Coronavirus: extra 16 arrivals test preliminary positive, source says, on top of sudden daily surge of 30 confirmed imported cases
- Previous high was on April 3 when city recorded 43 new infections
- No new local cases reported, extending current streak to nine days

The possible new cases were arrivals who had tested preliminary positive after the official daily cut-off time of 4pm. This group was also believed to be mostly returnees from Pakistan.
The highest single-day count in more than two months came as local infectious disease experts found that the coronavirus was attacking two types of human cells essential to the immune system. Experts said this trend could be behind some of the most arduous fights against the disease suffered by patients.
The Centre for Health Protection said 29 of the fresh cases had been to Pakistan and returned to the city via flight EK380. Twenty six of them came back on Saturday, and three on Sunday. All have been transferred to hospitals from quarantine centres.
A 46-year-old man confirmed infected on Monday returned from the Philippines on June 9 and was undergoing home quarantine for 14 days.
Residents returning from places deemed to be high risk, including India, Pakistan and Bangladesh, are sent to the centres for 14 days.
