I love this. Explainer: There are 100 outcomes (all squares) each equally likely. Wiggly lines event happens 20% of the time; grey event happens 30% of the time. >

Incidentally, in my experience this is the ultimate way to tell an arts nerd from a stem nerd. Arts nerd like the aesthetics of the left side, stem nerds like the logic of the right side. Linguists, being right at the periphery, refuse to choose sides.

Poultry farm density and proximity drive highly pathogenic avian influenza spread - Communications Biology A study using phylodynamics to investigate highly pathogenic avian influenza (HPAI) H5N8 spread in southwestern France in 2020 and 2021 demonstrates that a single introduction led to rapid spread, mainly in duck farms, with farm density driving transmission.

Learn to love the Moat of Low Status It hurts, but less than you think

Recently came across the really useful term 'Moat of Low Status' from Cate Hall. It describes why we find it so difficult to take steps required to fulfil our ambitions - if we're already good at one thing, it's hard to endure being bad at something else.

Whether it's Democrats making it harder for kids to get cigarettes or Republicans making it harder for kids to get vaccines, both sides have imposed the will of government on America's children.

Bsky is so disseminated that you never know who is seeing what. So I want to be sure that people see that the foremost public and global health law theorist in the US, Lawrence Gostin of Georgetown Law, is here on Bsky and doesn't have nearly enough followers. Fix that, folks.

The most important takeaway: this is *not* a situation where reaction will be sufficient. If prevention measures failβ€”and by all current appearances, they appear to be heading in that directionβ€”the human, animal, and economic toll may be staggering. 7/7

Vector-borne epidemics tend to explode once a threshold is crossed. Individual livestock cases will go unnoticed until there are simultaneous outbreaks, and by the time an infestation is noticed, multiple herds in a region will be affected, requiring a large coordinated response. 6/7

Look at West Africa’s battle with Old World Screwworm since 2023: 1000s of cases, freq wound care and anti-parasitic administration, huge cross-sector response… Btw, there isn’t an approved treatment for NWSβ€”all parasiticides would be off-label. Veterinary demand alone would be staggering. 5/7

What human health tolls? Agriculture is already one of the most stressful occupations, and no shortage of studies show the *intense* physical and mental health toll epizootics have on farmers and ag workers. 4/7

Texas is home to ~12 not 7 million cattle. Herd sizes and production systems in the report are outdated, there's no trade disruption, it assumes rapid SIT deployment, doesn't include response costs, etc. I'd venture† the $1.8B figure is off by *an order of magnitude* (at least in final costs) 3/7

Economically? NWS isn't just loses to cattle futures. The USDA economic estimates are a useful start, but the (conservative) conclusions were extrapolated from data from *50 years ago*. 2/7

Screwworm is making headlines because of this rare imported human case, but a slightly important omission from these articles is just how *insanely catastrophic* a New World Screwworm (NWS) epidemic would be on people, livestock, pets, and the US economy. 1/7

The CDC shooting was public health’s Jan. 6 β€œIn RFK Jr.’s America, it will never be safe to practice public health or medicine," write an epidemiologist and a former CDC staffer.

NEW: The CDC shooting was public health’s Jan. 6. from @colincarlson.bsky.social and myself for @statnews.com. we do not make this comparison lightly, and we bring the receipts.

Love all those calligraphic letters we get to use in stat formulas. I hope other disciplines get to experience the joy of writing a fancy Y rather than the regular boring one.

Opinion | Jay Bhattacharya: Why the NIH is pivoting away from mRNA vaccines As a vaccine for broad public use, mRNA technology has failed to earn the public’s trust.

This op-ed from NIH director Jay Bhattacharya is *infuriating*. He says we have to stop funding mRNA vaccine research because it hasn't "earned public trust." Motherfucker, WHO DID THAT.

Bird flu is spreading a LOT in dairy farms now in US- now is the time for surveillance and stepping up action on vaccine- but US has Kennedy who seems to think infections are fine and has cancelled the contract for developing a mrna bird flu vaccine
