The three-part challenge, regarding masks and SARS-CoV-2.
Part 1: Mask advocates need to show that the virus is infectious in aerosols. Find a study where it can be cultured after being picked up out of the air in aerosol (not large drop) form.

As for my part of that challenge, here's a study showing that it was detected, but did not produce results in culture. Could it with more testing? Maybe. Can you show it can? Not yet.

Part 2: Mask advocates need to show that surgical style masks offer significant protection from aerosolized (not large drop) spread of respiratory viruses.

For my part, I offer two studies. They do not provide significant protection.

Part 3: Mask advocates need to show that homemade masks offer significant (if any) protection from aerosolized (not large drop) spread of respiratory viruses.

For my part, I offer this study. You may have seen a chart of the materials tested (including vacuum cleaner bags) tested. The study ends with the suggestion that homemade masks not be used.

Your move, mask advocates. So far, the CDC seems to have served us up more specious suggestions to go along with the suicide pact of a lockdown plan we've been forced into. If you can provide evidence for those three things above, we can talk ubiquitous masks.
