Though the COVID-19 outbreak has shown signs of plateauing recently, Hong Kong epidemiologist Gabriel Leung issues a stark warning. He urges high-risk countries to adopt China-style interventions to shield up to 60% of the world's population from the virus.
As of the latest reports, there were 44,794 confirmed cases and 1,112 deaths. The World Health Organization (WHO) remains cautious, but data indicates stagnation: in China's Hubei province (home to Wuhan), new cases dropped from 890 on February 3 to 381 on February 11—a 57% decline. It's unclear if this marks a peak or a temporary lull.
In a February 11, 2020, The Guardian article, Gabriel Leung, a renowned Hong Kong epidemiologist specializing in what was then called the novel coronavirus (now COVID-19), described the situation as "the tip of the iceberg."
Most cases outside China trace back to travelers from Wuhan. Global researchers estimate each infected person can transmit the virus to about 2.5 others. Leung projects an "attack rate of 60-80%." Even at COVID-19's 2.4% fatality rate—far lower than SARS's 13.2%—such spread would yield catastrophic death tolls.
China's unproven but aggressive measures, including confining over 55 million people, may hold the line. Leung advises other nations to follow suit to curb spread and avert "independent, self-sustaining outbreaks in major cities worldwide," a risk he flagged last month.
Containment raises tough questions: How long can cities lockdown schools, shops, and transport? And upon reopening, could the virus rebound?
