Los Angeles County is reinstating an indoor mask mandate regardless of vaccination status as the highly transmissible delta variant of COVID-19 continues to spread. Michigan family physician Dr. Farhan Bhatti joined Cheddar to break down the decision to reimpose face masks. "If numbers continue to rise in other parts of the country, particularly, pockets where there's large groups of people that are unvaccinated, then we're going to see other people following suit," said Bhatti.
