One of every 200 people in Yemen suspected of having cholera. As of July, the number of cholera cases in Yemen had exceeded 300,000, with more than 1,700 deaths, according to the International Committee of the Red Cross. Distribution of aid by the World Health Organization (WHO) and others has been hampered by the ongoing civil war and the collapse of the Yemen health care system. The WHO estimated in July that the flow of medicines had decreased by 70%. The United Nations, meanwhile, has suspended plans for a cholera vaccination campaign because of inadequate access to areas threatened by the epidemic.
