There is much variation between states, as seen on
CovidActNow. Many northern states such as South Dakota and Wisconsin have seen large drops in cases, deaths and ICU hospitalizations per 100k population, while CA, TX, AR, GA and FL are still seeing increases. I'm not sure how to explain the timing of these waves, but there was clearly an early wave (NY), a July wave (FL), a November/December wave (WI, SD, etc) and Dec/Jan wave (Many southern states and MY, MA). On the CovidActNow website, multiple states, counties and cities can be compared over time.
