Quote: Our data on almost 200,000 kids in 47 states from the last two weeks of September revealed an infection rate of 0.13 percent among students and 0.24 percent among staff. That’s about 1.3 infections over two weeks in a school of 1,000 kids, or 2.2 infections over two weeks in a group of 1,000 staff.
BC, I suspect you must not have thought about those numbers.
They quote numbers like 0.13% and 0.24% yet those numbers aren't at the Qualtrics site. The closest (but higher) numbers are for confirmed cases only.
The numbers in the data currently are (confirmed+suspected) 0.73% and 0.77%, 2-week periods). COVID is infectious whether or not it is confirmed.
The Texas total numbers are muddied as the start dates vary per district. Texas is only reporting test-confirmed cases.
California defines its highest level of precautions (where schools may NOT open) as "widespread" (purple) with more than 7 daily new cases per 100K.
(confirmed, students) 0.151% for a 2-week period = 10.8 daily cases per 100K
(confirmed+suspected, students) 0.73% for a 2-week period = 52.1 daily cases per 100k.
(confirmed, staff) 0.28% for a 2-week period = 20 daily cases per 100K
(confirmed+suspected, staff) 0.77% for a 2-week period = 55 daily cases per 100K
Texas: (confirmed, students) 0.14% for a 1-week period = 20 daily cases per 100K.
Wow, that's high.
