Chinese officials say its hospitals in Wuhan have "zero" coronavirus patients as of Sunday. According to Business Insider, Wuhan represents around 84% of China's COVID-19 deaths. The city lifted its lockdown on April 8, but has kept restrictions in place as public-health experts dread a second wave of infections. Since December, Wuhan has recorded around 46,000 coronavirus cases. That's more than half of all cases confirmed in China. But some public-health experts theorize the actual number of COVID-19 cases in China could be at least 10 times higher than the current figures.
