The rampaging coronavirus is revealing new unpredictability as the promised post-holiday surge continues, with some hospitals now seeing a rise in patients sick with COVID-19 who had no underlying medical conditions, officials say.

Earlier in the pandemic, only 7% of COVID-19 deaths in Los Angeles County occurred among people with no underlying medical conditions, while now, 14% of deaths are among that group, the Los Angeles Times reports.

The Bay Area overall passed yet another depressing milestone Sunday, with more than 3,000 COVID-19 deaths since the start of the pandemic.

Globally, more than 90 million people have been infected and nearly 2 million people have died, including more than 374,000 Americans, data tracked by Johns Hopkins University shows.
