New highs in many states again today, I went in to town earlier today and saw a few out of state tags, a major highway runs nearby there, many travelers stop in that small town frequently...Fortunately daily deaths have not spiked but new cases sure are jumping...
The trouble is testing capacity and testing activity is increasing, so more cases are discovered regardless of what the virus is doing. The infection is active in the body for two or three weeks but can still potentially result in a positive PCR test months later (to give a prominent example, George Floyd tested positive for SARS-Cov-2 on the third of April, and again at autopsy after his death on the 25th of May). Therefore if someone tests positive, it does not necessarily mean that they have an active infection that they caught recently.
The count of deaths is a better indicator of disease spread, although it is a delayed indicator of the number of new infections by about three weeks. The number of hospitalizations for Covid-19 is perhaps better still, if it is available, as it is delayed about a week less. However, there are reports that the virus may be tending to become less virulent, and so may lead to a lower mortality rate, and thus making the same assumptions about the ratio of deaths or hospitalizations to the number of infections as were made two or three months ago might be incorrect.
