Nearly one million children across eastern and southern Africa are suffering from “severe acute malnutrition” after two years of drought and the strongest El Nino in 50 years, UNICEF said Wednesday. Children in the region face food and water shortages, with rising prices worsening the situation as families are forced to skip meals and sell belongings. “Severe acute malnutrition” is defined as extreme hunger, causing a very low weight-for-height ratio, visible wasting or fluid retention.
