INDIANAPOLIS — Sixty-five of Indiana’s 92 counties should mask up indoors regardless of their vaccination status, according to new federal guidelines.

The Centers for Disease Control and Prevention said Tuesday that counties with “high” or “substantial” amount of COVID-19 spread should wear masks inside, even if they’re fully vaccinated.

A look at the CDC’s map shows about two-thirds of counties nationwide are in those categories, including 65 Indiana counties.

The CDC classified “substantial transmission” as meaning there have been 50-100 cases per 100,000 over a 7-day period. “High transmission” means an area has seen more than 100 cases per 100,000 over a 7-day period.
