The US is a big place. Might want to break it down more regionally.
In Texas, infections have definitely spiked since Memorial Day (roughly when Gov Abbott started opening things up) but not all the way back from May 10. Hoping not to see the 2-3 week lag in deaths, but only the next week or two will tell.
Arizona, Florida, and Arkansas appear to show a similar spiking trend since Memorial Day, rather than a whole month. Rising cases starting in earnest 2-3 weeks ago and hopefully not a connected spike in deaths over the next couple weeks.
If this is the case, then there have to be other states are showing a decreasing case count to have an overall stable number. I would think it’s probably biased by New York/New Jersey/Pennsylvania.
When combined with numbers from other states, it could well be the number of cases has been steady over the last month for the nation as a whole, but that’s a decline in some areas and a rise in others. Even with states, some regions (city vs rural) can show different trends.
Likewise, since deaths lag infections, the total for the nation as a whole is less informative unless there’s a uniform rise/decrease in infection everywhere, which we know is not the case.
Also, unfortunately, there’s less uniformity between states in counting deaths than one might wish. Some states only count confirmed COVID deaths, while others include estimates of probable deaths, which is what the CDC recommends. That can skew the numbers you might get if a spike occurs in a state that only reports confirmed deaths.
Worldometer includes information on how it collects statistics, and that’s worth looking into for context. It’s a nice site for an overall picture but definitely be careful about using a single number to get a nationwide picture for the US. Likewise, some of the comparisons between countries have similar known issues (different counting methods and such) so take those with the appropriate context.
