If you’ve had COVID, you will know it can be pretty serious. Many of us, especially teaching and meeting in poorly ventilated and crowded rooms, especially with most folk not wearing masks, believe that we should bring back some previous restrictions.
If you find this difficult to accept, please look through this highly reputable research study carried out in schools in Boston, Massachusetts, which shows that if restrictions are removed, then COVID returns to higher levels. This is research I’ll recommend to students, since it uses a “Difference in Difference” approach for making comparisons.
