The Delta variant, which accounted for 0.01 percent of cases in the third week of March, was not found at all last week.
The daily tally of new infections stood at 347,554 as of Tuesday morning, with 1,215 severe cases and 237 deaths. The cumulative total of cases reached 12.35 million.
Meanwhile, health authorities said they had made an additional purchase of 200,000 courses of Pfizer's Paxlovid COVID-19 treatment, bringing the total number of courses of the drug available to 962,000.
