WHO has published Ebola virus disease update - west Africa. Click through for the full statement and a table of cases. Excerpt:
Between 10 and 11 August 2014, a total of 128 new cases of Ebola virus disease (laboratory-confirmed, probable, and suspect cases) as well as 56 deaths were reported from Guinea, Liberia, Nigeria, and Sierra Leone.
Contact tracing in Guinea, Nigeria, and Sierra Leone has resulted in a range between 94% and 98% of contacts of EVD cases being identified and followed-up. In Liberia, efforts are underway to strengthen contact tracing, but help is needed in this area. The Liberian Army has also recently placed a third province under quarantine as part of the ongoing effort to stop transmission of EVD.
According to WHO, Nigeria now has 12 cases and three deaths. It's hard to find consistent numbers in the Nigerian media.
