Medics in Guinea were on Friday racing to track down suspected carriers of the Ebola virus, after they fled a southeastern town where the country’s first case in nearly a month was detected the previous day. The case followed a “cluster of suspicious deaths” in Soulouta, the West African country’s World Health Organization (WHO) representative, Georges Alfred Ki-Zerbo, said. “This illustrates the need for enhanced monitoring in the (local) ...region, but also in other regions ...to contain this new cluster as soon as possible,” he told Reuters. After the case was diagnosed, some residents initially barricaded roads into the town, denying access to response teams who were now searching for other suspected Ebola cases who had fled, local officials said. The case in Soulouta, less than 20 kilometers (12 miles) from where an ongoing Ebola outbreak began in February, reset a count that had begun last week to declaring the country free of the virus. A total of 15 people have tested positive for Ebola and nine have died during the current outbreak. It marked the first resurgence of the virus in Guinea since its deadliest epidemic, which killed more than 11,000 people in Guinea, Liberia and Sierra Leone between 2013 and 2016. An Ebola outbreak is typically declared over once 42 days have passed following a second negative test of blood samples from the last confirmed case. Guinea began a vaccination campaign to contain the spread of the virus, which causes severe bleeding and organ failure and is spread through contact with body fluids, at the end of February. The WHO said in March that the February resurgence is likely to have been sparked by a latent infection in the human population from the last Ebola outbreak rather than from the virus jumping the species barrier again. The Organization was on high alert, “supporting Guinean health authorities’ surveillance efforts and preparedness in neighbouring areas,” its regional head for Africa, Matshidiso Moeti, said on Twitter.
