A travel bubble between Hong Kong and Singapore set to open on May 26 has a high chance of being postponed, as stated by Hong Kong officials today. Earlier it was slated to begin in November but was suspended after a spike in cases in Hong Kong. This time it is Singapore that is seeing an increase in cases.<br />'' <br />''The arrangement would allow passengers to travel between the two cities without having to spend time in quarantine, provided they test negative for the virus before departure and upon arrival. But under the agreement, the bubble would be suspended if the seven-day moving average of the daily number of COVID-19 cases in the community is more than five for either Singapore or Hong Kong.<br />'' <br />''<span style="color: #222222;">Singapore's health ministry yesterday reported 24 locally transmitted COVID-19 cases, the highest daily number since mid-September, with 17 of them linked to a cluster at its Changi Airport. Earlier on Friday, Hong Kong Health Secretary Sophia Chan said people arriving in the city from Taiwan would be required to quarantine at a designated hotel for 14 days upon arrival after a rise in domestic cases there.</span><br />
