      Italy closes schools nationwide. https://www.bbc.com/news/world-europe-51743697 … If one thinks one will close schools when cases strike, it’s better to close earlier than later. That is, close them when cases occur in nearby areas. By time there are index cases in schools themselves, it’s late. 11/

      Model of #schoolclosure for H1N1, striking population w school system & demography of Italy, indicates reactive *phased* policy of closing classes, then grades, then schools, might be nearly as effective as closing schools. I'm skeptical https://bmcinfectdis.biomedcentral.com/track/pdf/10.1186/s12879-016-1918-z … | @alainbarrat 12/

      Analysis of school closures in Japan during pandemic H1N1 flu in 2009 showed an impact: cumulative number of infected *students* decreased by 8% and maximum peak by 24% (flattening epidemic with NPI -- non-pharmaceutical interventions). #schoolclosures https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144839 … 13/pic.twitter.com/svEi5hswgf

      School closures slow epidemics even if kids are not susceptible. But closures really help if kids can get sick. New analyses from China reveal that children can indeed get #COVID19 (though most studies show at very low rates). https://www.medrxiv.org/content/10.1101/2020.03.03.20028423v1 … via @cmyeaton 14/

      Nicholas A. Christakis Retweeted Bloomberg

      Example of reactive school closure when proactive would be better. If you plan to close the school when there is a case, and if there are already community-acquired cases in the epidemiologically relevant region around you, proactive closure is better https://twitter.com/business/status/1237140620134756358?s=21 … 16/https://twitter.com/business/status/1237140620134756358 …

      Using syndromic surveillance, @mandl et al showed that, for influenza, it’s kids first (red), then adults (blue), then deaths from influenza—mostly in the elderly (black). This is one reason closing schools helps. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4128871/ … #schoolclosure 19/pic.twitter.com/rN60k6c0pm

      Replying to @NAChristakis @mandl

      I think it makes sense but we still don’t know kid infectiousness for this, unlike flu, plus effects of possible shift to grandparent care. This one is tough.

          We know kids can carry high viral loads. And school closure works even when kids are not vectors, by keeping adults at home.

          Right, and i think that’s the preponderance of evidence but I think there’s a lot of uncertainty here unlike flu.
