In July 2020, the singer fell ill with symptoms from COVID-19 and was admitted to a hospital in Minsk. Koldun's hospitalisation attracked large media attention in both Belarus and Russia. A few days prior to his hospitalisation, he had performed an opening of a water fountain that was also attended by the president, who was under criticism over his handling of the COVID-19 pandemic. The Belarusian Ministry of Health announced via a statement that Koldun did not have the virus, while Koldun later said in the media that he had tested positive.
