A child infected by cholera epidemic is treated at a hospital in Sanaa, Yemen, on Aug. 4, 2018. An increasing number of cholera-effected cases in several heavily populated areas over the past few weeks indicates that Yemen may be on the brink of a new cholera epidemic, with a heightened death rate due to widespread malnutrition, and the United Nations is hoping for a ceasefire in the north to allow for vaccinations, the World Health Organization said on Friday.
