Guinea has confirmed two new Ebola cases, 3 months after the end of the outbreak was celebrated.
In the family from which it was confirmed, three members are suspected to have died from it.
The region where the outbreak has been reported is in Nzerekore where the outbreak started in December 2013.
The outbreak has led to the deaths of 11, 300 people, most of them coming from Guinea as well as neighbouring countries of Liberia and Sierra Leone.
The World Health Organization reported the new cases hours after it declared the recent Ebola flare-up to be finalized in Sierra Leone.
This not unexpected occurrence is a major blow to the fight to counter the virus.
The virus was declared on 29th Dec 2015 to be officially over and Guinea was the only country of the three worst affected not to have had a re-emergence.
There have been little clusters of cases reported in Liberia and Sierra Leone after the outbreak was declared to have ended. But they were handled at a faster rate.
A risk of new flare-ups remains because Ebola can persist in body fluids of some survivors for months after they recover.
There are some situations in which the cases were linked to sexual transmission.
Over 17,000 Ebola survivors are coping up with various complications as well as social stigma.
Some scientists say that the virus may turn out to be an everyday disease in West African society.
