A person gets a cough, a fever, fatigue. Ordinarily, that doesn’t engender much alarm. But this year of COVID is different. Almost anyone with those symptoms believes he or she might have it. Depending on the state or city, and depending on the severity of symptoms, many of them manage to secure a test. And the majority of them test negative for COVID.
There are also a lot of people who had similar symptoms earlier this winter and are convinced they had COVID back then. Maybe they did. But maybe they didn’t.
Actually, even now, chances are better that it was actually old-fashioned influenza. Flu can kill, too, but it infects tons of people and kills a very small percentage of them. For the vast majority, flu is a bother and a pain and nothing more.
So far this season (2019-2020), flu has infected many people, almost certainly way more than COVID (which so far appears to have a higher case fatality rate, although exactly how much higher has yet to be determined). Take a look at the CDC page for this year’s flu in the US, and see the kind of numbers I’m talking about. It says 39,000,000 – 55,000,000 cases of flu, 18,000,000 – 26,000,000 doctor visits, 400,000 – 730,000 hospitalizations, and 24,000 – 63,000 deaths.
It adds this:
Because influenza surveillance does not capture all cases of flu that occur in the U.S., CDC provides these estimated ranges to better reflect the larger burden of influenza. These estimates are calculated based on CDC’s weekly influenza surveillance data and are preliminary.
Influenza testing across the United States may be higher than normal at this time of year because of the COVID-19 pandemic. These estimates may partly reflect increases in testing in recent weeks and may be adjusted downward once the season is complete and final data for the 2019/20 season are available.
I wonder whether levels of flu have been going down since all this social distancing began, though. It seems logical to conclude that would be so.
