I have first hand affiliation with the DOE, public schools, and both sides of the equation (parents and teachers). I can assure you proper measure and appropriate social distancing has 100% already been taking place. You can hate on DeBlasio and I don't disagree, but NYC schools have been one of the safest places to be. Schools in other countries are also showing they are not a high rate of transmission. Various studies and date is why the CDC and WHO and other countries also now recommending that schools (especially pk-elementary) be open. If you have kids and are uncomfortable. don't send your kids to school, no one should do what they are uncomfortable with. But the overwhelming evidence is that the major point of transmission is in social gatherings and in homes and that schools have a very low rate if transmission.
