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 31 May 2017, no new confirmed, probable or suspected EVD cases were reported. The last confirmed case was reported on 11 May 2017. There are currently a total of two confirmed, three probable and 12 suspected cases.
The confirmed and probable cases were reported from Nambwa (two confirmed and two probable) and Ngayi (one probable). The suspected cases are reported from four health areas (Nambwa, Muma, Ngayi and Ngabatala). The outbreak remains confined to Likati Health Zone. As of 31 May, 29 further contacts completed the monitoring period and did not show signs and symptoms of Ebola, 72 contacts remain under follow up.
The previously undertaken modelling to determine the risk of further cases was updated with newly available onset dates for the five confirmed / probable cases. Results suggest 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 functional at a national level, namely monitoring, case management, water sanitation and hygiene (WASH) and biosafety, laboratory and research, pyscho-social management, logistics, and communication. Additionally response teams have been established in the affected areas.
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.
