Hi Dr
I was talking about classrooms which IMHO are in the lower risk catorgory but which mostly have evaporative air conditioning units which have that dangerous breeding tower, which has been responsible for most of the Legionnaires' disease outbreaks
Plus the fact that windows may open but are they opened, do the staff know of the correlation between fresh air and covid laden air
Also specifically class rooms as IMHO there would be very little benefit for children trying to learn with masks and safety glasses on all day
Like wise there is no discussion about safety glasses, the eyes are of course are another source of entry for the virus
