A recent study from the University of Bristol suggests that Covid particles become 90% less infectious within as little as five minutes. I don’t know whether the UK will get much benefit from measuring PM2.5. The CO2 monitors will alert them to open windows and that’s about all that can be done. https://www.medrxiv.org/content/10.1101/2022.01.08.22268944v... |
