20 Quarantined At 2 Schools

What does cases "in" or "at" the school mean? A student at the school test positive and it's been determined they caught it AT school? Or, a students test positive, no one knows where they got it, and those in contact are quarantining? That's an important distinction when discussing whether schools are safe or not.

Yes, thank you this distinction is KEY as we continue to report out these numbers. A positive case shouldn't automatically be equated with in-school transmission.

The rate of infection in CT schools/communities across all three modes of learning (remote, hybrid and in person) shows that in person is no less safe than the other two modes. The harm caused by not being in school is far greater. The Health Director and our Mayor are either incapable of the critical thinking needed to see the issue from a cost-benefit perspective, or they are intentionally keeping New Haven 6-12 graders home. In doing so, they are placing our children and the future of this city in jeopardy.
The COVID cases cited in this and the other articles re: K-5 in person learning are just that, cases. They have not resulted in increased hospitalizations, spread or deaths. Yet, our older students continue to rot academically, lose needed socialization and physical activity. But, those teachers unions sure are happy.

It means that someone that is attending the in person school session, be it teacher, student or staff has tested positive for Covid-19 or come in contact with a positive person. They claim they contact trace, but that depends on what you call contact tracing. They don't say who due to HIPPA rules, so how are they to know who talked to who? Their contact tracing is guessing at best, and they can't be sure who had contact with who unless they ask everyone. But that does not happen, they don't know who spoke to someone in halls, or in the parking lot. We forget meaningless chit chat that we have in passing. But I'm sure if they did a thorough contact tracing for those people that are positive they would see they encounter many more people than they "guessed".

DJKsMom: The CDC standard for for contact tracing, and quarantine, is "close contact" of at least 15 minutes. So, no, passing in the hallway does not count, as it is unlikely to lead to transmission. As Albert Ko said, dosage matters. Regardless. since, as NHPS Family states, in-person students have no higher rates of infection than hybrid or remote, why not do in-person? If in-person or hybrid led to more infections/disease, we would have higher rates. By abstaining from full in-person learning, which at least 50% of districts are doing, we lose the benefits of in-person learning but gain nothing in infection control.
JT: Yes, cases in or at a school mean that a person who was in or at the school has tested positive. It may be a student, faulty, staff, or the copier repairperson. We don't know where they contracted it, although it's most likely not in the controlled environment of the school, but in the uncontrolled environment of the home or other social setting.
