I think a lot hinges on gaining trust in the testing. Maybe Hamilton administration has a lot of faith in the 2x per week testing, and the faculty does also. Sounds like a VERY successful semester so far!
It is becoming clear to me that 2x a week is really working, even in city schools that are more porous to their surroundings. I think I read some top epidemiologists (not sure where, sorry) say that testing every two days with 1 day turnaround for results is sufficient to prevent spread. So, say the campus weeded out all positive cases in the first week or two during the initial quarantine phase, so you have all undergrads without covid. Then even if a kid, Joe, goes out to a gathering in the city with non-classmates and catches covid, Joe will test positive using these sensitive pCR tests before he is infectious. So Joe will be whisked off to isolation jail before he can give covid to his roommate Juan or anyone else on campus. So frequent testing doesn’t prevent you from catching covid, but prevents you from spreading it on your campus. It’s a giant luxury on these campuses for kids to know that literally everyone they are spending time with has tested negative in the past 2-3 days. I recall reading that testing 3x a week would totally work, but I imagine 2x a week is also enough to halt spread. It certainly looks like it is working in practice, seeing the results on a variety of campuses. And on more rural campuses, there are very, very few opportunities for covid to leak in anyway.
Looking at large city schools like BU and Northeastern, where it would be almost impossible to create a bubble like Hamilton can, they have had a sprinkling of positive cases, but nothing we would consider an outbreak. It looks like their 2x a week mandatory testing completely works to prevent spread.
My child’s school isn’t organizing a lot (any?) of social activities for the students, but they are providing 3x a week testing and allowing students to spend time throughout Boston, Cambridge, etc. They are not communicating a lot about their strategy, but I kind of feel like they are whispering, “ok you dummies—we can’t say this explicitly, but you are really safe—go enjoy what the area offers, following state rules. Appreciate this giant gift of testing we are giving you that enables you to know your classmates are exceptionally unlikely to have covid”. One nice side effect is that my freshman has actually taken much more advantage of Boston than their older sibling did at this point freshman year, when there were more on-campus activities.
However, I’m not hopeful that this particular school will resume in person classes until next fall, even if they get to December with no or very few student cases. Luckily the remote classes are going well for my child so far, but we’ll be glad for in-person to resume.
Sure wish the rest of us throughout the country could have such frequent testing! But good for these schools for figuring it out. And hopefully schools that aren’t doing mandatory frequent testing are figuring out how to do it for 2nd semester. Hoping the cheaper tests will help them.
