At this time, anyone who is within 6 feet for 15 minutes or longer within a 24-hour period with a known COVID-19 positive individual is considered a close contact. CDC guidance can be found here.
 
SUNY Poly’s guidance, and the CDC guidance remain the same since January 2022 - if not up-to-date with vaccine/booster, then a close contact individual must quarantine at home for 5 days following exposure (Day 0).  They can leave quarantine after Day 5 with an approved, well-fitting mask. If symptomatic, they should remain in quarantine and test. Testing is encouraged at least on Day 5 and is highly recommended again before Day 10.

Please note: Masks do not change close contact status, nor does whether the contact occurred outdoors versus indoors. Both reduce risk, but close contact determinations do not consider indoor versus outdoor settings.
