gracious enough to bring to our attention...in that report there are several references to the effectiveness of masks...like this one...
" Finally, the fact that face mask directives have been more effective than either lockdowns or social distancing in controlling the spread of COVID-19 (22, 33) is consistent with indoor airborne transmission as the primary driver of the global pandemic."
COVID-19 is still "alive and well" in the U.S., and over 100 million of us are unvaccinated...we have a responsibility to do all we can to defeat this deadly virus...for all our sakes.
Feel free to read the entire report...then get back to us on whether or not you still believe that mask wearing is "just political signaling"...or not, depending on your capacity for "accountability".
