📈SEWER SIGNALS—there is a sharp reversal in wastewater #SARSCoV2–many now rising across the US / plateauing and no longer falling, says CDC data. This parallels surge in Europe, just a few weeks behind. A #BA2 wave is coming—how soon/big is the question🧵 bloomberg.com/news/articles/…
2) it doesn’t require a rocket scientist to see there is a huge reversal in wastewater #SARSCoV2 showing more coronavirus surge— this progression will likely continue as #BA2 rises further in prevalence.
3) we already saw hints of it last week in pockets like Palo Alto and others. But this is becoming much more common in more pockets around the country.
4) As reminder, the #BA2 subvariant is now over 11.6% but quickly rising, and over 24% in New England. Also this data is over a week old. Likely even higher.
5) how much faster is #BA2? It has a 80-90% growth advantage per week versus BA1. This is why #BA2 is surging worldwide. BA2 is growing slowly in US because we recently survived a big BA1 wave but this is only a temporary barrier against growth. Waning will have effects too.
6) Why is it spreading? For some mutation related reason #Ba2 has higher attack rates than BA1. 25% higher secondary attack rate per case in households, and 30% higher among non households.
7) #BA2 data (red) from Denmark also shows MUCH MICH higher secondary attack rates over time than both #BA1 (old Omicron) and Delta variants. Honestly, BA2 needs to get its own Greek letter @WHO!! Don’t just call it a subtype of Omicron—it is just too different from BA1!
8) “But but but… it’s mild like the flu” some say…. Not quite, only if you’re *recently* boosted. Get at least that 3rd shot. With BA2, 2 shots just isn’t enough protection. 75% lower risk if 2 shots versus 95% lower risk of hospitalization boosted is a difference of 5x lower!!
9) ok, epidemiologist translation of where the 5x lower comes… if 1000 people, and there is 75% lower risk of hospitalization then 250 of 1000 will get hospitalized. If 95% lower, then only 50 hospitalized. 250 is 5x more than 50. But reality is 4x diff for some high risk folks.
10) As for #BA2’s infectiousness and evasiveness… apparently Shenzhen health officials made a surprising statement that BA2 seems to have a “high degree of concealment”. I’ve never seen such a descriptor before—unclear what it means yet but we should definitely be precautious!
11) Next wave already started in Europe. #BA2 is worse than BA1 already in many EU countries. Removing protections will cause deaths, sickness, disabilities of many more people. And no, not only “vulnerable” are at risk. Anyone who says BA2 won’t cause a surge are in delusion.
12) The UK 🇬🇧 also got hit hard by Omicron over December and January… they thought COVID was over… they thought wrong… not only cases surging in all age groups across all regions, but hospitalizations surging too. Especially in young kids!! 👇
13) I’m gonna go on a limb and says masks in schools kinda sorta maybe REALLY good idea right now to help protect kids and teachers from #COVID19 — 72% lower risk of infection for mandatory school masks versus partial.
And keep in mind, kids boosters not here yet—May or June.
2) And while officials say they do have enough vaccine doses available for immunocompromised people to get a fourth dose, if the rest of the population ends up needing an additional dose, they may not have the funds needed to meet the nation's needs.
3) The gap in funding would be particularly severe if a vaccine-evading variant comes along and a new formulation is needed. 👀
BREAKING—a bill to make Daylight Savings permanent just passed the US Senate by **Unanimous Consent** (S.623: Sunshine Protection Act, as amended to make Daylight Saving Time permanent). It only needs to now pass the House before going to Biden’s desk!
YES— it happened—the US Senate does something right today… permanent DST for the (hopeful) win!
To be clear— we are currently in “Daylight saving time” between mid March and November. So it would make our current time permanent. No more clock switching if it passes the House. en.wikipedia.org/wiki/Daylight_…
⚠️Kids hospitalizations ⬆️ 58%—I don’t know who needs to hear this—but endangering kids and letting 375 children 0-5 years hospitalized in last 7 days in England 🏴 is total insanity. 58% spike in 1 week! That’s #BA2 folks. #CovidIsNotOver
3) Europe already had a surge of old #Omicron… for those who think they are fully protected from #BA2 need to think again… and look how fast #BA2 driven when is moving.
Let this sink in—about half of elderly age 80+ in China are not fully vaccinated. And those who are are vaccinated with mostly SinoVac or Sinopharm—2 of the weaker protection vaccines. Half unvaccinated is gut punching bad—and bodes badly for the world if 🇨🇳 loses control.
2) And of the vaccinations in Hong Kong right now, most in the older generation are SinoVac and Sinopharm (non-mRNA) as well. Compare this to New Zealand or Singapore with very few Sino* vaccines.
3) while elderly 80+ are small, they have an outsized in place on total #COVID19 deaths in Hong Kong. The same problem will happen in China if it loses control in its population.
NEW—South Korea 🇰🇷 reports surging ⬆️ #BA2 subvariant now 31% of all cases as of last week. SK now has surpassed Hong Kong’s incidence peak, with hospitalizations & deaths also rising. 45% of all imported cases are #BA2 as well. 🇰🇷 is in trouble soon too. kdca.go.kr/contents.es?mi…
2) Yes, deaths in South Korea 🇰🇷 rising too albeit much much lower than Hong Kong.
3) reason is that South Korea is heavily vaccinated and heavily boosted—among the highest in the world. But that still doesn’t prevent hospitalizations and mortality rise because #Ba2 that efficient in finding unvaccinated and undervaccinated.
BREAKING—Lockdown just imposed for entire Jilin province, population 24 million. Jilin Province just reported 895 locally transmitted #COVID19 cases, & 131 asymptomatic carriers on Sunday, authorities announced Monday. Mayor of Jilin city has been fired.🧵 xinhuanet.com/english/202203…
2) This follows Shenzhen’s urgent lockdown yesterday. Shenzhen is the “Silicon Valley” tech and industrial epicenter of China. This likely has global implications if longer than a few days. All production is ceased during this time.
3) How serious is China about what is happening in Jilin? It has begun building a 6000-bed hospital isolation center… with work crews working 24 hours around the clock— scheduled completion is in 6 days from groundbreaking. Live camera of construction: weibo.com/l/wblive/m/sho…
