It seems like everyone is coming down with #covid19 right now.

It's NOT a scarlet letter.
But you DO need to know your risk, and what to do.

So here's an honest thread (with receipts!) on what this means for you. 🧵
1⃣ How at risk are you of catching the virus?

Approximately 2/3 of people who live with someone diagnosed with #Omicron, get infected - assuming no vaccines & no isolation.

cdc.gov/mmwr/volumes/7…
The vaccine + booster reduces that risk by 30-50% -

So you're probably looking at ~30% risk of infection (maybe lower, if your infected household member isolates & masks)!

It's a funny thing: we're literally all at risk... but also, #VaccinesWork

📣 THREAD: Earlier today @PaulKrugman linked to a post of mine from December which showed how the #DeltaVariant ravaged Red America for 6 months. 1/
acasignups.net/22/02/01/reque…
In the post, I noted that in June 2021, the COVID death rate in the reddest decile of the U.S. was "only" 43% higher than in the bluest decile, but by August it was running an astonishing 7.3x higher in the reddest 10th of the country than the bluest 10th: 2/
For the full 6-month period (June - December), the death rate in the reddest decile averaged around 5.8x higher than in the bluest decile.

More recently I noted that the #OmicronVariant is a whole new chapter, with case rates running higher in *blue* counties than red ones... 3/

⚠️REINFECTION RISK—Omicron doesn’t protect from future infection much—2 studies “taken together, ➡️ our results suggest that #Omicron-induced immunity may not be sufficient to prevent infection from another, more pathogenic variant, should it emerge in the future” 👀 #COVID19
2) “immunity based on #Omicron infection is weak for (another) Omicron reinfection” ⚠️

Don’t risk #Omicron!!!
3) That said, #Deltavariant infection seemed to protect more. But Delta is risky too. So unless you had a severe infection of either (don’t risk it), your mild case of #Omicron isn’t a good guarantee of high protection. You may have some, but not a guarantee.

New research shows that only 10% #Omicron cases are in ppl who have gotten #COVID19 #Booster.

This may be MISINTERPRETED as:

"Only 10% of people w/ #BoosterDose get #OmicronVariant"

OR

#BoosterShots are 90% effective"

Not that simple! READ ON!

First, this is NOT a critique of the study (currently a pre-print).

Researchers at @MethodistHosp who did this provided a VERY valuable piece of info and are not making any inappropriate claims. Great work!

It's just that it's easy for public/media to misinterpret results!
3/

Paper reports on a total of 1313 #OmicronVariant cases in the Houston, TX area.

See table below:
~49% of cases in those not vaccinated (0 or 1 does)
~51% are #BREAKTHROUGHS.

Of those #Breakthrough cases,

535 cases w/ 2 #vaccine doses
140 cases w/ 3 doses (i.e., booster) Image

Let's compare NYC & Hong Kong #COVID19 experiences.

NYC population = 8.4 million; HK = 7.5M.
NYC is averaging >40K cases/day, totaling nearly 2M since Jan2020, with 35,883 deaths.
HK has had zero-to-7 daily COVID cases over last 8 mos, 12K since Jan2020 w/200 deaths.

2/ What's the difference?

HK has strict border controls, testing, tracing and mandatory quarantines in hotels & detention centers, under observation, with jail for violators.
NYC, like rest of USA, has near-nil track/trace/test/quarantine in use. NY "control" - persuasion.

3/ Of course, China shut the border with HK, sealing the City off from Mainland. And over last 2 yrs PRC has imposed a police state on HK. People have no choice but to obey mask, vaccine, quarantine laws.
But, most vaccination is with lousy Sinopharm & Sinovac which offer...

I have been tweeting about endemicity for a while now but I'll explain it here for anyone who wants to better understand how this pandemic will end from an immunologist's POW:
This pandemic won't end by us eradicating #SARS_CoV_2 there are three main reasons for this:
1) This virus has animal reservoirs meaning it can jump back and forth between humans and other hosts. So forget about we will eradicate this virus or COVIDzero
2) Although our vaccines are very effective against severe #COVID19 they don't confer sterilizing immunity meaning...
...you can be immunized and still get infected and transmit the virus.
3) Even if we had vaccines that conferred sterilizing immunity, we couldn't possibly vaccinate the entire human population to prevent the emergence of VOCs that can evade immunity...

