Designing infectious disease resilience into school buildings through improvements to #ventilation and air cleaning
La partie sur les méthodes qu’il ne faut pas utiliser, parce que d’efficacité non prouvée et parce qu’elles génèrent de la #pollution ;
Other strategies that have recently been implemented or considered in many schools (such as bipolar ionization, plasma systems, portable air cleaning units with ionizers or UV, dry hydrogen peroxide, photocatalytic oxidation) are generally considered less scientifically defensible due to their often unproven efficacies and due to their potential for degrading the quality of the air through the generation of harmful secondary pollutants.
Untargeted and excessive deep surface cleaning efforts (e.g., using foggers or electrostatic sprayers) should not be employed for the same reasons. Instead, schools should focus their resources on reducing the risk of #SARS-CoV-2 airborne transmission.”
