Is 90,000 staff and teachers a large enough pool to study for folks? Duke University published a study in Pediatrics, which the CDC has also cited.
"The study included data from 11 of the partner school districts that were open for all nine weeks of the first quarter and agreed to track both COVID-19 case count and secondary transmission for research purposes. From these districts, which included over 90,000 students and staff attending in-person instruction, there were 773 cases acquired from the community. In contrast, contact tracing from the state health department identified only 32 infections that were acquired within schools through secondary transmission." https://jamanetwork.com/journals/jama/fullarticle/2775875 https://today.duke.edu/2021/01/duke-study-when-schools-take-covid-safety-measures-viral-transmissions-person-schooling-are?utm_source=newsletter&utm_medium=email&utm_content=Duke%20study%20on%20schools&utm_campaign=Weekly_2021-01-30 |

Anecdotally, in a classroom of 30 masked kids ages 4-5, there was no spread from the kid that tested positive to the other 29 kids. This is FT preschool, where lunch and snacks are served daily. These are little kids who have to eat without masks twice a day, plus they play way together without strict social distancing. So while you'd think this is a high risk of transmission environment, I was pleasantly surprised to find out there was no transmission, even though kid who later tested positive was at school before finding out testing positive. The "no transmission" from kid to kid has happened all three times. So after going through that, I feel much less worried. |
To clarify, parents being notified a kid tested positive in their classroom occurred at different times. Totally separate cases that occurred 4 weeks or 2 months apart. In each situation, there was no infection from positive kid to anyone else at school. |
This is the best example of a solid study about COVID in schools that I have seen. Until this report, which looks like it was released this week, I haven’t seen any with a significant sample size that seems to prove what people have been screaming since March. I hope this one sticks and is supported when our children return. |

Do these studies involve cohorted kids? I worry that this won’t hold up with the new variants. And that such poor/little contact tracing is done in VA that no one will have any idea where the virus is coming from. Data on tracing is almost useless in the US. No one is doing it well because we’re off the charts on case numbers. But I hope the study holds for the sake of the high school kids going back!!! |
