Ebola Virus Disease - Democratic Republic of the Congo: External Situation Report 28 (01 July 2017)
Date of information: 30 June 2017
1. Situation update
The Ebola virus disease (EVD) outbreak in Likati Health Zone, Bas Uele Province in the north east of the country remains stable. As 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 ensure the outbreak remains controlled, planning is also underway to declare the end of the outbreak on 2 July 2017.
Since our last update on 27 June, no new confirmed, probable or suspected cases have been reported. Two alerts were reported between 27 June and 28 June. One alert was from Mobenge and the other, a community death in Tobongisa, was considered a suspected case. All the alerts and the suspected cases were subsequently discarded following further investigation.
Cumulatively, since the start of the outbreak, there have been five confirmed and three probable cases. The last confirmed case was isolated on 17 May 2017 and tested negative for EVD by PCR for the second time on 21 May 2017. Of the confirmed and probable cases, four survived and four died, resulting in a case fatality rate of 50%. The confirmed and probable cases were reported from Nambwa (three confirmed and two probable), Muma (one probable), Ngayi (one probable) and Mabongo (one confirmed).
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. A response team will remain in the affected areas until the declaration of the end of the outbreak.
The declaration of the end of the outbreak is expected on 2 July following a 42 day period since the last confirmed case tested negative for the second time. The 42 day period is twice the maximum incubation period for Ebola and is used to confirm the interruption of human to human transmission of the disease. Following this period enhanced surveillance will continue for 90 days together with heightened infection, prevention and control measures.
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.
