Footnote to tonight’s notes... defeatism here is not just me. I’ve heard a popular theory that the century of gains against infectious disease was entirely based on temporary victories. Individual battles are won but the war overall gets harder and we are steadily losing ground.

So if there’s a second winter wave if Covid and there’s a civil war after the election, we have a mutated worse strain to look forward to. Yay. This story just gets relentlessly gloomier as a precedent for 2020.

More detective work. Drift rates in the virus suggest the North American origin story is most likely. Research by Michael Worobey of U. Arizona in 2014 showed 7 of 8 1918 H1N1 genes resembled flu genes found in North American birds.

This is fascinating. Apparently horses rather than birds used to be the main flu reservoir. There’s a chance mechanization/cars and the retreat of horses from human life made birds the reservoir. Very circumstantial evidence but I like the story.

There is some tricky inside baseball here about 8th gene and the W shaped mortality curve. I’m not going to try and follow the intricacies here. But the level of detail that detective work uncovers is astounding. I didn’t know flu research was so broad deep. Good work Science!™

2 more flu epidemics in 20th century, 1957 Asian flu H2N2 and 1968 Hong Kong flu, H3N2, both share a lot of genes with H1N1. Apparently humans gave the flu to pigs, not the other way around. Swine flu should be called long pig flu.

We stop here for tonight and reflect on the grim fact that coronaviruses are not flu viruses so a lot of this does not apply. But we have a sense of the learning curve involved.

Chapter 15: the human factor. Apparently there was a lot of variation in who died across age and time. Age mortality had a W shape with a peak for adults and also very young and very old, already covered in previous chapter... complicated. Now geographic.

Asia and Africa had the highest death rates. Some areas 30x the west. Persia seems to have had the highest rate at 22%. Undivided India highest absolute numbers, 13-18m at 6% fatality rate. Possibly higher than WW1. I’m guessing some of my great grandparents generation got it.

Mostly boring survey here of patterns similar to Covid, correlated with wealth, class, caste, bring immigrants etc. Eugenicists casting aspersions at “inferior” races being weaker etc. Interestingly blanks in the US appear to have been less susceptible in 1918 unlike 2020.

Mask wearing and banning of mass gatherings cut death tolls by up to 50% in some cities and the US was better about this than Europe. Woodrow Wilson vs Trump would be an interesting comparison. Has anyone done one?

Mostly men died at greater rates except of course in India where these things always flip. TB was a big comorbidity. It’s weird to think about how TB was such a huge thing back then. Like diabetes today.

It’s kinda grim that so many segments of this book are boring through no fault of the author. We’ve all learned this stuff more directly. We’re in the reboot of this movie. Well that’s it for tonight.

Here we go again. Chapter 16, “the green shoots of recovery” Bad news: took between 1922-26 for the Spanish Flu to truly recede, basically culling the population of the weak. Sorta good news? there was a baby boom after as the healthier ones went for the demographic dividend.
Show this thread -
In general the world got healthier from the cull. Especially men. But babies conceived during the flu, and exposed to it prenatally were weaker, and had poorer life outcomes. Many adults who got it had chronic conditions after, just as already seen for Covid. Darwinian

We’re only now seeing Spanish Flu effects erased as the last of those born during it die. The acute phase of the disease often had anxiety attacks and suicidal behavior. The chronic phase often had lingering depression.

In Norway, 7x higher asylum admissions related to flu every year in the 6 years following the pandemic. It’s going to be 7x the fun till 2026 people.

Tanzania had a famine because people were too depressed to plant stuff. General high incidence of “sleepy sickness” encephalitis lethargia, EL, 1917-25. War+flu I guess. A third died within weeks, a third recovered, a third went on to develop Parkinson’s-like paralysis.

The causal link is unclear but it seems these were the Oliver Sacks’ L Dopa patients in Awakenings. Damn.

We end this chapter with the story of a Xhosa woman, Nontetha Nkwenkwe, who started a religious movement out of her Spanish flu visions and ran afoul of the white state that saw her movement as subversive, and kept putting her into an asylum till her death https://en.m.wikipedia.org/wiki/Nontetha

This chapter rhymes the most witch Black Death aftermath. Mental illness, long-term social malaise, cults... Not pretty. The core of it seems to be extended post-viral fatigue syndrome and complications, compounded by unraveling societies where the toll was high in % teens.

We stop here tonight. That chapter totally bait-and-switched. “Green shoots of recovery” my ass. That was more “red veins of long-term damage.” Repent ye sinners. 7 years of pain are upon us.

This is the least entertaining of the books I’ve read do so far, but the most reality checking. It’s like reading a travel book about a country by a foreigner after being blind-teleported there. She’s the expert, but all of us now know more than she did when writing this.

This chapter is about what-ifs of interrupted lives. Survivor lives that turned out different due to someone close dying. Insurance companies paid out $100m ($20B today). One death was Trump’s grandfather. The real estate slumpire started with his Spanish Flu insurance payout

Due to prime-of-life fatalities many breadwinners died. In Sweden, for every death, four people ended up in the poorhouse. Do we have poorhouses anymore?

Countries like a France and UK passed adoption laws soon after the flu, possibly due to flu orphans. 500k orphans in South Africa alone
. Black ones didn’t do so great.
20 languages went extinct in Vanuatu which apparently now still has 130.
Some Alaskan tribes crippled.Show this thread -
Baby boom + orphans in 1920s. States with highest death rate had highest growth in per capital income after

Yupik word: nallunguarluku, “pretend it didn’t happen.” Apparently elders advise young people to do that to their recent history. Looks like the Spanish Flu was the last of several epidemics that destroyed their way of life completely. Welfare-alcohol spiral.

A lot of people are going to have to nallunguarluku 2020. Not me I think. The flu culled not just physically vulnerable individuals but demographically vulnerable cultures and languages. Wonder if it happened in civilizational core. Like music or literary scenes culled.

Next chapter, science and anti-science. The flu caused backlash against germ theory triumphalism, and alt medicine types claimed higher cure rates and grew in popularity and legitimacy after. Le sigh. Expecting an anti-vaxx spike myself, post-Covid.

That was a quick chapter. Back to nature movements, loss of faith in Victorian science but rise of more modern ethos. Kinda weak connection to flu as one of the causes. Medicine regained credibility with ruse of virology, antibiotics etc. Overall the flu created postmodernist.
