  • You are not vaccinated or have not completed a primary vaccine series.
What to do if quarantined?
  • Stay home and away from other people for at least 5 days after your last contact with a person who has COVID-19. The date of your exposure is considered day 0.
  • Wear a well-fitting mask when around others at home, if possible.

    • Shortness of breath
    • New loss of taste or smell

  • Isolate for at least 5 days. If you have symptoms, to calculate your 5-day isolation, day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed.
  • You can leave isolation after 5 full days if you are asymptomatic or if you have mild symptoms, you must be fever-free for at least 24 hours without fever-reducing medicine, not have a runny nose and have no more than a minimal, non-productive cough.
  • You must continue to wear a well-fitting mask around others at home and in public for an additional 5 days (day 6 through day 10) after the end of your 5-day isolation period. If you are unable to wear a mask around others, you must continue to isolate for a full 10 days.
  • If you continue to have a fever or your other symptoms have not improved after 5 days of isolation, you must wait to end your isolation until you are fever-free for 24 hours without the use of fever-reducing medicine and your other symptoms have improved.
