Having good safety measures at schools is very important as children start going back to the classroom. But which measures are most effective at optimising health and safety conditions and preventing the spread of COVID-19 in school settings?
In a new study, researchers from various institutes including the Institute of Global Health (IGH) at the University of Geneva (UNIGE) and CERN used the CARA tool to model the concentration profiles of potential airborne viruses in a classroom of 160 m3 containing one infectious individual. A comprehensive analysis was conducted in order to find optimal solutions in different scenarios. It found, for instance, that natural ventilation - while a necessary measure - is more effective in winter than in summer.
