Member of the government's scientific council and professor of virology Irja Lutsar told newspaper Postimees the record number of new coronavirus cases reported on Saturday is the combined result of yesterday and previous days' tests which have been unreported.
"The consistent rise in figures was to be expected," Lutsar said, adding the increase was not that sharp.
"A lot of it depends on when the tests are reported. Looking at the time when many of the tests reported today were performed, many of them were taken earlier. For some reasons, a number of tests from the day before yesterday were included in today's statistics. That is what caused the record high number. Figures from the previous days were actually deceptively low and anomalous.
"The total number of infections this week was larger than last week. I believe we should await the effects of the current restrictions, however. Today's numbers are not yet indicative of the efficiency of new restrictions. The new ones have not taken effect just yet," she added.
On Saturday, the Health Board announced that 760 new cases of coronavirus had been diagnosed in the last 24 hours - a new record.
On Friday, the agency said 357 new cases were confirmed in the previous 24 hours, which was much lower than the two days previous which both had more than 500 cases.
