Prime Minister Lee Hsien Loong also on Tuesday, April 21, announced the extension of the circuit breaker measures till June 1.
“... Unfortunately that number of unlinked cases has not come down, and this suggests there is a larger, hidden reservoir of cases in the community; and this reservoir is the source of these unlinked cases, which we have not detected,” said PM Lee in an address to the nation.
The MOH on Monday had said that extensive testing at foreign worker dormitories had resulted in a higher number of cases.
"These are not new infections as the workers are staying in their rooms and many have not reported sick. But when the teams go in to test them, many turn out to be positive."
However, most of those infected have mild symptoms and are being monitored in community isolation facilities or general wards. None are in the intensive care unit, MOH had said.
