The World Health Organization (WHO) is preparing for the spread of cholera and other infectious diseases in the occupied territories, WHO's Ukraine Incident Manager Dorit Nitzan has said at a press conference on Tuesday. "We received information from non-governmental organizations that there [in Mariupol] there is a swamp on the streets, and sewage is mixed with drinking water. This increases the possibility of the spread of various diseases, including cholera. We are preparing anti-cholera kits, vaccines and are working closely with non-governmental organizations to support people in the occupied territories," Nitzan said.
