In Missoula, the health department says there is some confusion over what rules to follow after the governor's statewide announcement.
Missoula County mandated masks in indoor public places last week, but there are some discrepancies between the local order and the state directive.
Missoula County said anyone over the age of 12 had to wear a mask, but the governor says it's anyone over the age of five. The governor also said face shields are okay, but Missoula says they aren't enough. So what do you do?
The health department clarifies that local governments have to abide by the state orders, but can add more restrictive rules if they want.
Incident Commander Cindy Farr says, if you're still confused, follow the rule that is most strict.
"Whatever is the most restrictive between the two, is the one you need to follow. It's really important that you remember that, because other jurisdictions, like Whitefish have also passed local orders. If you're traveling, you want to make sure that you familiarize yourself with whatever the local order is in that area," said Farr.
That means anyone over 5 must be wearing a face covering.
But if you're in Missoula County, that has to be some kind of cloth mask, and not a face shield.
Farr says the Missoula City-County Health Department is putting together a "frequently-asked questions" page on their website to address some of these issues.
