The World Health Organization has released their latest weekly Ebola situation report, and while case counts and death tallies are still believed to be under-counted, they report that the number of new cases appears to be stable or declining in Liberia and Guinea, but may be rising again in Sierra Leone.
The toll on healthcare workers continues to run high, with nearly 600 infected, and 330 deaths. Follow the link below ro read the full update online, or Download the PDF
A total of 15 935 confirmed, probable, and suspected cases of Ebola virus disease (EVD) have been reported in six affected countries (Guinea, Liberia, Mali, Sierra Leone, Spain and the United States of America) and two previously affected countries (Nigeria and Senegal) up to the end of 23 November. There have been 5689 reported deaths. Cases and deaths continue to be under-reported in this outbreak. Reported case incidence is stable in Guinea (148 confirmed cases reported in the week to 23 November), stable or declining in Liberia (67 new confirmed cases in the week to 23 November), and may still be rising in Sierra Leone (385 new confirmed cases in the week to 23 November). The total number of cases reported in Sierra Leone since the outbreak began will soon eclipse the number reported from Liberia. The case fatality rate across the three most-affected countries in patients with a recorded definitive outcome is approximately 60%. Three health-care workers were reported infected with EVD in Guinea in the week to 23 November.
Response activities continue to intensify in line with the UNMEER aim to isolate 70% of EVD cases and safely bury 70% of EVD-related deaths by 1 December. Guinea isolates over 70% of all reported cases of EVD, and has more than 80% of required safe burial teams. Progress on isolation and safe burials has apparently been slower in parts of Liberia and Sierra Leone, although uncertainties in data preclude firm conclusions. At a national level, both countries are apparently unable to isolate 70% of patients, although data on isolation is up to 3 weeks out of date. Every EVD-affected district in the three intense-transmission countries has access to a laboratory for case confirmation within 24 hours of sample collection. All three countries report that more than 80% of registered contacts associated with known cases of EVD are traced, though the low mean number of contacts registered per case suggests that contact tracing is still a challenge in areas of intense transmission.
A total of 592 health-care workers (HCWs) are known to have been infected with EVD up to the end of 23 November, 340 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).
