Daily case and death growth rates before implementation of mask mandates were not statistically different from the reference period.
However, In the “Discussion” section:
Mask mandates were associated with statistically significant decreases in county-level daily COVID-19 case and death growth rates within 20 days of implementation.
Plus, unless I’m missing it, I don’t see a comparison to a control group, i.e. counties without a mask mandate. That means, the 1% decrease could just be because numbers overall were going down in the summer. If you look at the chart in figure 1, the line was already trending down before the mask mandates.
Yeah, it's data cherry picking and it's very unethical. They've done it through the entire pandemic. You have enough data sets across the country to support any conclusion you want.
Louisiana's data proves they don't work. Covid supposedly has a 5-10 day lag. Thus, any measures implemented should lag by 10 or so days. When we locked down in March, took ten days for cases to go down. When we established masks in June, cases peaked and dropped THAT DAY.
Wow did they make this report political.
In the actual report:
