A new wave of cholera is expected in March or April. “It’s probably unavoidable. We need to be ready to face another big epidemic,” said Poncin, adding that cholera may become a long-term burden as it has in Haiti. “The places where the war is active are the ones most at risk for increase of disease.” The latest emergency is diphtheria, a disease not seen in Yemen for 25 years, which has affected 312 people and killed 35. It has not spread explosively, as cholera did, but diphtheria outbreaks can affect many thousands, and there is a global shortage of diphtheria anti-toxin. Yemen has enough for 200-500 patients, Poncin said.
