Chicagoans need to mask up indoors and get their COVID-19 booster shots as most of the larger metro area is now considered a high threat for the spread of the virus, a top health official said Thursday.
Chicago Public Health Commissioner Dr. Allison Arwady stopped short of announcing mandates for masks or proof of vaccination to enter public spaces but said on Thursday that such measures could be reinstated if cases and hospitalizations continue to climb.
