Response to Downgrade of PPE Precautions for COVID-19

OHCOW expert, John Oudyk, (an occupational hygienist with extensive experience in the issue e from research during and post SARS, MERS & Ebola) drafted a response to the federal and provincial public health proposed policy shift to downgrade the type of precautions (including masks) when the pandemic began, with updates several times since.  He has also presented on the subjects of transmission risk and worker protection numerous times as the pandemic, and science has evolved. Please note, that although funding to OHCOW is from the Ontario government, the views of the report(s) do not necessarily reflect the position of the Ontario government.
