I think you are confusing (i) closing schools in March (about which this article is and which I argued was a necessary thing to do as reasoned above) vs (ii) keeping schools closed NOW and not reopening (which is not the discussion here). The FHI report is about letting the schools open now as is being done in neighbouring countries but not yet done in Norway (correct me if it argues that schools should never have been closed). I could imagine that might be the right thing to do seeing that its happening EU-wide.
