The World Health Organization has posted their updated Ebola Roadmap, showing an increase of more than 1,200 cases since last week’s report, and 381 additional deaths. The number of HCWs infected has increased by 30 as well.

A total of 17 145 confirmed, probable, and suspected cases of Ebola virus disease (EVD) have been reported in five affected countries (Guinea, Liberia, Mali, Sierra Leone, and the United States of America) and three previously affected countries (Nigeria, Senegal and Spain) up to the end of 30 November. There have been 6070 reported deaths. Reported case incidence is slightly increasing in Guinea (77 confirmed cases reported in the week to 30 November), stable or declining in Liberia (43 new confirmed cases in the 5 days to 28 November), and is still rising in Sierra Leone (537 new confirmed cases in the week to 30 November). The case fatality rate across the three most-affected countries in all cases with a recorded definitive outcome is 72%; in hospitalized patients the case fatality rate is 60%.
Response activities in the three intense-transmission countries continue to intensify in line with the UNMEER aim to isolate and treat 70% of EVD cases, and safely bury 70% of EVD-related deaths by 1 December, with the ultimate goal of reaching 100% by 1 January. At a national level, there is now sufficient bed capacity in EVD treatment facilities to treat and isolate all reported EVD cases in each of the three countries, although the uneven distribution of beds and cases means there are serious shortfalls in some areas. Similarly, each country now has sufficient and widespread capacity to bury all reported EVD-related deaths; however, because not all EVD-related deaths are reported, and many reported burials are of non-EVD-related deaths, it is possible that the 70% target has not been met in some areas. Every EVD-affected district in the three intense-transmission countries has access to a laboratory for confirmation within 24 hours of sample collection. All three countries report that more than 85% of registered contacts associated with known cases of EVD are being traced, although contact tracing is still a challenge in areas of intense transmission. Increasing capacity for contact tracing in areas with low levels of transmission will be necessary to end local chains of transmission.
A total of 622 health-care workers (HCWs) are known to have been infected with EVD up to the end of 30 November, 346 of whom have died (table 5). The total case count includes 2 HCWs in Mali, 11 HCWs infected in Nigeria, 1 HCW infected in Spain while treating an EVD-positive patient, and 3 HCWs in the US (including a HCW infected in Guinea, and 2 HCWs infected during the care of a patient in Texas).
