I work at an office in nyc and we have similar protocols. We can argue whether these rules are necessary or too stringent, but it appears that vt has been successful in keeping the virus under control. I think ny state has done well too since the initial wave in the spring. The recent uptick in communities that abandoned precautions like mask wearing and social distancing, I believe, is further evidence that these rules matter.
my daughter is a student at a college which has been highly successful in controlling the virus despite in person classes and dormitory living. The school does surveillance testing. Every student faculty member and employee is tested twice a week. They’re doing some 6k tests everyday and the positivity rate is .01%. I think the testing, or more particularly, the knowledge that they will be tested every 3 days, has imbued the students with a healthy respect for the mandated precautions. They aren’t engaging in risky behavior because they know 2 days later they’re going to get tested. And if they fail the test, it’s a 2 week quarantine at best, and if they broke the rules, the possibility of getting kicked out of school and losing their tuition.
