Isolation, Quarantine, and Masking Guidelines

(Last updated 8/30/2022 at 9:30am)

COVID-19 Isolation & Quarantine:


Isolation is used to separate people with confirmed or suspected COVID-19 from those without COVID-19. VIEW THE UPDATED CDC GUIDANCE ON COVID-19 ISOLATION HERE.

Quarantine is used to prevent transmission of COVID-19 by keeping people who have been in close contact with someone with COVID-19 apart from others. VIEW THE UPDATED CDC GUIDANCE ON COVID-19 QUARANTINE HERE.

Please contact CCHD with questions at 406-454-6950 or [email protected]

Masking recommendations:


The CDC is currently recommending masking based upon the "COVID-19 Community Level" of your area. The Community Level is determined by the number of new COVID-19 hospital admissions per 100,000 population and the percent of staffed inpatient hospital beds occupied by COVID-19 patients - click here for details.

The current Community Level, and the applicable masking recommendations, can be viewed HERE.
