Liberia was declared free of the Ebola virus by global health experts on Thursday, a milestone that signaled an end to an epidemic in West Africa that has killed more than 11,300 people.
Experts said progress had been made in the region's response to Ebola, with new cases having dwindled due to public health campaigns, efforts to trace and isolate potential sufferers and the safe treatment and burial of patients and victims.
Hundreds of healthcare workers in both urban and rural communities were among those killed by the disease, a major blow to medical systems in countries which already had among the lowest numbers of doctors per head of population in the world.
"Today's WHO announcement is welcome news but we must learn from Ebola's devastating impact and ensure we are better prepared for infectious disease outbreaks," said Dr Seth Berkley, head of Gavi, the Vaccine Alliance, an organization that aims to increase access to vaccines in poor countries.
