The city-state went into a lockdown in mid-April after mass outbreaks in cramped migrant worker dormitories pushed its caseload to one of the highest in Asia.
Last week, it said it had cleared infections from all of the dormitories - housing around 300,000 workers - barring some blocks which continue to serve as isolation zones.Of Tuesday's cases - its lowest tally since April 2 - the majority were among those remaining workers serving quarantine.
