That article is drawing conclusions based on an incomplete data set. Suicide with covid is a covid death anyway.

nope, having covid when getting run over by a bus counts as a covid death in many places

How many places? And how many places are trying to hide the real numbers(India the most recent one)

Would this only show up in the covid infected population?

Not necessarily. COVID might be so transmissible that the entire world has been exposed to it enough to trigger an immune response but only establishes itself and becomes an infection in those who get a large enough viral load over a short enough time period.

So light COVID exposure would produce enough of an immune response to trigger influenza immunity but not COVID immunity?

While I think this is most likely due to masking, distancing and staying home when sick, which were all far more effective against the flu than against SARS-CoV-2, I wonder how much this was affected by some of the deep cleans that cities were doing at the beginning of the pandemic where they basically sprayed entire cities with disinfectant trucks. Does anyone with more expertise have any thoughts about that?

In this 2018 paper[1] transmission from surfaces accounted for ~4% of flu infections. So it probably made very little impact.

This is stupid. Both my wife and I got sick and luckily it wasn't Covid. When we were tested, that's all everyone cared about so I'm sure they didn't mark us as having the flu even though we obviously had something.

Seems like they just need to show a % of positive influenza tests to control for a reduction in performing those tests.

im in your situation: didnt need to leave my house and minimally interacted with people outside of my bubble. I felt sick recently and got the covid/flu test.

Why?

Also may impact your future immunity. Good to know what your clinical history is..

The likely explanation is that, because the flu is significantly less transmissible than COVID, even states with "no restrictions" were able to knock it out because enough people took enough measures to protect themselves from airborne/surface communicable disease in general. In other words, you can probably beat back the flu significantly by having enough of the population mask up, wash/sanitize their hands, etc.

But the flu has always been here, even when our country was significantly less populated, when we were significantly more rural, and when people were significantly less connected in many ways. Like, how did we get flu pandemics in the 1700s? Weren't we less connected back then, even after you account for all the social distancing that was done this year?

The flu (influenza) has been linked to solar radiation and electricity.

-- quote --

In 2001, Canadian astronomer Ken Tapping showed that the influenza pandemics over the previous three centuries correlated with peaks in solar magnetic activity, on an 11- year cycle. It has also been found that some outbreaks of influenza spread over enormous areas in just a few days – a fact that is difficult to explain by contagion from one person to another. Also, numerous experiments seeking to prove direct contagion through close contact, droplets of mucus or other processes have proved fruitless.

From 1933 to the present day, virologists have been unable to present any experimental study proving that influenza spreads through normal contact between people. All attempts to do so have met with failure.

Just speculating here, but maybe because of false positives where flu cases get labeled as Covid? I've heard that PCR tests were not meant to be used for large scale virus detection. EDIT: The PCR test quote was fact checked and deemed to be misleading, but it still sounds like they are not very accurate [0]. [0]: https://www.reuters.com/article/uk-factcheck-pcr-idUSKBN2442...

Every COVID test I took included a separate influenza test. Not sure if that was the case everywhere though. But at least in my case flu would get labeled flu.

An alternative explanation is that of "viral interference"[1,2], i.e., the most transmissible virus boosting up viral immunity in the population, and precluding transmission of the less transmissible/fit virus [1]: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5489283/ [2]: https://www.thelancet.com/journals/lanmic/article/PIIS2666-5...

The lack of Flu infections in the population that did not contract COVID cannot be explained by viral interference. Viral interference would only explain a decreased influenza infection rate among those exposed to COVID.

If a large portion of the people who contracted COVID are removed from the set of people who could have potentially exposed me to the flu, doesn't that decrease the likelihood of me contracting the flu regardless of whether I contracted COVID?

I don't know where you live but in Canada we have programs like FluWatchers which send sample groups a survey every week asking about flu-like symptoms, flu vaccinations (and COVID now) and such every flu season. They can also request a voluntary sample from you to help track these things. So the data is there :-)

Interesting, I've never (knowingly) been a part of an epidemiological survey like that.

I was in university when the Ontario Health Study began and they were giving out Amazon gift cards for participating so naturally a ton of students signed up. They send out questionnaires to participants every few months.

Every community has a baseline mortality rate during "normal" times. During abnormal times like pandemic, famine and war, more people die than usual, but often the cause isn't known. If you subtract baseline mortality from actual mortality to get excess mortality, that's often a better estimate of the casualties from pandemic, famine and war than the death certificates for every person who died. Excess mortality in m…

Sorry for the awful formatting. Odd things in the prelim 2020 data that surprised me: All leading causes of death were statistically unchanged; COVID just shoehorned itself into the #3 spot below heart disease and cancer, above unintentional injuries. I was expecting a huge drop in the "Influenza and pneumonia" category, but there was not. I was also expecting a noticeable increase in the suicide category, but there was not.
