Are mask mandates making a comeback?

Concern about a "quad-demic" is growing in much of the country as the nation's hospitals see a surge in respiratory viruses.

In Southern California, most hospitals never ended their mask mandates after the COVID-19 pandemic. But now, more mandates are returning.

Medical experts predicted the surge in cases due to the holiday season, with millions of Americans mixing and mingling at airports and family gatherings.

Now, further spread is expected as millions head back to work and school.
