There are some really interesting things you can observe from that data. There are some states where the ILI numbers are clearly significantly different in 2020 compared to other years if I look from week 1 - week 10 only. These are states where it may have been much earlier:

California, Colorado, Connecticut (is crazy high compared to most year), Illinois, Maryland (also crazy high compared to most year), Massachusetts, New York, North Carolina, Tennesse (crazy high), Washington, and Wisconsin. I'm very interested to see the antibody results for these states. Other states have outliers as well, but these were the most significant.

But for every state 2020 is near the top, even if they aren't outliers. Some states had a really bad year in 2018 and 2019 as well. Whether that was flu or something else (like the covid-19 virus but less dangerous) we may never know.

Anyway, I'm too lazy to figure out how to post my graphs.

But thanks again for posting the link to the data.
