Hong Kong to Mass Test Whole City for Covid With Beijing’s Help


Hong Kong is planning a testing blitz of the entire city, deploying a tactic used to root out Covid-19 cases on the mainland as the financial hub struggles to get control over its most challenging outbreak of the pandemic. 

Chinese medical experts will likely be brought in to assist in the effort, according to people familiar with the administration’s thinking, and government vans currently used for vaccinations will be converted to mete out tests, one of the people said. Officials are still deciding whether to make the mass testing compulsory, the people said, with Sing Tao Daily reporting those who refuse may be subject to a HK$10,000 ($1,280) fine. The push will begin in early March and be conducted over weeks, other local media said. 

A representative from the Hong Kong government didn’t immediately respond to a request for comment. Local stocks tied to economic reopening advanced in Thursday’s session as market watchers said the mass testing move could help stem the resurgence of cases.

President Xi Jinping has called for the city of about 7.5 million people to take “all necessary measures” to contain Covid, as the widening outbreak — which came after months of being virus-free — undermines China’s zero-tolerance approach to keeping the pathogen out. While other parts of the world start to live alongside Covid, Beijing is continuing to pursue elimination, including testing as a key tool in an arsenal that also includes effectively closed borders and lengthy mandatory quarantines. 

Some experts worry Hong Kong’s move will come too late. 

Outbreaks on the mainland have been successfully contained through frequent and mass testing, but China has never used the strategy in an outbreak of this size. It’s also unclear where Hong Kong, which is currently struggling to find more isolation and quarantine units, would house those who test positive, even as the city insists on its pursuit of the Covid Zero approach.

“At current rate of spread, there could be tens of thousands of new cases each day in early March, and we know that not every infection is being confirmed so the number of infections picked up in mass testing could be very large at that point,” said Benjamin Cowling, a professor and chair of epidemiology at the University of Hong Kong. “Doing mass testing in April or May, when the fifth wave will have subsided and we would then have capacity to isolate the positives, might be able help the city return to zero daily cases if that were the objective.”

First Time

It would be the first time since the pandemic began that Hong Kong has enforced citywide testing, with the more contagious omicron variant providing the steepest challenge yet to maintaining the Covid Zero approach. Hong Kong’s infections tally continues to set records, with local media saying about 5,000 new cases will be reported Thursday. New infections reached 4,285 on Wednesday and there were 16 patients in a critical condition, all adults. Officials announced 10 deaths, including a three-year-old girl.

The requirement to isolate all positive cases is already straining the city’s medical system. Hong Kong Chief Executive Carrie Lam has asked major property developers to make thousands of hotel rooms available to house positive cases, according to a person familiar with the discussions. Omicron has exposed Hong Kong’s lack of preparation for a major outbreak, with policy shifting on an almost daily basis to try and maintain a strategy that other places have left behind in favor of treating Covid as endemic.

The chaos of the current outbreak — with hospitals overwhelmed and elderly patients housed in makeshift tents outside — has undermined already-damaged public confidence in the Hong Kong government’s abilities following unprecedented unrest in 2019, says Joseph Cheng, a retired political science professor and veteran democracy activist. Many may be dissuaded to participate in the testing drive by the long queues already being seen at testing sites, he said. 

“There’s a lot of worry about the lack of competence, the lack of preparation of this government — there’s a lack of hospital beds, and people are having to wait up for days to be contacted if they’re positive,” said Cheng, who left the city for Australia when China imposed a national security law on Hong Kong in 2020, adding that “the majority of the people are willing to cooperate.” 

“They are pragmatic, they are practical,” he continued. “If tests are made compulsory, they’ll be willing to accept that. They just want to be able to go back to work. Hong Kong people will grumble a lot, but most people will still go and queue up.”
