Are we on the verge of a second wave of coronavirus infections? Is there a spike in infections in states that reopened first?
The only way to answer that question is to watch as the data roll in. Arguably the best data to look at to see if a second wave is beginning are the hospitalization numbers. The media frequently reports the biggest and most dramatic numbers, often devoid of context. The number of cases has been reported regularly since the early days of the pandemic, and yet we know that the number of cases
can be misleading.
As more people are tested and re-tested for the virus, more results will come back positive, with the current number of confirmed cases exceeding 2 million in the U.S. But if we know anything, it is that increases in the number of confirmed cases do not accurately convey how quickly and widely the virus is spreading.
Antibody tests and even the
examination of sewage in some cities suggest that the number of infections is likely much higher than the number of confirmed cases.
But on the other side, some of the confirmed cases are
double-counted in some states partly because both antibody and active virus tests are being counted separately but then combined in the total number of cases. While the antibody tests have been
criticized for their false positive rate, another criticism has been that the antibody studies can
underreport infection rates because they are not sensitive enough to detect a past mild infection.
Overall, because the bulk of testing is focused on people who are the sickest and who face the greatest exposure, it seems reasonable to conclude that the true number of U.S. infections is substantially higher than the reported figure. But an attempt to estimate the true number of infections would be little better than a guess.
And this presents a problem with the daily updates. To say that a particular state or city is seeing a “spike” in cases is to say that recently they have had an uptick in positive test results. That could be due to more testing and more ways of testing, or it could be a hint of growth in the infection rate.(READ MORE)
