    What research papers have been published with all variables showing that face coverings prevent infection, and people who did not wear anything suffered permanent health damage? I’m not asking statements, but published papers that definitely show that wearing something prevented spreading, and people who didn’t caused the spreading. A news story is not acceptable, only scientic journals or papers to read through the methodology and results.
