This should not come as a surprise, and it was largely predictable from the outset. The flu has a base reproduction number (R0) less than 2 ( https://www.vdh.virginia.gov/coronavirus/2020/12/07/covid-19... ). Covid has an R0 in the vicinity of 2.5 ( https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scena... ).

Will the flu come back after covid ends? If covid ends?

Yes, the flu virus has a natural reservoir amongst the bird population.

Damn I wish I had your immune system. Pre-covid I would get sick every September and probably 2 other times in the year (I would have the flu jab every November too!). I'm a germaphobe so wash my hands before eating, etc. I also try and stay fit, don't smoke and hardly drink alcohol. Unless there's a trick I'm missing here?

Just a thought — the trick might be trying to be less of a germaphobe to build up your immune system (not medical advice).

Also not medical advice, but since I stopped being a germaphobe in 2016, I haven't gotten sick. Maybe it has to do with being less stressed in general, too.

YMMV :)

You can do a LOT. I haven't been sick once in 6+ years because I do the following: 1) Almost never eat out. Home cooked meals that I've prepped / washed. This was single handedly the biggest factor that completely removed "getting sick" from my life. 2) Hand wash before touching face, or food. 3) Avoid sick people. If I hear someone coughing or sneezing, I move away from them. Call me a germ freak, I don't care, I've…

I don't "know" for sure that it was, just like I dont "know" that ANY of these factors had anything to with me not getting sick. Maybe, it was all just luck.

That said, I've been pretty good about hand washing and avoiding people my whole life. Having grown up in a medical family, personal hygiene was not something completely foreign to me. As a result, haven't had a history of being sick regularly, but it still could/would happen from time to time.

It was after I stopped eating out that I completely stopped getting sick. I am not exaggerating when I say that in the last 6 years, I have been sick 0 times. That correlates perfectly with me stopping eating out. Correlation != causation, I know.

How about a culture and social support system where you can just stay home and rest if you feel something's up? Probably a lot more efficient than a mask, and would probably help with lots of other problems as well.

Plenty of people, hourly, gig, and self-employed people don’t get paid if they don’t work. You might be able to force some of those to be paid while sick-not-working, but the last category will be very difficult to address without either missing a lot of folks or creating tons of fraud and grift risk (and represent a lot of interactions with the public).

I think this goes under culture and social support system. Perhaps worth a thought that giving more support for everybody can help everybody. This interaction is quite apparent in e.g. epidemics, but probably has similar effects for many phenomena.

I remember reading a conspiracy theory back in ~ April 2020 that said "what happened to the flu" / "why are flu cases down so sharply?"

It was literally so stupid that it took me a minute or two to understand that the implication was that conspiracy theorists think flu cases were being categorized as covid.

If I caught the flu, how would the government/scientists studying this stuff even know I got it? If you're anything like me you probably just take some time off and get over the illness without ever seeing a doctor or taking a flu-test. How do they measure such things? I suspect they use some elaborate statistical model to try and generalize the results to the whole population.

Well - I imagine something like the Seattle Flu Study where volunteers answer questions and get samples taken if they are sick.

I was just commenting to a co-worker my entire family hasn't been sick since the pandemic started. That is very unusual for a family with young children. No flu, no stomach viruses, absolutely nothing for more than a year now. Thankfully no covid-19 either.

Due to T-Cell immunity, a max of 20% of the population was ever going to catch the CV19 version of the flu anyway. Its obvious at this point the reaction was extremely disproportional to the risk.

I'm interested to know more, do you have any sources on this?

By the way, now that we are already talking about R ~= 1 ... Over pretty much the last year you could observe, in different countries all around the world, that the reproduction number was 'magically' floating around 1. Only recently did I learn that this effect was puzzling for epidemiologists as well and was only solved around 2012 (?) in a model that assumes a network of information about the disease in parallel t…

A well-known Norwegian economic commentator pointed this out in a newspaper article a few weeks ago. You'll eventually be forced to maintain an R~=1 no matter what you do, so it's best for everyone if your cases have a low baseline when that happens. The measures will be the same, but the baseline risk can either be terrible or okay. You can almost see the phenomenon in real time during this pandemic. Countries that…

The economic deviation caused by governments over reacting is your biggest pressure. Unless you shut down all travel, bars, restaurants, schools, universities and dating.

Then all of this will come back in the future and kick you in the teeth. Either we're going to have to accept this as a way of life, which is more detrimental. Or we're pushing off the inevitable.

Yeah but there are numerous studies that show these things don't work. Also, I'm confused why you think someone cannot get both covid-19 and the flu.
