Emergencies preparedness, response

The intensity of Ebola virus disease (EVD) transmission in the North Kivu, South Kivu, and Ituri provinces remains substantial, with 57 new cases reported since the last EVD in the Democratic Republic of the Congo Disease Outbreak News Update on 29 August. While hotspots such as Beni Health Zone show signs of easing, new hotspots are emerging elsewhere. During the past 21 days, from 14 August through 4 September 2019, a total of 186 confirmed cases were reported, with the majority coming from the health zones of Beni (17%, n=31), Kalunguta (15%, n=28), Mandima (13%, n=24), and Mambasa (12%, n=22). Given the limited access and insecurity in the emerging clusters within Kalunguta, Mandima, and Mambasa health zones, the response activities have been somewhat hindered.

Likewise, sustained local transmission in Mutwanga and Kayna health zones, on the shores of Lake Edward and Ugandan border, pose added risks of regional spread. This risk was highlighted last week by the confirmation of a case on 29 August in a young child who was exposed and developed symptoms in Mutwanga Health Zone before she was identified at the Mpondwe-Kasindi border point of entry (PoE) when travelling with her mother to seek medical care. The child was immediately transported to an Ebola Treatment Centre (ETC) in Bwera, Uganda, where she was provided with care but unfortunately died shortly after arrival. While a limited number of potential contacts are currently under surveillance, there have not been any further cases confirmed in Uganda to date.

As of 4 September, a total of 3054 EVD cases were reported, including 2945 confirmed and 109 probable cases, of which 2052 cases died (overall case fatality ratio 67%). Cases have been reported from 29 health zones since the beginning of this outbreak, of which 17 health zones reported new cases in the last 21 days (Table 1, Figure 2). Of the total confirmed and probable cases, 58% (1772) were female, 28% (865) were children aged less than 18 years, and 5% (156) were health workers.

Under Pillar 1 of the current Strategic Response Plan, the estimated funding requirement for all partners for the period July to December 2019 is US$ 287 million, including US$ 120-140 million for WHO. As of 6 September 2019, US$ 45.3 million have been received by WHO, with further funds committed or pledged. Current available funds will close the financing gap up until the end of September 2019. Further resources are needed to fund the response through to December 2019, and WHO is appealing to donors to provide generous support. A summary of funding received by WHO since the start of this outbreak can be found here.
