratic Republic of Congo: Ebola Virus Disease - External Situation Report 15
1. Situation update
The Ministry of Health and WHO continue to closely monitor the outbreak of Ebola virus disease (EVD) in Équateur Province, the Democratic Republic of the Congo. Until the outbreak is declared over, intensive surveillance, survivor monitoring and other response activities are ongoing to prevent, promptly detect and respond to potential resurgences of the virus.
No new laboratory-confirmed EVD cases have been detected since the last case developed symptoms on 2 June 2018 (Figure 1). Since the beginning of the outbreak (on 4 April 2018), a total of 38 laboratory confirmed and 15 probable cases (deaths for which it was not possible to collect laboratory specimens for testing) have been reported. Of these 53 cases, 29 died, giving a case fatality ratio of 54.7%. Twenty-eight (53%) cases were from Iboko, 21 (40%) from Bikoro and four (8%) from Wangata health zones (Table 1 and Figure 2). Five healthcare workers were affected, of which two died.
An additional eleven suspected EVD cases have been reported since our last report on 3 July 2018 (External Situation report 14). As of 9 July, five suspected cases are currently awaiting laboratory results. All other previously reported suspected cases have tested negative.
The last surviving confirmed EVD case was discharged from an Ebola treatment centre (ETC), following two negative tests on serial laboratory specimens, on 12 June 2018. Before the outbreak can be declared over, a period of 42 days (two incubation periods) following the last possible exposure to a confirmed case must elapse without any new confirmed cases being detected.
