An Ebola survivor ties a ribbon to a "Survivor's Tree" in Port Loko, Sierra Leone, in 2015. When patients tested negative for Ebola and were discharged from treatment, they tied ribbons to the tree to celebrate and to show their communities they were no longer sick or contagious. Researchers who treated Ebola-infected children in Sierra Leone have developed a set of guidelines aimed at improving the treatment of children with Ebola. Such children, particularly those under age 5, faced a high risk of death in the outbreak.
