Control of VHF Ebola in West Africa is complicated by the fact that we know so little as to the mechanisms for the spread of the disease other than direct contact with infected persons or their bodily fluids, which local wildlife and rodents actually serve as hosts for the virus and the actual survivability of viable Ebola virus on fomites.   Given these knowledge gaps, modeling the spread and control of the disease with any probability of being close to reality is unlikely.    Potentially, these gaps suggest that the current focus on treatment and traditional control protocols have be insufficient to stop the outbreak and produce an Ebola free West Africa.

Lagos --With quick and coordinated action by some of its top doctors, Nigeria, Africa’s most populous country, appears to have contained its first Ebola outbreak, the United States Centers for Disease Control and Prevention said Tuesday.

As the epidemic rages out of control in three nations only a few hundred miles away, Nigeria is the only country to have beaten back an outbreak with the potential to harm many victims in a city with vast, teeming slums.

“For those who say it’s hopeless, this is an antidote — you can control Ebola,” said Dr. Thomas R. Frieden, director of the C.D.C.   ....

WASHINGTON - The rainy season in West Africa is compounding difficulties in getting supplies delivered and new treatment centers built as donors rush to isolate people infected with the deadly Ebola virus and stop its rapid spread, U.S. officials said.

Nancy Powell, newly appointed as the U.S. State Department's envoy to coordinate its Ebola response, said the top priority is to isolate as many people as quickly as possible. But that faces significant logistical hurdles.

"Infrastructure challenges in the rainy season is one of the biggest difficulties. And you add the rain and getting materials out of the capital and it is very difficult," Powell said in a news briefing last week.

The July to September rainy season is coming toward its end, but October is known for heavy thunderstorms that can drench the region and turn roads to mud.

Eric Talbert, executive director of Emergency USA which has opened a 22-bed Ebola treatment center in Goderich, outside the capital of Freetown in Sierra Leone, said the downpours complicate getting supplies along unpaved single track roads that are washed out by the heavy rains..
