When people without known vulnerabilities to COVID never mask, they force those who DO have known vulnerabilities to mask alone -- further compounding their vulnerabilities because it forces them to publicly REVEAL their vulnerability. Please help normalize masking.

Is it too early to encourage people to install ceiling fans everywhere? This is pretty cool. And it makes a lot of sense.
Ceiling fan🌸OBLITERATED CLOSE-CONTACT 🧑🤝🧑 RISK:
In eLetter in Science, we suggested CEILING FANS might cut short-range risk (w/ ventilation for long-range).
Singapore lab found just that (2023): mannequin underneath fan 5 ft from cough 🌬️ inhaled ~ 95% FEWER particles.

There's lots more you can do in addition to getting vaccinated. Mask, ventilate, filter, go outside/hybrid, test, and monitor. Those are just the basics. Please communicate more and better. I shouldn't have had to create this. You should have. Flier at .

Got an appointment with a new dentist I had vetted for separate patient rooms, HEPA filters, and N95 mask-wearing by the dentist. He just needed to check whether ONE of his four hygienists would be willing to wear an N95. Just heard back: NOPE. Go elsewhere.

I never understood how people who spent a lifetime fine-tuning their physical performance would be willing to risk a COVID infection -- particularly during one of the peak athletic moments of their lives. This was so easy to predict, and also not, apparently. Bizarro.

The movement of maskers, if it is to grow, will only grow by adding a lot of people who don't mask very much now. I try to reflect on that as I consider my public and private responses to various precaution protocols, new infections, etc.

People say their symptoms are getting better all the time, even if they aren't really. Symptoms can improve in the morning and then get bad at night, or vice versa. Symptom improvement seems to be a very poor metric to use when deciding when to return to work.

I don't have a child but have a suggestion: perhaps the child can carry and share readings from a CO2 monitor (i.e. Aranet4) with classmates. Then be sure to accompany that CO2 monitor with the sticker showing "rebreathed air %":

Your new guidance undermines the reputation of the CDC and your own career. You set the standard. Every time I called a dentist looking for COVID safety they repeatedly hid behind the assertion that “we’re following CDC guidelines.” Not safety, not common sense, just CDC.

I believe the endgame for COVID *might* emerge if we solve our contaminated air problem like we solved our contaminated water problem 100+ years ago with sewage systems. We need air filtration and ventilation and possibly far-UVC and other interventions to keep the air clean.
