In an address to the nation on Monday (May 31), Prime Minister Lee Hsien Loong outlined Singapore's adjusted strategy to keep Covid-19 under control in the light of new and more infectious strains of the virus.

More liberal and extensive testing is one part of the prime minister's three-pronged strategy. The other two parts of the strategy are faster and wider contact tracing to isolate close contacts more quickly, and an accelerated national vaccination programme that prioritises first-dose vaccinations.

Professor Teo Yik Ying, dean of the Saw Swee Hock School of Public Health, shares his thoughts on these new developments.
