As the world struggles with the rapid spread of Covid-19, Hong Kong appears to be having success controlling it -- in part because the memory of a similar virus in 2003 prompted a public outcry early on.
Hong Kong’s government quickly implemented restrictive “social distancing” measures now being hotly debated around the world, in part because of pressure from medical workers to close its border with China at the beginning of the outbreak. Those included closing schools, canceling large-scale events, shutting government offices and ordering civil servants to work from home -- a move that many companies quickly followed.
Hong Kong’s experience with Severe Acute Respiratory Syndrome -- which killed almost 300 people of more than 1,700 infected, the most outside of mainland China -- impacted the psychology of the city, said Nicholas Thomas, an associate professor at the City University of Hong Kong. Many residents wore surgical masks and avoided gatherings from the very start of the outbreak, a practice that continues more than six weeks later.
“As soon as the virus started to break out, and people read ‘China’ and ‘coronavirus,’ people remembered,” said Thomas, who has edited an academic book series titled “Health Security and Governance.” “The social part is one of the reasons why we’ve been able to keep the virus cases so low, because in some way the public has been able to make the government take measures.”
In recent days, the virus’s spread in the U.S. -- highlighted by the National Basketball Association’s decision to suspend the season -- has driven home the need to avoid large gatherings, even as some government officials have maintained there’s no reason to panic. Recent high-profile infections, including actor Tom Hanks, the Australian home affairs minister and the wife of Canadian Prime Minister Justin Trudeau, also underscore the need to take early precautions.
Most of Hong Kong’s restrictions were put in place at the end of January, when the city had only a handful of cases. As of Monday, it had 139 cases in total, and only four deaths. By contrast South Korea didn’t start taking unprecedented measures until Feb. 23, when hundreds had already been infected. It has now seen more than 8,100 people infected and 75 deaths.
New York City also acted much later by comparison. On Sunday evening, Mayor Bill de Blasio announced that public schools would be shut from March 16 as the city’s tally soared over the weekend to 329 confirmed cases and five deaths.
For Hong Kong, the relative success marks a bit of good news in what has been a devastating 12 months for the economy. The virus is further curbing growth after violent pro-democracy protests periodically shut down large parts of the city in the second half of 2019, prompting Beijing-appointed leader Carrie Lam’s popularity to plummet.
The effective virus response hasn’t helped Lam much. She initially resisted public pressure to fully shut the border with China, relenting only as thousands of medical workers began a strike that put pressure on officials and the health system. Her approval rating rose to 13% on March 3 from just 9% on Feb. 27, according to the latest survey released by the Hong Kong Public Opinion Program.
Earlier Intervention
Deploying measures early can have a dramatic effect. Research on the 1918 influenza pandemic in the U.S. showed cities that had implemented multiple “non-pharmaceutical interventions,” including closing schools and churches, experienced death rates that were as much as 50% lower -- as well as less severe outbreaks -- than those that did not.
