Thanks for your comment. I have looked into masks. I'm not sure what you mean by "dust masks," but surgical and other lower quality masks help with source control, I.e., reducing the amount of virus infected people exhale into the air. An uninfected person wearing a mask will receive a lower inhalation dose, which seems to lower the risk of serious illness. Everyone masking indoors lowers the amount of virus in the air and the amount inhaled. The result is collective lower risk. Combine masking with other mitigations (ventilation, filtration, etc.), and the risks are significantly lower. Higher quality masks like KN95s and similar models do a much better job than surgical masks. K95s and other models that include respirators are excellent when properly fitted.
I agree about the chat bots stealing but when you got to masks, you lost me. Please look into it more. They are dust masks, nothing more.
