He said that he tried to be careful, but the work of the mayor during a pandemic involves constant risk, including communication with people and inspection of hospitals.

"In particular, I regularly visited the infectious diseases wards, where patients with COVID-19 are treated. I tried to be careful. Given the specifics of my work, I regularly did tests. Today's, unfortunately, is disappointing. I feel good. But I have to self-isolate and work from home," Klitschko said.
