WHO has published its weekly update: Ebola virus disease – Democratic Republic of the Congo. Excerpt:
The Ebola virus disease (EVD) outbreak in North Kivu and Ituri provinces in the Democratic Republic of the Congo continued this week with similar transmission intensity to recent weeks, with an average of 81 cases per week (range 68 to 91 cases per week) in the past six weeks (Figure 1). There are currently no confirmed cases of EVD outside of the Democratic Republic of the Congo.
This week, initial data from a randomized clinical trial (RCT) of EVD therapeutics were announced. The data showed that two of the four treatments trialled were more effective in treating EVD. As a result, patients in the four Ebola treatment centres that participated in the RCT will now be randomized to receive the two better performing treatments. Patients in treatment centres not participating in the RCT will continue to be able to access those treatments under a compassionate use protocol. This change will help ensure that every treatment centre patient receives the best possible treatment with the greatest chance of survival, based on the most recent evidence.
The data indicates that when people are willing and able to access care soon after the onset of symptoms, they have an increased chance of survival. Providing each patient with optimal supportive care, closely monitoring their progress, and addressing any other health issues has saved lives and will continue to be a top priority. More information is available in the following update and press release.
No new confirmed cases have been reported in Goma city since our last report, with a total of four confirmed cases reported from Goma (n=1) and Nyiragongo (n=3) health zones to date. Two cases, who were infected via direct contact with the case reported on 30 July, received treatment at an Ebola Treatment Centre in Goma city and were discharged on 13 August. A total of 203 contacts of the Nyiragongo cases remain under surveillance.
In the 21 days from 24 July through 13 August 2019, 66 health areas within 17 health zones reported new cases (Table 1, Figure 2). During this period, a total of 228 confirmed cases were reported, with the majority coming from the health zones of Beni (42%, n=96) and Mandima (20%, n=46). A case was confirmed in Lolwa Health Zone, which is the first confirmed case in that health zone to date, bringing the total number of affected health zones over the course of the outbreak to 27. The case travelled from Mandima to Lolwa, where they became symptomatic. Currently, there is no evidence of local transmission of EVD in this health zone. Close identification and follow up of contacts is ongoing to minimize the chance of local transmission.
New infections continue to be reported among personnel working in community health posts and other facilities. In the last 21 days, 11 new cases were reported among health workers from Beni (n=3), Mandima (n=2), and one each in Katwa, Mabalako, Mambasa, Masereka, Mutwanga, and Vuhovi. Cumulatively, 151 (5%) health workers have been infected to date.
As of 13 August, a total of 2842 EVD cases were reported, including 2748 confirmed and 94 probable cases, of which 1905 cases died (overall case fatality ratio 67%). Of the total confirmed and probable cases, 57% (1608) were female, and 29% (815) were children aged less than 18 years.
