Survivors including health and aid workers recall their experiences and lessons during the 2018-2020 Ebola outbreak in eastern Congo. The outbreak, history’s second-biggest with more than 3,400 reported cases and over 2,200 deaths, was stopped with the aid of vaccines. In Beni, a bustling commercial hub near the borders with Uganda and Rwanda, some fear that a repeat of mistakes made at the time and the lack of an approved vaccine might make the response to the current outbreak more challenging. A total of 550 cases of the disease were confirmed as of Sunday in the current outbreak caused by the rare Bundibugyo virus, which can cause Ebola disease, including 101 deaths and 19 recoveries.
