Coronavirus death toll reaches 1484

The number of novel coronavirus cases has risen to more than 64,000 worldwide, after China reported another major increase at the epicenter of the outbreak following a change in how authorities there diagnose cases.

As of Friday morning, over 100 more people had died of the virus, officially known as Covid-19, in central China's Hubei province -- raising the global death toll to 1,484. Of those, all but three have died in mainland China.

Chinese health authorities also confirmed an additional 5,090 cases across the country. That's a major spike, but nowhere near the 14,840 new cases reported Thursday -- the largest single-day rise since the epidemic began.
