> The steady state is exactly 1, which is like balancing a pencil on its point. At exactly one, it's indeterminate; you could see a subexponential growth or decay. With no exponential terms remaining, lower-order terms that are ordinarily hidden by exponential growth become the dominant observables. (Since epidemic spread is also random, you're much more likely to see the stochastic terms show up in the overall stati…

We're not talking about a single flu season, effectively we're talking about skipping an entire flu season. Influenza is pretty promiscuous. In normal conditions, very few people aren't exposed to it: either their existing immune resistance (vaccinated or otherwise) is up to the job, or it isn't. Mutation is therefore the primary driver of flu, year upon year. This is why vaccines are continually reformulated for a b…

People don't inhale 1 or 0 covid particles they inhale n particles where reducing the value of n makes transmission less likely. Keeping more of your spit to yourself reduces chance of transmission even if masks are imperfect.

While I have two myself, I am the first to say it: Children are disease carrying vermin

My phrase is "The world is a filthy biological soup", so the less we're in the world, the less covered in soup we are.

There's a reason a lot of epidemiologists I know, myself included, are fond of the phrase "fecal patina"

Stomach viruses. Where in the world are you? No, seriously - where? Because here in the United States people don't wash their hands before eating. It's fucking gross. I always sanitize my hands with alcohol pads before eating out - ALWAYS. But the others grab subway poles, handles, those nasty menus, and THEN they grab that sandwich with the same hands . If anything should come out of this pandemic, it should be Amer…

A norovirus will laugh at your hand sanitizer, as will most other non-enveloped viruses.

This. Norovirus considers most hand sanitizer people use a threat in the same tone we commend 6 year old t-ball players for their "Good hustle".

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.

We have extensive sentinel surveillance systems and reporting physicians that, you correctly guess, are used to inform population-level estimates. Flu surveillance is probably the most comprehensive and robust disease reporting system we have in the U.S. outside the things that are mandatory reports (and even likely some of those).

>> there will be considerable political pressure to "do something" about the next flu wave. This must be resisted Why on earth does it make sense to resist sensible public health measures to reduce the influenza to R0 The measures would not need to be nearly as drastic as those for COVID ("normal" R0 of 2 vs 2.5+), so more handwashing (good to minimize a broad spectrum of pathogens), masks (already culturally ordinar…

Those measures are not entirely different from the measures previously suggested, though. Obviously your quoted poster’s concerns are less about “hand washing”, “wear a mask if you have symptoms”, and “stay home” while you recover, and instead are about an overreaction in which entire businesses are forced to shut down, children without symptoms are forced to wear masks even as they run and play, and people are forci…

We will be lucky if we can normalize washing your hands more and staying home when you are sick. The idea that we are going to react to flu with fanatical zeal and need to prepare to resist public health measures is a fantasy promoted by those who are preparing to fight a war that exists only in their own heads.

This year was a great experiment in person hygiene. It was the healthiest I have ever been for a full year, no colds, stomach bugs, anything. I'm not sure which practices I'll continue, but its definitely shown me that I have wayyyy more control over my health than I previously thought. Curious what others think are the most effective continued practices. Seems like social distancing isn't super reasonable, but maybe…

Have you been sleeping more because of WFH? That could be the major factor here.

I got sick 4 times in 2019 and am normally sickly for about 90 days a year. Sick 0 times since Feb 2020 and almost no "feeling shitty" days. The major change was hand washing, face masks, no bars, no gym, no movie theaters, and no travel.

For the first time in my life I feel unstoppable.

Well, yeah, they can be asymptomatic, spread their sickness to other kids, who then take it home to their parents and grandparents.

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).

Washington state has a tax funded state paid sick leave program for anyone who has worked at least n hours in the prior year and paid into it.

Focusing the "child" cutoff at ten seems dubious. Why not set it at an age that includes school extra curricular activities? :(

As a parent of a 6 year old and 8 year old, I'm thankful for this cutoff. Many studies define child as <= 18 or < 20, and I'm not sure how relevant they are for our particular situation.

I'd prefer both. There is a meaningful difference in both compared to the rest of the world.

Similarly, nursing homes and any other assisted living makes sense as a category.
