But the "reference period" is defined by the report as the 20 days before mask mandates started. Immediately after these mandates were instituted, these declines were statistically significant..

Here's what it could mean for all of us. We infer that mandates likely did not affect COVID-19 case growth, as growth rates were similar on all days between actual or modeled issuance dates and 6 March 2021. "Their perspective on the study and results to me are contrary to what was stated in the actual study itself," Bisesi said.

Latest news. | Our study was also limited by the lack of information on accessibility of COVID-19 testing; if less accessible testing is associated with less mask adherence, the associations we report here may be under-estimates. We calculated the number of new cases in each month, for each state and D.C. Rates were the number of new cases divided by the population in 2019.

As of Aug. 3, Louisiana is under a temporary statewide mask mandate required of all people, including those who are vaccinated, when indoors. The opposite was true for states with mandates.

From the start of the pandemic through this spring, the cumulative rate of Covid mortality has been slightly higher in Sweden than in Germany (by about 15 percent), but the rate of overall excess mortality has been slightly higher in Germany (by about 8 percent). Odds ratios indicating protection against high COVID-19 rates remained for all months and policy subgroups, ranging from 0.82 to 0.93 for states with any policy and from 0.60 to 0.95 for states with no policy. Wearing a mask may still give some people a sense of security, but they could breathe more easily if theyd face the facts.

Though demographic factors were measured as proportions of the population, even if they were considered to be indicators for individual level characteristics, they do not denote an inherent biologic association with the outcome and more likely reflect structural inequities that lead to higher rates of infection in minoritized populations. One of the biggest problems in the United States so far has been the lack of a coherent, cohesive national response, said Wafaa El-Sadr, an epidemiologist at Columbia University. Outbreaks are comparatively smaller in states where efforts to contain the virus were stronger over the summer and fall potential good news for leaders taking action now.
