At least five people have died since 29 February 2016 due to a new flare up of Ebola virus disease (EVD) in Guinea [1]. The first two confirmed cases of the virus were detected in the village of Korokpara and involved a mother and her five-year-old son. These are the first cases of Ebola in Guinea since the World Health Organization (WHO) declared the country free of the disease in December 2015. This declaration came two years after an outbreak that began in 2013 killed approximately 2,500 people in Guinea and over 11,000 in West Africa [2]. The WHO had warned that Guinea, as well as the neighboring countries of Liberia and Sierra Leone, are at risk for ongoing smaller outbreaks due to persistence of the virus in some previously infected individuals [3]. Guinea’s 90-day heightened surveillance period was set to end in late March [4].

29 March 2016 – The United Nations World Health Organization (WHO) today said West Africa's Ebola outbreak no longer constitutes an international public health threat, declaring that the 20-month global emergency response is over but stressing that a “high level of vigilance” must be maintained.

Life is returning to normal in Guinea, Liberia and Sierra Leone, after the worst Ebola outbreak in history took 11,000 lives. International medical teams have packed up their bags and left. The world has shaken off its Ebola jitters, but now scientists at Fred Hutchinson Cancer Research Center and colleagues from China and Sierra Leone are conducting a kind of extended postmortem, trying to figure out what happened.
