The Ebola epidemic in eastern DR Congo continues to gain ground, with an increase in the number of cases and a spread to new geographic areas, the WHO warned on Friday. This resurgence of hemorrhagic fever revives memories for Liberian Dr Jerry Brown, on the front line in the fight against the virus during the epidemic which struck West Africa between 2013 and 2016. "Ebola knows no borders", recalls the doctor, who hopes for more international mobilization.
