If you have tested positive or have been exposed to someone with COVID-19: 
Follow the isolation/quarantine guidelines below or use the CDC calculator. 
Please contact Walworth County Public Health if you have any questions.

Update as of 12/13/2021: Due to an increase in COVID-19 cases, you may not receive a disease investigation or contact tracing call from the Walworth County Division of Public Health. Please review the following guidance:

If you have tested positive for COVID-19 (regardless of vaccination status): 

  • Isolate away from others for at least 5 days since your symptoms first appeared or the date you tested positive if you have no symptoms. 
  • On day 5: if you have no symptoms or symptoms are resolving, you may end isolation but continue to mask around others for an additional 5 days.
  • If you have a fever, continue to isolate until your fever resolves.
  • Notify your close contacts. A close contact is anyone with whom you have had physical contact or who has been within 6 feet of you for 15 minutes or more (either continuously or over any 24-hour period). Talk to anyone who was a close contact two days before you started to have symptoms through the end of your isolation. If you did not experience symptoms at the time of the test, talk to anyone you had close contact with two days prior to taking the test through the end of your isolation. Let them know that you tested positive for COVID-19 and instruct them to follow the current recommended quarantine guidelines.
  • Notify your employer, school, or other organizations you were at so they can complete contact tracing and quarantine those that were exposed. 

If you have been told by someone who tested positive that you are a close contact.

If you are boosted or  completed Moderna/Pfizer  2 dose vaccine within 6 months or completed Johnson & Johnson vaccine within 2 months:

  • Wear a mask around others for 10 days.
  • Test on day 5, if possible.
  • If symptoms develop: test and isolate.

If you are unvaccinated or completed your Moderna/Pfizer series more than 6 months ago or completed Johnson & Johnson more than 2 months ago:

  •  Quarantine away from others for 5 days, after day 5 continue to wear a mask around others for 5 more days.
  • If you are unable to quarantine, wear a mask around others for 10 days. 
  • If symptoms develop: test and isolate.
