I got a few questions on that thread about particles floating. Here's a quick explainer although of course there are plenty of air experts on here as well, so I will try to do a with a lot of pictures to be different.
Historically, humanity has had two major theories of disease spread: miasma (arises in swamps and floats in air) and contagionism (disease spread by contact between people).
In the 1800s we learned about germs, and that they live in us, and that we spread them.
Maybe medical officers of health (MOHs) need to be reminded of what the Ontario Medical Association thinks their role is:
"Guarding the Health of Citizens".
Hmm.
And all I'm doing is clearing out old PDFs. Imagine I started making a case for their abdication of their duty?
It's almost comical
This report is entertaining to me because it's the OMA lobbying for more jobs. They encouraged the maintenance of all the local community boards and that there needed to be an MOH (who are very well paid) in each one. The opposite of what SARS Commission said was needed.
