Singapore confirmed 305 new coronavirus cases as of 12 p.m. local time today, the country’s Ministry of Health said.

The vast majority of new infections are work permit holders living in foreign workers dorms. Two cases are Singaporeans or permanent residents.

On Sunday, Singapore reported 682 cases. The Ministry of Health said the lower number of cases today is due to “fewer tests being processed as one testing laboratory is reviewing its processes following an earlier apparatus calibration issue.”
Singapore has a total of 28,343 reported cases and 22 deaths, according to the Johns Hopkins University tally.

Making up a significant portion of the Singaporean workforce, 1.4 million migrant workers live in the city-state, mostly employed in construction, manual labor and housekeeping. Of these, about 200,000 live in 43 dormitories, according to Minister of Manpower Josephine Teo.
