The president, 77, leaves the military hospital in Prague and will nominate Petr Fiala as prime minister on Sunday, his office says.
Czech President Milos Zeman leaves a military hospital in the capital Prague after testing positive for the coronavirus.
The 77-year-old had already been discharged after more than a month of treatment for an unspecified illness on Thursday, but was readmitted hours after being diagnosed with COVID-19.
Zeman received monoclonal antibodies, a standard treatment for people belonging to risk groups. She has been fully vaccinated against COVID-19 including a booster. The hospital said the president has no symptoms of the disease.
On 10 October, a day after the parliamentary election, he was taken to hospital and treated in the intensive care unit. His condition was attributed to an unspecified chronic illness.
A heavy smoker and drinker, Zeman, who suffers from diabetes, has trouble walking and is using a wheelchair.
The presidential office said on Saturday that Zaman was planning to swear in Petr Fiala, the leader of the election-winning coalition, as the country’s new prime minister on Sunday.
The ceremony was due to take place on Friday, but was put on hold by the president’s new hospitalization.
The office said the ceremony would be held in line with current coronavirus measures, but details were unknown. Those who test positive will have to isolate in the Czech Republic for two weeks.
The country is facing a record surge in a new wave of infections. The new daily increase hit a record high of nearly 28,000 cases on Thursday. The infection rate was 1,207 new cases per 100,000 residents in the past seven days.
Overall, the country of 10.7 million has registered over 2.1 million cases with 32,744 deaths.
