Community transmission is defined as illness within a community that lacks connection to travel or other confirmed cases.

CDH and SWDH are closely monitoring COVID-19 cases in their jurisdictions and anticipate continued spread of this illness throughout Idaho and our counties. Both local health districts urge their communities to follow outlined strategies to help slow the spread of COVID-19 and avoid overwhelming our health care system while protecting our most vulnerable populations.

What should people do to help reduce community transmission?

Public health recommends the following:

  • Practice social distancing: avoid crowds, maintain at least 6 feet from others when possible
  • Decrease time in group settings when possible
  • Limit unnecessary travel
  • Consider postponing or canceling out of town vacations and travel out of state
  • Use drive through and delivery services for everyday errands where possible
  • Persons at increased risk of severe illness should consider sheltering in place
    • Only leave your home for “essential activities,” to work for an “essential business,” or for “essential travel.” Do not host or attend any gatherings
  • Persons with recent travel to an area having widespread community transmission or a shelter in place order should shelter in place at home until 14 days after return.
  • Create a plan for how to safely care for a household member if they become ill

While today’s community risk is still relatively low, this is rapidly changing. We ask that the public keep informed on developments and information from their health departments, which can be found at: and

If you are experiencing signs and symptoms associated with respiratory illness and do not need medical care, you should follow steps for self-isolation. If signs and symptoms worsen, please seek health care.
