      Two uses of "science" in everyday parlance. There is (1) a method of investigation of natural phenomena, and (2) a religion. Typically "science shows" something, it's second type. More socially acceptable in bougie circles to claim science than to say "I have a superstition".https://twitter.com/MartinKulldorff/status/1289104607428345857 …

      Wonderful that we have one governor in this country that follows the science rather than the media: "Science shows not going to school hurts kids more than COVID". https://twitter.com/govkristinoem/status/1288920548261552129 …

      Here is my usage: -Sweden never closed day-care/primary schools, with zero COVID19 deaths among 1.8 million children ages 1-15. So, less risk than annual flu. -Children greatly benefit from school. I am sure that you, an epidemiologist, agree with both. https://folkhalsomyndigheten.se/contentassets/c1b78bffbfde4a7899eb0d8ffdb57b09/covid-19-school-aged-children.pdf …

      Kids don't die of COVID-19 (by and large). Kids die from influenza (regularly, esp 0–5). So it's not a v. interesting comparison. The reason to close schools has nothing to do w/kids, TBH. Whether or not to close schools is debatable, but it's good to have the right context.

      Teacher safety is another argument used against #OpenSchools. We can use same counterfactual/ref. With schools open, compared to other professions, the COVID19 RR was 0.9 (95% CI 0.7-1.1) for day-care and 1.1 (95% CI 0.9-1.3) for primary school teachers. Sample size 260K. 1/4

      @MartinKulldorff Was the reference group for the RR estimate really all other professions? Not familiar with the Sweden context, but if uncontrolled transmission is occurring in other professions, infection risk among teachers may be very high... similar to other professions.

      Comparison was all others professions except health/elder care workers. With occupational testing, they would have biased the results if included. Jobs with highest risk were e.g. cab/bus drivers, janitors and restaurant workers.https://www.folkhalsomyndigheten.se/publicerat-material/publikationsarkiv/f/forekomst-av-covid-19-i-olika-yrkesgrupper/ …

          I think kids should go back to school because that's what I think. Science these days seems to show a lot of people exactly what they want to see.
