For contact tracing purposes, a "close contact" is anyone who spent 15 minutes or more within a 24-hour period and was within 6 feet of a person infected with COVID-19 while they were infectious (2 days before onset of symptoms to 10 days after).

Note: If you have NOT received all recommended COVID-19 vaccine doses (unvaccinated, haven't completed a primary vaccine series, or are 18 or older and more than 5 months out from your second Pfizer or Moderna dose, or more than 2 months out from your J&J vaccine dose but haven't received a booster dose): you should stay home and quarantine for 5 days, monitor for symptoms, and get tested at least 5 days after exposure.
