The first ecological study of state mask mandates and their use to include data from the winter case spike has found that widespread mask-wearing likely didn't slow the spread of COVID-19.
The study, conducted by the University of Louisville using data from the Centers for Disease Control and Prevention, found that "80% of US states mandated masks during the COVID-19 pandemic," but while "Mandates induced greater mask compliance, [they] did not predict lower growth rates when community spread was low or high." The study also found that "Mask mandates and use are not associated with lower SARS-CoV-2 spread among US states."
"Our findings do not support the hypothesis that SARS-CoV-2 transmission rates decrease with greater public mask use," the study said, as reported by Townhall's Spencer Brown.
British clinicians have reported masks to increase headaches and sweating and decrease cognitive precision.
In summary, mask mandates and use were poor predictors of COVID-19 spread in US states.
Strengths of our study include using two mask metrics to evaluate association with COVID-19 growth rates; measuring normalized case growth in mandate and non-mandate states at comparable times to quantify the likely effect of mandates; and deconvolving the effect of mask use by examining case growth in states with variable mask use.
The recommendations do not apply to those who have not been fully vaccinated or to those inside "Homeless shelters, corrections centers, health care facilities or in places where masks are required by law," Quintanar reported.
