Observing the government’s compulsory home isolation order is not just a civic and legal duty, it is a key defence against the latest wave of Covid-19 infections amid a worsening global pandemic. But with no fewer than 10 quarantine breakers found in two days since the city extended health control measures for residents returning from overseas, the authorities must get tougher. The outrage caused by a viral video showing a girl with a quarantine wristband eating out at a restaurant on Monday underlines the severity of the matter. Hers was not the only case involving those wearing such wristbands. A woman was also seen at a supermarket in Whampoa, and a man with a fever was caught eating out with friends in Tsuen Wan. Those forced to self-isolate may think going out for a meal is not a big deal but, as the health crisis deepens, few can say for sure they are virus-free. To err on the side of caution is both wise and responsible. The naming and shaming on social media of quarantine breakers has been seen by some as vigilantism, but the response sends a strong message that there is no room for such irresponsible behaviour in society.

Questions have been raised whether the maximum penalty of a HK$25,000 fine and six months in jail is a strong enough deterrent. Given the potential threat to public health, there is perhaps room for adjustment. More importantly, strict enforcement is the key and earlier the authorities said they were prosecuting some cases. Only until zero tolerance is clearly shown will those quarantined realise the high cost of not following the rules. The enhanced monitoring measures announced yesterday are a positive step forward.

The message “we stay at work for you, please stay home for us” is simple but powerful. It should prompt everyone, quarantined or not, to think twice before indulging in unnecessary social activities. Concerted efforts are needed to keep infections to a minimum. Purchase the China AI Report 2020 brought to you by SCMP Research and enjoy a 20% discount (original price US$400).
