Something to Remember About Those Flu Deaths

I'm quoting from a longer post about the pandemic on the Weekly Sift, which was summarizing and quoting from Dr. Jeremy Faust in Scientific American:

The flu comparison is even less appropriate than the numbers make it sound. In Scientific American, Dr. Jeremy Samuel Faust concludes that the comparisons we hear about flu deaths vs. Covid-19 deaths are misguided.

When reports about the novel coronavirus SARS-CoV-2 began circulating earlier this year and questions were being raised about how the illness it causes, COVID-19, compared to the flu, it occurred to me that, in four years of emergency medicine residency and over three and a half years as an attending physician, I had almost never seen anyone die of the flu. I could only remember one tragic pediatric case.

He began asking other emergency-medicine doctors, and found that their memories match his. They remember lots of opioid deaths, gun deaths, and traffic-accident deaths — which are supposed to happen in similar numbers — but not flu deaths. Flu death totals, he came to understand, are not counted deaths — deaths of particular people whose doctors write “influenza” on their death certificates — they’re extrapolations based on models. The models assume that many people die of the flu outside of hospitals, and aren’t officially counted.

In the last six flu seasons, the CDC’s reported number of actual confirmed flu deaths—that is, counting flu deaths the way we are currently counting deaths from the coronavirus—has ranged from 3,448 to 15,620, which [is] far lower than the numbers commonly repeated by public officials and even public health experts.

In other words, (and I’m commenting here, not quoting or summarizing Dr. Faust) the flu death totals we usually hear are more comparable to the Covid-19 death totals we’re starting to get from excess-death demographic models — which show much higher numbers than the 65,000+ you commonly see reported. But if we compare counted Covid-19 deaths during the second week of April to counted flu deaths during the worst week of an outbreak “we find that the novel coronavirus killed between 9.5 and 44 times more people than seasonal flu.”
