Singapore’s Prime Minister Lee Hsien Loong tested positive for COVID-19 again on Thursday (Jun 1) due to a “COVID rebound”.
He had first tested positive for COVID-19 on May 22. Last Sunday, he said he was COVID-19 negative and would return to work.
“I feel fine but I am afraid I have turned COVID-19 positive again,” said Mr Lee in a Facebook post on Thursday.
“My doctors say it is a COVID rebound, which happens in 5 to 10 per cent of cases.”
The Prime Minister, who is 71, added that he is still infectious although the risk is not high compared to the initial infection. He said his doctors have advised him to isolate himself until he tests negative using an antigen rapid test (ART).
Mr Lee tested positive for COVID-19 for the first time on May 22 following his visits to South Africa and Kenya. He was prescribed the antiviral medication Paxlovid because of his age.
In a Facebook post on May 28, he wrote that he was COVID-19 negative and would be back to work on Monday.
The US Centers for Disease Control and Prevention (CDC) issued a health advisory in May last year about the potential for the recurrence of COVID-19 or COVID rebound.
It said a brief return of symptoms may be part of the “natural history” of COVID-19 in some people, independent of treatment with Paxlovid and regardless of vaccination status.
A COVID rebound has been reported to occur between two and eight days after initial recovery and is characterised by a recurrence of COVID-19 symptoms or a new positive viral test after having tested negative.
Mr Lee said on Thursday that he had looked forward to attending the consecration ceremony of Sri Thendayuthapani Temple but will now have to miss it as he is isolating.
“My apologies to the organisers, and to all those attending the ceremony. I wish everyone a very successful consecration and celebration,” he said.
