My daughter’s elementary school will not require masks if the outside temperature is 75°F or over. They said that means masks will effectively not be worn on classrooms for the entire month of September, and probably through October as well. In general, the COVID measures are based on outdated conjectures about how the disease is spread, and will be ineffective against an airborne pathogen. My wife wants to pull our daughter out of school. I’m not sure what the right call is, because I’m not sure how to quantify the risk or be sure about what would be equitable for my daughter.