nu de scholen 🏫weer open gaan is het belangrijk om te weten welke klachten "typisch #omicron" zijn

de Engelse #omicron-symptomen top 5⃣ =
loopneus, hoofdpijn, moeheid, niezen en keelpijn

bmj.com/content/375/bm…
in Zuid Afrika 🇿🇦 stond #moeheid ook voorop, samen met een 'ruwe keel' (scratchy throat), #hoofdpijn en lichaamspijn.

en bijna geen: geur-smaakverlies of hoesten!

news.sky.com/story/omicron-…
áls we willen dat mensen met #omicron zich laten testen (GGD of #zelftest), dan moeten deze symptomen ook genoemd worden als testindicatie: #hoofdpijn, ruwe keel, (opvallende) #moeheid

ook voor kinderen, waar #Covid19 zich soms atypisch presenteert (hier thuis: vooral hoofdpijn)

⚠️Totally “mild”—US pediatric #COVID19 hospitalizations nearly 2x last year’s all-time high. Kids shouldn’t be hospitalized—kids shouldn’t be getting #LongCovid. Kids have their whole lives ahead of them. Let’s protect the kids. 🙏

HT @DrWilliamKuHealthData.gov
2) What a sad way for kids to spend Xmas vacation—moreover these infected kids will go back to school next week and infect more kids - tragic. ➡️ The worst pediatric COVID hospitalization state isn’t Florida — #1 is Texas.

Figure by @DrWilliamKu
3) Florida is just behind Texas in pediatric COVID hospitalizations— Florida may soon overtake its summer #DeltaVariant peak at this rate.

FLORIDA—Surpassing all-time #COVID19 high with hospitalizations surging like clockwork behind the case rise. Some claimed Florida was as “herd” and #Omicon protected because of recent July-September #DeltaVariant wave. This looks unlikely.

Figure by @DrWilliamKu
2) if even England is already exceeding hospitalization forecasts, will Florida do any better? Doubtful. 👇
3) Will Floridians follow the CDC to the T? Or even take enough precautions in face of already muddy CDC guidelines like this??

Mon cadeau de Noël à vous twittos :
j'ai évalué la létalité de #Omicron en réalisant une estimation de la vague #Omicron complète. Avec les chiffres disponibles aujourd'hui (JHU), on peut estimer que #Omicron serait 5x moins létal que #DeltaVariant
@MartinBlachier votre avis ?
Certes il est encore tôt pour accorder une très grande confiance à ces chiffres, difficiles à comparer par ailleurs entre pays car les politiques de tests, le comportement et l'état de santé des populations est différent. Mais c'est quand même à priori plutôt assez rassurant.
Il faudra certainement réactualiser cette analyse pour améliorer la confiance dans ces chiffres. Si le rapport de létalité relative entre delta et omicron était vérifié, cela voudrait probablement dire que #omicron est proche de la grippe saisonnière (0,1%).

🧵 Your risk of dying if you get #Omicron in the next few wks as opposed to a few months from now will be dramatically different. We are facing huge surges in Jan that will make it hard to get seen in an ER in a timely fashion & even harder to get admitted to a hospital.
2/ Should you be fortunate enough to find a bed, you will have drs & nurses overwhelmed with patient volume, who will have very limited time to spend w/ you. Dr to patient (& nurse to patient) ratios will be unsafe, like unthinkable in pre-#pandemic times. #Omicron #MedTwitter
3/ This alone will dramatically increase your odds of death. That’s been seen in the prior surges. With #Omicron, the # falling ill at once is 🚀 off the charts. I’m seeing attack rates of 75-100% even in fully #vaccinated (& some #boosted) gatherings & households. #MedTwitter

Let’s talk about the social function of #COVID19 vaccines, and how that is likely very different for working people vs. the professional class.
🧵1/17
We’re hearing a lot now from pundits and govt leaders that “the vaccines were never intended to stop infections, their purpose is to prevent hospitalizations and deaths”

Setting aside the revisionist history, what are the implications for workers vs white collar folks?
2/17
PAID SICK LEAVE:

Most white collar professionals have it, most workers don’t.

College-educated folks can often work from home during quarantine or isolation.

Blue collar, service, retail sales workers can *never* work from home. Never.

