I suspect the ban on countries will happen AFTER all the HK kids overseas arrive back in Hong Kong.
If the Omicron virus is so contagious that arrivals from hardhit countries have to spend 7 days in Penny Bay, then why would you transfer them on day 8 to hotels afterwards? Why day 7 ? why not day 8, 9, 10?
Is it day 7 is considered safe because pass the incubation period??
