WHO: Ebola Spread May Be Slowing in Sierra Leone

GENEVA — 

Sierra Leone, the country worst affected by Ebola, reported nearly 250 new confirmed cases in the past week, but the spread of the virus there may be slowing, the World Health Organization said Wednesday.

The epidemic has taken 8,235 lives out of 20,747 known cases worldwide over the past year, it said.

The WHO's weekly report was based on figures reported by authorities in nine countries. Guinea, Liberia and Sierra Leone account for the majority of infections and fatalities.

"There are signs that case incidence may have leveled off in Sierra Leone, although with 248 new confirmed cases reported in the week to 4 January 2015, it remains by far the worst-affected country at present," the WHO said.

Cases are still underreported and unevenly spread in West Africa. The virus is spreading most rapidly in western Sierra Leone, where the capital, Freetown, reported 93 of the new confirmed cases, the WHO said.

"An increasing emphasis will be put on the rapid deployment of smaller treatment facilities to ensure that capacity is matched with demand in each area," the WHO said.

In Guinea, whose capital, Conakry, remains the worst-affected district, the western prefecture of Fria reported its first Ebola cases.

In Liberia, cases dropped from a peak of more than 300 new confirmed cases per week in August and September to eight new confirmed cases and 40 probable cases in the five days to January 2, it said.

Overall, 838 health workers have been infected, and 495 have died, the WHO said.

On Thursday, the WHO will host a meeting of representatives from major drugmakers, health authorities in affected countries and national regulatory agencies to assess clinical trials of experimental vaccines against Ebola. GlaxoSmithKline, Merck and NewLink Genetics, and Johnson & Johnson are currently testing experimental vaccines.
