Ebola Virus Disease - Democratic Republic of the Congo: External Situation Report 21 (05 June 2017)
1. Situation update
WHO, UN Agencies, international organizations, non-governmental organizations (NGOs) and partners continue to support the Ministry of Health (MoH) in the Democratic Republic of the Congo to rapidly investigate and respond to the outbreak of Ebola virus disease (EVD) in Likati Health Zone, Bas Uele Province in the north-east of the country.
On 05 June 2017, one case has been retrospectively confirmed as positive for EVD by serology with a date of onset of 29 April 2017. This case was previously reported as a suspected case and is part of the known transmission chain. The contacts for this individual have already been followed up and graduated from the contact follow up period. The date of the last confirmed case reported remains as 11 May 2017.
One new suspected case has been reported as of 5 June 2017 in the Ngayi health area, with 15 associated contacts being followed up daily, a sample has been taken to test for EVD. Therefore there are currently a total of five confirmed, three probable and one suspected case. Of these, four survived and four died, resulting in a case fatality rate of 50%.
The confirmed and probable cases were reported from Nambwa (four confirmed and two probable), Ngayi (one probable) and Mabongo (one confirmed). The outbreak remains confined to Likati Health Zone. Modelling suggests the risk of further cases is currently low but not negligible, and decreases with each day without new confirmed/probable cases. As of the reporting date, 76% of simulated scenarios predict no further cases in the next 30 days.
All seven response committees are maintaining functionality at the national level, namely monitoring, case management, water sanitation and hygiene (WASH) and biosafety, laboratory and research, pyscho-social management, logistics, and communication. The first response teams who have been in the field since the start of the outbreak and being replaced this week. A response team will remain in the affected areas until the declaration of the end of the outbreak.
This EVD outbreak in the Democratic Republic of the Congo was notified to WHO by the MoH on 11 May 2017. The cluster of cases and deaths of previously unidentified illness had been reported since late April 2017. Likati Health Zone shares borders with two provinces in the Democratic Republic of the Congo and with the Central African Republic (Figure 1). The affected area is remote and hard to reach, with limited communication and transport infrastructure.
