FREETOWN, Sierra Leone -- Sierra Leone is planning another three-day, countrywide shutdown March 27 through 29 to ferret out Ebola cases, remind people how to protect themselves from the disease and control its transmission.

The West Africa Ebola outbreak that has killed more than 10,000 people is declining but the disease has remained stubbornly entrenched in parts of Guinea and Sierra Leone. Liberia, the third country severely affected, currently has no Ebola cases.

In what Sierra Leone hopes will be a final push to zero cases, Alfred Palo Conteh, head of the country's Ebola response, said Wednesday that the government will again ask residents to stay in their homes for three days.

The government has done this before, and some experts said it was unexpectedly effective in providing information about to control the disease.
