Interesting that New Mexico, Texas, and Arkansas, and Louisiana have all had an uptick in new daily infections in the aftermath of the Fed 13 thru 16 storm.
I attribute that to an alteration of personal behavior by the populace of those states. When the extreme cold struck basically everyone stayed inside. Being southern (warmer) states, people normally don’t stay indoors continuously for days in mid-February. The extreme cold altered normal behavior patterns.
The more people are compacted into closed sealed spaces in which they ordinarily would not stay for days, the more the virus spreads.
Now that the weather has returned to normal, and thus personal behavior has returned to normal, new daily infections will return to their previous downward trend.
