The last known Ebola patient of Guinea, a 19 day old baby, has recovered and was released from the treatment center in the capital Conakry, a health official said on Monday.
If no new case is reported within six weeks, the country will be declared free of Ebola.
Neighbouring Sierra Leone and Liberia were declared free on November 7 and entered a 90 day period of heightened surveillance.
The baby was born in the Ebola treatment centre, but the mother did not survive the disease.
"We did two tests after his treatment and they came back negative," Fode Tass Sylla, spokesman for Guinea's Ebola coordination unit said.
Guinea is the latest West African country that is suffering from the Ebola outbreak that began in March 2014.
Since then, more than 28,000 people were diagnosed or suspected of Ebola and over 11,000 died, according to the World Health Organization (WHO) reports.
Some 2,500 of them died in Guinea.
The numbers are expected to be higher though, given the difficulty of collecting data.
