Barry, John M. - The Great Influenza, Parts II and III
Sun, Apr. 26th, 2020 11:16 pmThis got much more interesting once Barry stopped talking about assorted scientists with very little context and finally starting providing actual context for the 1918 pandemic!
Part II, The Swarm, covers viruses in general and how they work, and the influenza virus in particular. The H and N in the various influenza virus names (H1N1, H5N1, etc.) are hemagglutinin and neuraminidase, the two antigens on the virus. They occur in a ton of different shapes, each with subtypes, and the influenza virus also mutates extremely quickly because it's an RNA virus. (The RNA means there is less double-checking than there would be if it used DNA to replicate itself.) Influenza viruses originate in birds, and they probably migrate to humans via intermediary animals like pigs. One theory is that pigs have some receptors that can bind to bird or human viruses, so they can be infected by both, and the viruses mix their parts together.
If you can't tell, I found this part much, much more interesting than the assortment of scientists from Part I. I did, however, want to know if you are immune to all H1N1 influenza types if you have gotten one. It sounded like even after the numbering of the Hs and the Ns, there were still subtypes, but I couldn't tell how distinct those subtypes were, or if the main difference was in which shape of H and N the virus has.
In "The Tinderbox," Barry gives an overview of the US's entrance into World War I and how it mobilized various civilians, medical experts, and etc. Herein Welch reenters the picture, although I still can't quite say what he did. It's particularly weird that Barry emphasizes all these great scientists, because I feel in a later part, he basically has to detail how they all go down the wrong path when trying to research influenza. The poor nurses only get a paragraph or two, and they get blamed for a shortage in nurses because they consistently refused to let some of the doctors enlist "practical nurses," who would have less training than "graduate nurses."
I feel there is a whole book here on doctors vs. nurses and the status and respect (or lack thereof) given to nurses, but clearly Barry is not interested. Boo.
There's also a lot about censorship in the name of the war effort, which will come into play later when the pandemic kicks off.

Mon, Apr. 27th, 2020 06:27 am (UTC)If you have antibodies to any particular strain of H1N1 (via illness or vaccination), you are more likely to be immune to other H1N1 strains, but it mutates so quickly that there's no guarantee (as in the swine flu H1N1 in 2009-10, which previous H1N1 vaccination did not affect, so they had to rush out a new additional vaccine). H3N2, the most common A-type influenza in humans, changes even faster. That's why every now and then there'll be an influenza that has little effect on a particular age cohort who have been previously exposed, while it hits people a decade younger hard. It's not that they've been exposed to this particular H1N1 necessarily, but that the version they had is close enough to the current one that it gives them some immunity.

Oh, and I was also really interested in the nurses. They continue to get short shrift, alas.

Mon, Apr. 27th, 2020 08:23 am (UTC)I.e. there was a lot of status anxiety going on within nursing quite apart from their problems vis a vis docs.

Mon, Apr. 27th, 2020 08:19 pm (UTC)There was certainly a thing of upper-class women opening up their stately homes as nursing homes for officers, without getting into the hands-on stuff themselves, but what VADs encountered was often a pretty brutal shock - Vera Brittain and Naomi Mitchison both wrote of what it was like for the sheltered and ignorant middle-class young woman suddenly plunged into war nursing.
On women doctors, there is a new book on the Endell Street Hospital just out, by Wendy Moore, which includes something on the flu epidemic phase. But not sure what happened with the women's hospital units in France, Serbia, etc.
