Hong Kong's daily COVID-19 cases reached a new high of 614 on Monday. The University of Hong Kong's Ben Cowling discusses whether this fifth wave of infections will be a turning point for the zero-COVID strategy or lead to stricter pandemic restrictions. The vaccination rate in Hong Kong lags behind that of Singapore and Taiwan, with only about a fifth of those over 80 being protected. The city faces a choice between tightening mainland-style measures or reassessing its priorities and weighing the risks of gradually opening up against continued restrictions.
