Guinea was declared free of Ebola transmission on Tuesday after more than 2,500 people died from the virus in the West African nation, leaving Liberia as the only country still counting down the days until the end of the epidemic.
The announcement made at a ceremony in the capital comes 42 days after the last Ebola patient tested negative for a second time. The country now enters a 90-day period of heightened surveillance, the U.N. World Health Organization said.
The world's worst Ebola outbreak began in Gueckedou, eastern Guinea, in December 2013 before spreading to Liberia, Sierra Leone and seven other countries. In all, more than 11,300 people died, almost all in the three worst-affected nations.
