The co-chairs of the ministerial task force tackling the pandemic - Health Minister Gan Kim Yong and Education Minister Lawrence Wong - will hold a press conference immediately after, he said in a Facebook post.
"It's been some time since my last address on Covid-19," Lee wrote. "But please stay calm - no need to stock up on anything!"
Since last month, the pandemic is well under control in the Republic. Local cases have been getting lesser and lesser. Reported cases were also mostly imported cases and were all in single digits.
On Sunday (Dec 13), there were seven new coronavirus cases confirmed at noon taking Singapore's total to 58,320.
All were imported cases who had been placed on stay-home notices on arrival in Singapore.
No cases from the community or within worker dormitories were announced on Sunday by the Ministry of Health (MOH).
It was almost similar on Saturday (Dec 12). On Saturday, eight new coronavirus cases were reported.
All were imported cases who had been placed on stay-home notices or isolated on arrival in Singapore, said MOH.
Saturday's cases included five Singaporeans and one Singapore permanent resident who had returned from Nepal, Britain and India.
Over the course of this year, PM Lee has made several major speeches laying out Singapore's plan to tackle the Covid-19 pandemic.
In his first such address on Feb 8, he urged Singaporeans to stay resolute in the face of what was then a new and relatively unknown virus.
Just over a month later, he warned that more stringent measures might have to be taken, as the pandemic looked set to continue for some time.
This was followed by his announcement of the circuit breaker on April 3. All schools and most workplaces were shut, with social interactions and movement outside the home severely limited in an effort to stop the spread of the virus.
Lee added a special appeal to seniors several days later, urging them to stay home for their own safety.
On April 21, the Prime Minister then announced that the circuit breaker would be extended as total case numbers continued to climb, especially in migrant worker dormitories.
Lee, along with Senior Ministers Teo Chee Hean and Tharman Shanmugaratnam, as well as Deputy Prime Minister Heng Swee Keat, Trade and Industry Minister Chan Chun Sing and Education Minister Lawrence Wong, also made a series of national broadcasts on Singapore's future post Covid-19.
In June, he also explained why he had decided to call the general election on July 10 despite the pandemic. - The Straits Times/Asian News Network
