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.
