n As of the November 12 World Health Organization update, a total of 564 health-care workers have been infected with the deadly Ebola virus, 320 of whom have died.
n A critical aspect of the response to the Ebola outbreak is the prompt and accurate diagnosis of cases.
n All Ebola-affected districts are
reported to have laboratory support. 13 laboratories have the capacity to confirm Ebola cases - five in each of Liberia and Sierra Leone, and three in Guinea. These
laboratories serve 24 affected districts in Guinea, 15 in Liberia and 14 in Sierra Leone.
n Between 1,150 and 1,170 samples are tested daily in laboratories in the three countries. The maximum testing capacity for each laboratory ranges from 50 to 300 samples per day.
n Effective contact tracing ensures registered contacts of confirmed Ebola cases are identified and visited daily to monitor the onset of symptoms during the 21-day incubation period. Contacts presenting symptoms should be promptly isolated to prevent further disease transmission.
