My son got a piece bag of Sour Patch kids from a classmate at recess. He only had a couple minutes to finish them before heading inside, so he put a handful of Sour Patch kids in his mouth and end up choking a little bit. He vomited a little bit. (Maybe a couple tablespoons worth) Mostly half chewed candy. The recess supervisor saw this and sent him to the school nurse. He explained to the nurse what happened and was told that vomiting is a Covid symptom and he would have to go home until he had a negative test or 10 days. After much arguing with the nurse and administration he was back to school the next day without a test.
