A lot of questions to my recent tweet on South Korea ask how did they do so well?

Its a combination of great talent & leadership, uniform non-politicized messaging, border control, effective test/trace system, high compliance with masks, distancing, & vaccination.

A strategy.
Many replies I got say it best. And I'll highlight some of them.
Test and trace early on combined with border control established a system that has been sustained for 2 years.
Acting fast with targeted measures.
People followed the rules. If every single person wears a mask, it's like you are wearing two masks. Doubles the protection.

If everyone is vaccinated, then you reduce your risk.
IT support
More on using technology to help with public health. High efficiency.
And this from an older thread. They did it without lockdowns. It's a democracy.
Best of all.

Omicron who?

South Korea continues to be the role model. I hope they can sustain their science driven strategy which so far has saved hundreds of thousands of lives.
It's Korean American Day. 👏🎉
Even if Omicron causes a problem in South Korea, they have already won. At this point 93% of adults are fully vaccinated. Over 40% have been boosted. So their deaths and hospitalizations will stay much lower than here.

If you act like everyone is going to get omicron anyway, you will get omicron.

If you take precautions & try your best not to get omicron, you may not get it.

If we take precautions, we can also delay infections. We prevent hospitals from being so totally overwhelmed.
Hospitals getting overwhelmed means it's harder to provide care for all other illnesses as well. @Craig_A_Spencer google.com/amp/s/amp.cnn.…

It's a good day to remind people that the "Great" Barrington Declaration actually said this.... and that too in Oct 2020 when we didn't have vaccines.

We know what happened since to places that followed this philosophy. Image
Yes. I did say this was a terrible idea then. It was reckless in my opinion.
"Society as a whole enjoys the protection..."

Right. We had 10 million cases then in the US. 60 million now.
225,000 deaths then, over 825,000 deaths now. So much for "protection offered to the vulnerable by those who have built up herd immunity".

From a low of 70,000 to over 700,000 cases a day in less than 2 months.

A >10 fold increase in daily new cases in the US. #Omicron @OurWorldInData
If you had told me in October that we would have >700,000 cases a day in Jan, I would have categorically said, no way.

Covid continues to humbles us.
Unfortunately as a result of this dramatic increase, we are facing a crisis in hospitals across the country.
Vaccines are greatly reducing risk of hospitalizations, ICU admissions, and deaths during Omicron wave. Please get vaccinated and boosted.

In the US: 3 doses minimum ages 12 and older. And 4 doses for immunocompromised.

Looks like communication is a problem area for health care agencies. So I have made a list of talking points for them.

1. Omicron is a serious threat because it is highly transmissible, more than any previous variant, and too many people will get it too fast.
2. Omicron appears "mild" mainly because a lot of people have some prior immunity from prior Covid or vaccines or both. But it is quite capable of severe disease. Don't be complacent.
3. There are some who are particularly vulnerable to omicron:

a) Unvaccinated and inadequtely vaccinated. Unvaccinated includes those for whom vaccines not available to them (eg., young children; people in low income countries)

b) those with compromised immune system

In one month since this comment, US COVID cases have increased 4 fold.

From 120,000 per day to 600,000. Hospitals are overwhelmed with patients and staff shortages. Care for other illnesses affected. @DrEricDing Image
The next month is going to be very difficult everyone.

We are lucky that vaccines were developed in time. They have helped reduce severity.

We are unlucky in that 40% of the country is not yet fully vaccinated. And 80% have not yet received the booster dose.
Cases occurring so incredibly fast in such a short time leads to 2 problems.
1) even if proportion who need hospitals is small, it is big in absolute terms: overwhelms hospitals.
2) staff shortages due to illness or quarantine causes problems for care for all other illnesses.
