My profile picture honors Dr Wu Lien-teh & his pioneering work in Malaysia in 1910 on masking to prevent pneumonic plague. The French doctor Gérald Mesny who came to replace Dr Wu thought he knew better, refused to mask & died.

I’m not surprised.

I’ve run clinic after clinic (when working in Paeds) seeing exhausted parents with kids that “aren’t better yet”. And that was before C19.

Why are people surprised?

NB this is not just a UK thing. Here's what UBC was teaching medical students up until mid 2024 (when they removed 👉the explanation only👈 after I let them know how badly out of date they were).

The apprenticeship model cannot process science that conflicts with received wisdom from senior docs.
You laugh, but these people live in a totally different world already. Everything is memorized special cases and they just don't get the concept of mechanism at all. This is what UBC (in Henry-land) has been teaching its med students for years 👉in their PPE training👈 - no wonder they're clueless:

Some encouraging news from Japan, where their wave of "clade K" looks quite short and sharp. Note they did pre-emptively return to masking in healthcare settings, well before the wave peaked.

Thank you for this.

Stat News had a goofy puff piece quoting (of all the perennially wrong-about-Covid people!) Monica Gandhi, in support of Høeg's supposed epidemiology chops

Yes; thank you for seeing and acknowledging this common ground. These are the kind of situations where people should be maximally protected, including with N95s.

Swedish #LongCovid patient org have just taken the "department of health" to court, for among many things, refusing to take in global science, to trying to give health care the wrong (it is all in your head) idea about Covid.
Patients won on some counts. Hopefully for the better.

PPE (incl. respirator masks) was extremely effective at protecting healthcare workers in Korea in 2020-21):

"Among the 181 participants, only one developed SARS-CoV-2 antibodies... this infection was more likely acquired outside the hospital than during clinical duties."

And yes, there absolutely were people like this when there were calls to clean drinking water, develop safety standards for cars, remove asbestos, ban smoking, and every other public health measure ever.

I’m talking about peer reviewed research, not “social proof.”

How many hospitals required obstetricians to wash their hands before delivery in 1846?

Hygiene improvements have always encouraged fierce resistance.

Remember there is no reason for alarm. You can easily protect yourself with a well-fitted respirator. Back it up with air filtration and vaccination.

Thank you for masking!

Pre-Covid, there were both initiatives to reduce hospital-acquired infection to zero, and a lot of theoretical sympathy for sick children. These should still be the prevailing concerns in a children's hospital, even if people find respirator masks inconvenient.
