Stop making fun of older kids who still believe in Santa Claus, there are ID docs who still believe in droplet transmission.
If you think I am being harsh, there is no such thing as pure droplet transmission. This is simply physics. Even a purely upper respiratory tract infection produces infectious aerosols as well as droplets. Lower respiratory infections are all aerosol transmission.
Your loose surgical mask will catch droplets. But aerosols will go around the gaps. You need to close the gap by wearing well-fitting medical-grade masks. #N95sForAll

As a pediatrician, reports like this scare the hell out of me.

What they are describing is not just sensory dysfunction, but brainstem dysfunction.

publications.aap.org/pediatrics/art…
This is actually what I study in my sleep apnea research. A brainstem center called the Kölliker-Fuse matures during early life, programming coordination of the swallow.

Case #1 The 16 month-old child can chew food, but cannot swallow what she chews. She can only swallow liquids
She is also not speaking the single word that she could say prior to getting sick. She was infected at 12 months of age, a time of critical developments for eating and speaking.

The Kölliker-Fuse is also involved in speech and breathing coordination.

Our public health leadership failed us.

And I am sure not a single one will face consequences for the disaster that they not only allowed to happen, but facilitated.
They refused to listen to aerosol scientists who had collected the data over the past two decades that respiratory diseases are spread predominantly by respiratory aerosols.

And two years into this disaster, they still don’t provide the people with the tools needed to fix this.
We all need to understand aerosol transmission.

We all need to wear tight fitting, effective masks indoors or at close quarters.

We need to clean our indoor air through ventilation and air filtration.

We need to monitor ventilation with CO2 detectors in public spaces.

If you want to live, get vaccinated.

If you want to avoid getting infected, passing it on to another person, and risking Long Covid, wear a properly fitting N95 mask or better, and ventilate and filter the air.

The vaccine is a life insurance policy.
I have gotten complaints about my tweets because they are too negative. Tough.

I believe in the truth. People deserve the unflinching truth. Only truth allows you to make the best decisions.

Lying to people is disrespectful and wrong. And it will always ultimately backfire.
I see vaccinated people all around me catching Covid. I have been exposed myself as a result. Don’t tell me that vaccines protect against infection now. They do not. But it’s the best life insurance policy around, other people than living in a responsible country like Taiwan.

Who is Mark E Lindsay, and why did he block me?
I don’t know who he is, and I have no recollection ever interacting with him.
Only clue I can come up with. @alisadoc1

Amazing that two years into this, people still don’t understand that it starts out mild and then worsens

Given omicron’s doubling time, the denominator you have to work with for outcomes is the number of cases that were infected at the same time as the cases you are measuring.
So to determine case hospitalization rate, you have to use the number of cases from when hospitalized people got sick, some 6-8 days ago. Not today’s case number.

Same with case fatality rate — you have to go even further back in time.
So if we have people dying from Omicron now, when case numbers were barely detectable 10 days ago, we should be very, very afraid.

Ohio is calling in the National Guard to help out in the hospitals.
The state government is also paying for temporary staffing in hospitals.

Would be easier and cheaper to mandate masks, TBH.
DeWine is thanking health care workers. I wonder if he will order pizza.
