"After experiencing light symptoms, my wife and I tested positive for COVID-19. We have a mild infection thankfully, which we learned to be the Omicron variant," the 67-year-old president said in a tweet.

"We remain on duty. We will continue our work from home. We hope for your prayers," Erdogan added.

"God willing we will shake this infection off together with Mr Tayyip," his 66-year-old wife, Emine Erdogan, tweeted.

The Turkish president received his third vaccine dose in June last year.

Later during the day, Pakistan Prime Minister Imran Khan on Saturday wished Tayyip Erdogan a swift and complete recovery after he had tested positive for COVID-19.

"The result of Covid-19 tests done with my wife after showing mild symptoms came back positive," Erdogan said in a tweet, adding that both had the Omicron variant of the virus.

"I just learnt that my brother Recep Tayyip Erdogan, President of Turkey and Madame Emine Erdogan tested positive for Covid-19 Omicron," the premier wrote on his official Twitter handle.

"On behalf of our government, the people of Pakistan and on my own behalf I wish them a swift and complete recovery."

Officials of his AKP ruling party, ministers and opposition leaders also wished him a speedy recovery.

Turkey has recorded around 12 million cases of Covid-19 and nearly 90,000 deaths since the start of the pandemic.

Turkey requires people to isolate for seven days if they test positive. However if they test negative on the fifth day, they can leave quarantine.

The country's daily number of cases has risen to over 100,000 in recent weeks, which officials have attributed to the highly contagious Omicron variant.

Masks are widely used in Turkey but there are no restrictions with schools and universities still open, and life continuing as normal without curfews.

The latest official figures on Saturday showed 52.5 million have had their second vaccine dose in Turkey, which has a population of around 85 million.

More than 25 million Turks have also got their third dose and officials continue to push for citizens to get vaccinated.
