After losing more than 4,000 people to Ebola, Liberia has now been declared by the World Health Organization (WHO) to be free of the disease.
Ebola has killed more than 10,000 people in Guinea, Liberia and Sierra Leone, and the United Nations says those numbers are vastly under-reported.
Liberia has gone without a new case for 42 days, twice the maximum incubation period, which is why it's now deemed free of Ebola.
Guinea and Sierra Leone each had nine new cases last week, a dramatic decline from last fall when each week saw hundreds of new cases.
Three reasons are often given for this poor initial response:
Ebola hit big cities, where people live in close quarters;
The West African countries have a dangerous lack of doctors, nurses, laboratories and supplies;
Lastly, it was difficult to convince people to put a halt to the tradition of washing their dead relatives before burial, which spread the virus.
There is no cure for the virus and no vaccine, but care from medical workers so far has helped sustain the lives of nearly half of those stricken.
