By the way no child or parents wants to see their kid hospitalized for ANY virus or respiratory illness

Kid also valued
The ones with ' underlying conditions '.

May need to archive CDC report historical records at some point

Screenshot Maarten De Cock Twitter post 2023 " In 2015 @WHO report CO2 meters were recommended ' to inform teachers about IAQ conditions and prompt them to take measures improving ventilation.....it is therefore even more incomprehensible WHO never mentioned CO2 monitoring in a COVID 19 Pandemic " Not only did the 2015 @who report recommend teachers use a CO2 monitor it also mentioned Insufficient ventilation is associated with increased infection risk due to accumulation of viruses CO2 is a key parameter 1000.
