On Thursday, the local authorities informed that two people have tested positive for Ebola in Guinea. The confirmation has come months after the outbreak was declared over in the West African country and hours after Sierra Leone declared that the recent flare-up of the virus has come to an end there.

Ibrahima Sylla, spokesman for the national coordination for the fight against Ebola, said that the cases belong to the same family in Koropara, located in the N’Zerekore region, roughly 1,000 kilometers southeast of Conakry, Guinea’s capital.

Sylla said that there are three other likely cases, and health authorities have taken important measures to restrict the spread.

Dr. Sakoba Keita, the national coordinator of the fight against Ebola, said that they are going to hold an emergency meeting on Friday with the Ministry of Health.

Previously on Thursday, the deputy director general of the N’Zerekore Regional Hospital, Dr. Zoba Guilavogui, said a man and a woman belonging to the same family lost their lives from an illness with symptoms similar to Ebola, however, there tests weren’t done.

On December 29, Guinea was declared Ebola free. At the end of this month, the country would be celebrating the end of its 90-day heightened surveillance period.

History’s deadliest Ebola outbreak has taken over 11,300 lives, mainly in Sierra Leone, Liberia and Guinea.

On January 14, the outbreak was declared over by the World Health Organization, when Liberia came at third place among three nations that have announced control over outbreaks. However, the following day, a dead body tested positive for Ebola in Sierra Leone, which was facing a flare-up of another case.

On Thursday, the WHO and Sierra Leone’s Ministry of Health and Sanitation declared the end of that Ebola flare-up. The declaration has come 42 days after the last confirmed Ebola patient tested negative twice.
