The region's Ebola outbreak has killed more than 10,000 people since cases were first recorded more than a year ago, with most of the dead coming from Guinea, Sierra Leone and Liberia.
Sierra Leone, which has seen the most cases, imposed a three-day lockdown that officials hoped would help the country get "total control" over Ebola. The lockdown was expected to conclude today.
Neighboring Guinea could soon be holding its own lockdowns after President Alpha Conde announced that emergency steps would be "reinforced" for a 45-day period in five districts in the west of the country.
Conde also said lockdown measures could be implemented as needed.
In Liberia, the government issued a statement today warning survivors of Ebola to abstain from unprotected sex even beyond the 90-day period earlier recommended. The statement was prompted by continued confusion over how the country's latest Ebola patient its first in weeks came down with the disease.
