COVID-19 Isolation and Quarantine Guidance

Kenosha County Public Health - COVID-19 Isolation and Quarantine GuidanceThis isolation and quarantine guide was compiled in response to the latest Centers for Disease Control & Prevention guidance, last updated in January 2022. Kenosha County Public Health encourages individuals and businesses to use and follow this simplified guidance to promote health and safety.

If you have tested positive with COVID-19 and are symptomatic:

  • Stay home for at least 5 days from symptom onset
  • If you have no symptoms or your symptoms are resolving* after 5 days, you can leave your home and return back to normal activities.
  • Continue to wear a well-fitting mask around others for 5 additional days (day 6—10).

If you have a fever, continue to stay home until you are fever free for 24 hrs (without any fever-reducing medication.)

*Resolving can be roughly equated to feeling “on the mend.” Case symptoms should be lessening, not simply staying the same or worsening.

If you have tested positive and are asymptomatic:

  • Stay home for at least 5 days from test date
  • If you have no symptoms, you can leave your home after day 5 and return back to normal activities.
  • Continue to wear a well-fitting mask around others for 5 additional days (day 6—10).

If you are a close contact/household contact of someone who has tested positive


And you have been fully vaccinated within the past 6 months with Moderna or Pfizer, or with Johnson & Johnson within the past 2 months; or if you have received a booster dose, or had a lab-based positive confirmatory or antigen test within 90 days of the exposure:

  • Wear a mask around others for 10 days from last exposure
  • Test on day 5 after exposure, if possible.
  • If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19.

And you are NOT vaccinated, partially vaccinated, or vaccinated more than 6 months ago with Moderna or Pfizer, or with Johnson & Johnson more than 2 months ago, and not boosted, or had a lab-based positive confirmatory or antigen test more than 90 days from the exposure:

  • Quarantine for 5 days from last exposure with positive case
  • Monitor for symptoms for 10 days
  • Test on day 5 after exposure, if possible.
  • Continue to wear a well-fitting mask around others for 5 additional days.
  • If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19.
