The number of Covid-19 cases here has doubled twice since Aug 23 and could double three more times before falling and stabilising, Health Minister Ong Ye Kung said on Friday (Sept 10).
He noted that around 100 cases were reported on Aug 23.
"From then, it's been rising along a very steep curve," Mr Ong said at a virtual press conference of the multi-ministry task force tackling Covid-19.
Mr Ong, who co-chairs the task force, said that based on the experiences of other highly vaccinated countries, Covid-19 transmission waves do not last forever and will usually take about 30 to 40 days to peak before numbers fall and stabilise.
However, during that period, daily cases can double every 10 days - which means Singapore should be prepared for four to five doubling cycles, added Mr Ong.
He said the nation is now in the process of seeing cases double from 400 to 800 a day.
"Beyond that, if we think in terms of five doubling cycles, there's two more to go - meaning daily cases may double from 800 to 1,600 and 1,600 to 3,200, hitting a peak before starting to come down and stabilise," he said, adding that whether or not this happens depends on the collective actions of everyone here.
