Similar arguments have previously been made for HIV prevention strategies , motorcycle helmet legal guidelines , seat belts , and alpine snowboarding helmets . However, opposite to predictions, threat compensation behaviors have not been vital at a population level, being outweighed by increased security in every case (one hundred, 102⇓⇓–one hundred and five). Polling and observational data from the COVID-19 pandemic have proven masks sporting to be positively correlated with different preventative measures, including hand hygiene , physical distancing , and decreased face touching . Three preprint papers reporting observational data suggest that masks may be a cue for others to keep a wider physical distance. One category of proof comes from laboratory research of respiratory droplets and the ability of various masks to block them. An experiment utilizing high-velocity video found that tons of of droplets starting from 20 to 500 micrometers have been generated when saying a simple phrase, but that almost all these droplets were blocked when the mouth was lined by a moist washcloth.

Gov. Tony Evers issued a new masks mandate Feb. 4 after state lawmakers voted to strike down his prior public health emergency orders. The Republican-led legislature contends Evers, a Democrat, overstepped his authority by repeatedly issuing pandemic-related emergency orders with out lawmakers’ approval.
