The World Health Organization (WHO) is preparing for a possible cholera outbreak in the destroyed city of Mariupol, the UN Office for the Coordination of Humanitarian Affairs tweeted on June 9, quoting WHO spokeswoman Margaret Harris.
"In Mariupol, the extensive damage to water systems has mixed water with sewage," Harris said.
"We are concerned about the risk of cholera and have positioned cholera treatment and vaccination supplies in the area."
Mariupol Mayoral Advisor Petro Andriushchenko on June 6 announced that the Russian invaders had begun to quarantine parts of Mariupol due to the spread of cholera in the city.
Ukraine's Health Ministry also warned about the risk of a cholera outbreak.
Mariupol was under siege by the Russian invaders for almost three months. Russia's actions led to a large-scale humanitarian catastrophe, as the invaders bombed residential areas and civilian infrastructure, as well as continually blocking humanitarian aid.
At least 25,000 civilians have been killed by the Russians, Ukrainian authorities estimate
Mariupol Mayor Vadym Boichenko said that the city might face an infectious diseases disaster due to water shortages.
According to him, over 10,000 people may die by late 2022.
