researcher suggesting up to 75% risk of #Covid19 transmission is through ‘aerosols’ (small particles) both in close proximity ~and throughout the room~, so #ventilation is critically important https://twitter.com/jljcolorado/status/1291422303272620032?s=21 https://twitter.com/jljcolorado/status/1291422303272620032
Mitigating risks in #schools - open windows & have ventilation breaks to purge air from rooms (this has implications for heating, energy use & costs) https://twitter.com/orla_hegarty/status/1289125320940032001?s=21 https://twitter.com/orla_hegarty/status/1289125320940032001

I asked @NjbBari3 about plan for 1m desk spacing (2m for teacher) & no mask requirements in Irish schools https://twitter.com/njbbari3/status/1291073473796665345?s=21 https://twitter.com/njbbari3/status/1291073473796665345
Many mechanical ventilation & air conditioning systems are set to recirculate air for energy savings (because fresh air has to be heated), systems can be re-set for higher % of fresh air to ensure virus isn’t spread around buildings https://twitter.com/devisridhar/status/1291109502352326656?s=21 https://twitter.com/devisridhar/status/1291109502352326656
