SINGAPORE (Reuters) – Singapore’s health ministry on Monday confirmed 486 new coronavirus cases, taking its tally of infections to 23,787.

The health ministry said the number of cases, the lowest in a week, were partly distorted by fewer tests being processed as one of its laboratories was recalibrating apparatus after 33 false positives were identified.

Singapore also reported one more death, bringing the virus-related death toll in the island nation to 21.

The ministry removed 35 cases from the count of infections after they were verified to be negative for COVID-19, it added.

Among the new cases, two are Singaporeans or permanent residents, while 481 are foreign workers living in dormitories in the city-state.
