Quarantine When Masks are Worn


January 4, 2021


In K-12 instruction areas where there is close contact* between a person who has tested positive for, or is diagnosed with, COVID-19 (case) and students or staff (contact) and both the case and the contact were wearing masks** during the time physical distancing could not be maintained: 

  • The case must isolate at home as recommended by public health officials¥.
  • The contact may attend in-person classes, but must monitor themselves closely for COVID-19 symptoms during the two weeks after exposure. If they develop symptoms, they should stay home and contact a healthcare provider.

Students or staff who are close contacts due to an exposure outside of instruction areas are still required to self-quarantine§.



*Close contact is defined as being within 6 feet for 15 minutes or more.

** This policy is only applicable to those wearing a mask that covers both the nose and mouth.


  • ”Self-quarantine” should be considered synonymous with “self-isolation” in Idaho.
