„Der technische Unterausschuss der WHO für die Auswahl von Impfstämmen hat sich letzte Woche auf eine Empfehlung geeinigt, den ursprünglichen #SARSCoV2-Wildtyp-Stamm zu entfernen. Ich bin ziemlich sicher, dass diese Empfehlung den Weg zum VRBPAC finden wird.“

➡️ Unsere Ergebnisse deuten darauf hin, dass der Ahnenstamm im derzeitigen bivalenten #COVID19-Impfstoff die Ursache für eine tiefe immunologische Prägung ist. Seine Entfernung aus künftigen Impfstoffzusammensetzungen wird daher dringend empfohlen.…
➡️ Unsere Ergebnisse deuten darauf hin, dass die WT-Komponente bei der Aktualisierung der COVID-19-Impfstoffe für #XBB-Linien aufgegeben werden sollte, und dass Personen, die noch nicht mit -#Omicron in Kontakt gekommen sind, zwei aktualisierte

Someone on just asked me if I'd read the reports about how masks don't work. My answer:
"You mean the crackpot anti-mask 'theories' designed to dupe people into believing masks don't work so we could get to this point in history when the World Health Organisation 1/
(WHO) openly collaborates with the profiteers of the Capitalist system to officially declare a Level 3 biohazard pandemic over at the expense of millions more future deaths and the crippling of people's (including children) health for the rest of their lives? 2/
Yes, I've read them. After I finished reading them I put them where they belong - in the blazing fire of humanity's fury." 3/3

China has brought back testing centers as well: all around Asia (ie those closest to India, the home of #XBB116 #SARS3 #Arcturus #COVID19 we see increasing signs to control the virus: they are only a few weeks ahead of us in terms of spreads and are currently being hammered
I get serious Jan 2020 vibes from all this:
Despite the fact we see so many countries taking some form of action in Asia, with the Indian PM himself decalring that 'covid is far from over' months ago now and announcing a 5 point strategy to tackle the new strain: I see nothing in the west at all

#Arcturus is already in the UK at lower levels. We can all play our part to prevent a bigger wave. #WearAMask #N95 Open windows. Please watch this video from WHO ‘hundreds of millions’ of people will need long term care. Why isn’t this on the news @BBCNews the Public need to know
Risk increases with each reinfection as you can see from the graph below. The more times you catch COVID the greater your risk.

BREAKING🔔 The 19th paper from G2P-Japan🇯🇵 is out at Lancet Infectious Diseases @TheLancetInfDis . We elucidated the virological characteristics of new SARS-CoV-2 variant of interest, XBB.1.16 (aka #Arcturus) Please RT🔥 1/…
XBB.1.16 = XBB.1 + #F486P, #E180V, and #T478K in spike.
cf. XBB.1.5 = XBB.1 + #F486P in spike (i.e., XBB.1.16 = XBB.1.5 + #E180V and #T478K in spike). 2/ Image
A phylogenetic tree shows that XBB.1.16 is a descendant of XBB.1, not of XBB.1.5. 3/ Image

#SARS3 #Covid #XBB116 #Arcturus is currently at just under 2% of cases based on sampling, so we're really at the start of this thing in the UK: Image
Breaking the UK up by nation we see the areas are all roughly the same prevalence: with Wales having the least Image
However, perhaps somewhat unexpectedly according to the data, US is well ahead of the UK, WITH A 5X increase in prevelence of nearly 10% of cases currently: that's very strange and somehwat makes me very much question the UK's data on this Image

NEW Study from the hard-hit Maharashtra area of India shows BRUTAL: #SARS3 #Covid #XBB116 #Arcturus strain has a fatality rate of 1 in 40 with a staggering 1 in 3 needing oxygen, and nearly 30% being hospitalised with the new strain: Image
Finally we have something resembling some form of actual data from India about this strain: and it's not pretty:

'Among the XBB.1.16* cases, 91.7% were vaccinated with at least one dose of vaccine against COVID-19. While 74.3% of XBB.1.16* ...
..cases were home-isolated; 25.7% needed hospitalization/institutional quarantine, of these, 33.8% needed oxygen therapy. Out of 276 XBB.1.16* cases, seven (2.5%) cases succumbed to the disease.'…

WATCH: explained here is how the new breakthrough PL-M drug works against any strain of the virus and that means it's going to work on the new #SARS3 #arcturus #xbb116 India strain that is frankly shaping up to be BRUTAL:

