The Ministry of Health (MOH)  preliminarily confirmed 1,426 new Covid-19 cases earlier on Monday afternoon, April 20.

This is the highest single-day increase in the number of reported cases thus far, and brings the total number of confirmed Covid-19 infections in Singapore to 8,014.

Of the new cases, 25 were found in the local community. 18 are Singapore citizens or Permanent Residents, while seven are Work Pass Holders.

1,369 cases are Work Permit holders who reside in dormitories.

This is by far the largest spike in cases related to foreign worker dormitories in Singapore.
