ACCRA, Ghana (Bloomberg) - Liberia, the West African nation where Ebola killed the most people in the largest outbreak of the virus, has been declared free of the disease by the World Health Organization.

The notification by the Geneva-based WHO was received today, Liberia's Ministry of Information said on its Twitter account Saturday. No new Ebola cases have been detected since the burial of the last victim 42 days ago, twice the incubation period.

"We are out of the woods. We are Ebola free," the ministry said. "Thanks to our partners for standing with us in the fight against Ebola."

The disease is still spreading in Sierra Leone and Guinea, though at a slower pace, encouraging the government efforts there to control the outbreak, which started in December 2013.

More than 10,000 people have died, with about half of them in Liberia.

The three nations had about 500 doctors at the start of the outbreak and struggled to contain the disease amid a lack of medical infrastructure, decades of devastation from civil wars and shortages of medical personnel.