I know personally 3 people receiving monoclonal antibodies this evening. All have had 3 doses of #COVID19 #vaccine or prior infection + 2 doses of vaccine. All are careful. They all have risk factors, but all are pretty symptomatic. Jan is gonna be…rough. #MaskUp. #Omicron
Tweet 2: A lot of people seem to be panicking based on this anecdote. Panic is NOT productive. Instead you need to calmly plan & act to reduce your risk. These are some effective things you can do right now:
👉Upgrade your masks. No more cloth alone. Best is N95/KN95/KF94...
Tweet 3: As an alternative to N95/KN95/KF94, if you can't tolerate those or don't have them, I rec a surgical mask (ASTM level 3, 3-ply is great) w/ cloth mask over it. Read this: scientificamerican.com/article/why-we…. The non-profit @projectn95 has vetted, affordable PPE including masks.

The GOP started lying about COVID when Trump called it a "hoax". THAT lie has cost hundreds of thousands of American🇺🇲 lives. It also made them and their friends billions $$.

2/ Trump said it was a hoax on Feb 27, 2020. Community transmission was being confirmed in multiple cities in the US. Around the world, case numbers were increasing exponentially everywhere one was found, and economic disruptions began roiling global financial markets.

⚠️FASTER HOSPITALIZATION WITH #Omicron—Latest data on hospital admissions in London (🇬🇧Omicron epicenter) shows Omicron wave is sending patients to hospitals sooner in 6 days than versus Delta (9-10 days). And the model suggests similar severity, not “milder”.🧵

Data via @OYCar ImageImageImage
2) Let’s look at the other 10 day model for new #Omicron — it seems it’s a poor fit to the actual hospitalization data. It’s visible on both the log scale and natural scale that it’s not a good fit. ImageImage
3) Now let’s for a moment test whether #Omicron is “milder” - half as severe as Delta, but just sent people to hospital faster, but not as often. Does it fit the data well? Not exactly… the latest few days doesn’t jive with that “milder” model. Image

BREAKING—Largest study of 2-shot Pfizer vaccine effectiveness against #Omicron from largest health insurer in 🇿🇦:

📌33% VE against #Omicron (symptomatic?) infection

📌70% VE against #Omicron hospitalization (93% against #DeltaVariant before in 🇿🇦)

➡️Urgently need boosters.🧵
2) the new study also mentions 20% greater risk of hospitalization among kids with #Omicron compared to an older strain last year.
3) Also, the protective effects of prior infection has waned and further erode by #Omicron. ➡️ Bottomline: don’t rely on past infection immunity!

Doctors & nurses in UK 🇬🇧 are too traumatized and refusing to be redeployed to #COVID19 hospital wards with the looming #Omicron surge approaching. If & when the hospitalizations rise… I pray everyone listening is #vaccinated & #boosted, or else the 🏥 may not have enough beds.
2) it’s not a matter of “if” hospitalizations for #Omicron will rise, it’s a matter of “when” and how much…
3) don’t forget, it’s the more contagious transmission of a virus that will ultimately kill more people than the individual severity of a virus. The hospitalizations will inevitably go up, albeit slower at first if mild (not proven yet), but catch up with a vengeance later. 👇

1/ #Omicron 🧵

Been a few weeks since we heard of #OmicronVariant

Thought I would look at what we have learned so far, and some questions that remain, using @OurWorldInData & some global reports.

So at peak, South Africa has had ~400% increase in cases.

#COVID19BC
#cdnpoli
2/ #Omicron - South Africa

Can we attribute the rise of cases directly to Omicron?

Looks like the answer is yes.

South Africa cases are 100% Omicron now.
Botswana ~20%.
Canada/UK/USA still low, but increasing.

(Other countries where it has been found for comparison)
3/ #Omicron - What's happening with Delta?

This seems obvious, but just to confirm with the sharp increase in Omicron, there is a concurrent steep decline of #DeltaVariant as it is displaced.

This makes us all tense as we still have a lot to learn, but it's not all doom & gloom

💡[Whisper]… there is actually a proven vaccine for kids age 2-4 that is *CURRENTLY UNDER REVIEW* at the @US_FDA with an EUA app submitted on November 5th—but FDA has not moved yet on approval meeting. ➡️Why is the media not talking about this? #COVAXIN ir.ocugen.com/news-releases/…
2) COVAXIN™ (BBV152) is a whole-virion, inactivated vaccine, manufactured using a Vero Cell manufacturing platform, as has been used in the production of the inactivated polio vaccine for the past 35 years, as well as of other traditional childhood vaccines.
3) The submission is based on results of a Phase 2/3 pediatric clinical trial conducted by Bharat Biotech in India with 526 children 2-18 years of age, which bridged immunogenicity data to a large, Phase 3 safety and efficacy clinical trial in nearly 25,800 adults in India.
