Olena Zelenska, the wife of Ukrainian President Volodymyr Zelensky, said on Friday she had tested positive for coronavirus, but her husband and their two children had tested negative.
Zelenska, 42, on her Facebook page said, “Today I’ve received a positive COVID-19 test result”.
She said the positive test was a surprise as she and her husband have sought to follow social distancing rules and protected themselves.
The first lady said that she felt fine and was self-isolating.
Ukrainian officials said it is unknown where and how the first lady contracted the virus.
On Thursday, Ukrainian authorities said there had been an “alarming” rise in coronavirus cases as the country eases lockdown restrictions.
On Friday, the ex-Soviet country reported 29,753 cases and 870 fatalities.
The Ukrainian president urged officials to urgently establish the reason behind a spike in new cases.
