ALL,

The subject study is "hot-off-the-press" and is worthy of your consideration.

SUMMARY: https://www.cdc.gov/niosh/docs/2021-107/default.html

This summary has PDF Link so you can read the entire report (attached below).

REPORT: https://www.cdc.gov/niosh/docs/2021-107/pdfs/2021-107.pdf?id=10.26616/NIOSHPUB2021107

The Bottom Line : "These finds have important implications for guidance on source control and mitigation."

It maybe possible that this will open up a blocked avenue of RPE.

After review, I certainly welcome your comments.

Be Safe and Stay Healthy!

All My Best and Happy Holidays,
