Current COVID-19 Cases in Cascade County


As of Wednesday, 3/17/21, Cascade County has achieved a case rate of less than or equal to 10 new cases per day per 100,000 population, for two consecutive weeks. As a result, the mask mandate and event capacity restrictions have been lifted, effective immediately.

As of April 14, 2021, we are posting a weekly COVID-19 update report rather than a separate daily update. Alternately, you can find the weekly updates on our Facebook page.

The current weekly average case rate is always listed on the most recent COVID-19 Weekly Update. See below (Understanding Case Rate) for an explanation of how the case rate is calculated.

If you would like to check daily numbers for cases and vaccinations, they are available here. That site is updated daily (except weekends), and you can use the tabs at the top to switch between case and vaccination numbers.

If you would like to check the most recent positivity rates (tracking the percentage of tests that were positive), they are available here. Those reports come out each week and cover the preceeding two weeks of testing - however there is a lag of about seven days (e.g., the report dated 6/1 was released on 6/8 and covers 5/18 through 6/1). Please note that the reference to Nursing Homes is because the positivity rates affect the ongoing testing procedures for nursing homes.

Important notes

  1. If you have been instructed to isolate or quarantine and need a letter for your employer, DO NOT COME TO CCHD IN PERSON. The last thing we need is our public health staff, already stretched thin, to be exposed. Instead, call us at 406-454-6950 or email us at [email protected] and someone will respond ASAP.
  2. The City-County Health Department does NOT perform COVID testing. If you have symptoms or have learned that you may be a close contact, please call a healthcare provider to get more information about being tested. Your provider will let you know when your test results have come in and will give you your initial instructions—to quarantine, isolate, or neither—and we at CCHD will get in touch with you as soon as possible.

What can you, our community members, do to slow the spread?

  1. If you are positive for COVID-19, isolate at home. Notify everyone you were in contact with for 48 hours prior to the onset of symptoms or 48 hours prior to test date.
  2. If you have been told that you are a contact, quarantine at home for ten days from the time you were last exposed.
