Between 19 and 20 August 2014, a total of 142 new cases of Ebola virus disease (laboratory-confirmed, probable, and suspect cases) as well as 77 deaths were reported from Guinea, Liberia, Nigeria, and Sierra Leone.
Questions have been received in WHO Headquarters about the original proposed budget for the response and the new draft budget, which is being reviewed by partners. The increase in needed resources is based on improved data and understanding of the situation on the ground in the affected countries. The new estimation of costs is derived using a unit-cost model, built for the most intense transmission areas and reflects the average operational costs based on the current situation in the affected countries. The major assumptions for the cost estimates will be announced towards the end of next week.
WHO continues to receive reports of rumoured or suspected cases from countries around the world and systematic verification of these cases is ongoing. Countries are encouraged to continue engaging in active surveillance and preparedness activities. As of today, no new cases have been confirmed outside of Guinea, Liberia, Nigeria, or Sierra Leone.
As of 22 August 2014, the cumulative number of cases attributed to EVD in the four countries stands at 2615, including 1427 deaths. (Article above quotes from WHO)
