There were celebrations in Sierra Leone Saturday as the World Health Organization declared the country free of Ebola transmissions - but it remains under heightened surveillance for a further 90 days.
Nearly 4,000 people have died in Sierra Leone in the worst Ebola outbreak in history, NBC News reported.
Weak leadership, shoddy supplies and infighting worsened the battle against this outbreak of the virus that has killed some 11,000 people mainly in Guinea, Sierra Leone and Liberia, and WHO has been criticized for its response.
The organization said that 42 days have passed — twice the maximum incubation period — since the last confirmed Ebola patient was discharged Sept. 25.