Galectin inhibitors are a brand new type of antiviral: they work by attaching to the galectin fold of the virus: a part of the virus which will not mutate unlike the spike, which is endlessly mutating, and the target of the vaccines: Image

Some more info on XBB.2.3. Aka #Acrux

➡️ XBB.2.3 has 4 defining mutations:

-Spike mutations: S:D253G & S:P521S
-ORF mutations: ORF1a:G2091S & ORF7a:A13V
-Beyond XBB.2, #Acrux XBB.2.3 has the Spike P521S & S486P mutations 1/

H/T: @T_Brautigan
➡️ Acrux XBB.2.3 was first spotted in India (Karnataka) & then in the USA—origin is somewhat unclear.

Here is the animated map by @Mike_Honey_ showing the spread of the XBB.2.3.* "Acrux" variant around the world. 2/

➡️ Singapore (26%) and India (22%) are still the hotspots.

Spain (11%) and Australia (8%) are also showing recent growth.

Spotted in many other countries including Japan, South Korea, China, the UK & the US. 3/ Image

Airport sequences constitute ~12.4% of sequences with sample collection dates in the last 15 days (#15DayTrends)

Its going to be a three way race to outcompete XBB.1.5*: XBB.1.9* vs XBB.1.16* vs XBB.2.3*

As of now, XBB.1.16* family looks to over take everything else!

As the new Indian #SARS3 #Arcturus #XBB116 strain takes off across the world, more and more are reporting horrific Covid eyes:

Studies show that Covid eyes contain infectious virus capable of infecting others: the eyes, do indeed, have it:… Image
'We found that ocular fluids from SARS-CoV-2–infected patients may contain infectious virus, and hence may be a potential source of infection'…
Interestingly, the CT value of the infected shows a lower (and therefore more infectious) value on day 13 than from the nose itself:

Further, on day 27 after seeming to go up and become less infectious,they then go back down implying they are more infectious.. Image

WARNING ABOUT #XBB116 #SARS3 #Arcturus COVID EYES FROM TIKTOKER WHO ENDED UP HAVING 'bleeding eyes' which Drs had to 'rip out of my face' after 'mild' cold-like symptoms to begin with...

h/t @AprilDalaman… Image
His horrific story is explained here: it all started with a 'severe cold' 3 weeks ago: which apparently resolved after a week...however, virus had already spread to the eyes and infected them: Image
It just got worse and worse and to the point where his eyes were swollen shut as the virus continued to replicate in the eyes: which contain high levels of ACE2 receptors that the virus uses to attach and replicate in: Image

It's likely that you'll be hearing more about another XBB descendant lineage, XBB.2.3*, alongside XBB.1.5 (Kraken), XBB.1.9.1 (Hyperion), and XBB.1.16 (Arcturus).

To aid communication, we're nicknaming XBB.2.3* "Acrux" (after the star
This is in keeping with the new nicknaming system that uses astronomical names and includes information about the lineage (starts with A-H = BA.2 lineage) and recombinant ancestry (has an R in the name = recombinant descendant).…
It's easy to track variant info thanks to amazing tools by folks like @Mike_Honey_, @RajlabN, and @nextstrain.…

🎉 Update!🎉

23B (XBB.1.16) is now available on CoVariants! It's visible as part of Per Country & Per Variant plots, on the shared mutation page - and of course, has a page of its own.


#XBB116 #23B #Arcturus
📷 Image
This is in line with the recent addition of 23B (XBB.1.16) as a @nextstrain clade - read more on that below 👇🏻!


As I covered earlier, 23B (XBB.1.16) is descended from the recombinant 22F (XBB) variant, with some additional mutations. You can read more about how it evolved & acquired those mutations below 👇🏻.

XBB.1.16 #Arcturus Covid surge in India: How it is affecting young children & infants.

Here are the key findings based on our study of 25 children from April 4-16’ 23:

1-Current outbreak is causing a mild febrile illness
2-Total duration of illness is only 1-3 days. 1/
3-Young infants are disproportionately more affected than older children.

4-The youngest infant was 13 day old neonate!

5-infants below one year had a significantly higher positivity rate than older children (40.38% versus 10.5%, p=000816). 2/ Image
6-Unlike the previous BA.2 Omicron wave, respiratory symptoms are predominating in young infants

7-Cycle threshold values for nucleocapsid and ORFlab genes on positive RT-PCR vary from 18 to 23. 3/
