Spread of the #SARSCoV2 #Omicron variant sub-lineage BQ.1 in the EU/EEA.

BQ.1, including its sub-lineages, has been designated as Variant of Interest (#VOI) by ECDC as of 20 October 2022.

Full report: bit.ly/3VMLay0 Image
Based on modelling estimates, it is expected that by mid-November to beginning of December 2022, more than 50% of #SARSCoV2 infections will be due to BQ.1/BQ.1.1.

That level is expected to rise by the beginning of 2023, to more than 80%.

The observed increase in the growth rate of BQ.1 is probably driven mainly by immune escape.

This variant and its sub-lineages will probably contribute to a further increase in cases of #COVID19 in the EU/EEA in the coming weeks and months.

La #variante"Nu" B.1.1.529: segue un thread con le poche info che abbiamo. Ma non c'è da andare nel panico, ve lo spiego. Iniziamo. 1/21
#COVID19
Le autorità sudafricane sono allarmate per la rapida diffusione di una nuova #variante che in tre settimane è passata dall'1 al 30% di casi, soppiantando la #Delta (attualmente predominante nel mondo). Vediamo di cosa si tratta. 2/21
Si tratta di una variante di #SARSCoV2 emersa per la prima volta l’11 novembre 2021 a seguito di tre rilevamenti in #Botswana. 3/21

Muita gente ficou surpresa com as notícias referentes a C.1.2, uma variante possível aumento na transmissão e com algum escape imunológico anunciada pelo Inst. Nacional de Doenças Transmissíveis da 🇿🇦 e da Plataforma de Inov.e Seq. de Pesq. KwaZulu-Natal

Acompanha 🧶👇
RESUMO:
🔹Variante com características preocupantes, mas que não tem circulação global
🔹Nada nos diz que vacinas não abrangeriam ela
🔹Mais um indicativo de que o vírus está se adaptando
🔹A desigualdade de distr. de 💉 no 🌎 É UM PROBLEMÃO
🔹💉E 😷pelo amor de Deus

Detalhes👇
Não é segredo, nem novidade, que a permanência desse estado de transmissão elevado, que é construído por vários fatores, (baixa cobertura 💉, falta de adesão adequada a medidas como uso de 😷, p.ex), gera um risco de vermos novas variantes surgirem

#拡散希望 当ラボ主宰の新型コロナ研究コンソーシアムG2P-Japanのプレプリント第3弾を、bioRxiv @biorxivpreprint に公開しました。本研究では、「注目すべき変異株 #VOI 」のひとつであり、南米で流行拡大する #ラムダ株 のウイルス学的特徴と進化動態を描出しました。1/5
biorxiv.org/content/10.110…
まず、#ラムダ株 が、ワクチンで誘導された #中和抗体 に強い抵抗性を示すことを明らかにしました。次に、ラムダ株特有の、スパイクタンパク質の大きな欠損変異(246-253欠損変異)が、このラムダ株の中和抗体抵抗性を規定していることを明らかにしました。2/5
分子系統学解析の結果、「246-253欠損変異」を持つ #ラムダ株 は、昨年7月頃に誕生し、その後南米各国で流行拡大したことが示唆されました。さらに、#ラムダ株 特有の #L452Q 変異が、#デルタ株#L452R 変異と同様に、ウイルスの感染力を増強させることを明らかにしました。3/5

1/5 Aktualisierter #RKI-Bericht zu den #Virusvarianten (Variants of Concern #VOC, Variants of Interest #VOI) von #SARS_CoV_2:
➡️rki.de/DE/Content/Inf…

Die Darstellung basiert auf Daten aus der #Gesamtgenomsequenzierung.
2/5 Der Anteil der VOC B.1.617.2 (#Delta) nimmt weiterhin stark zu & hat sich wiederum innerhalb einer Woche verdoppelt. Diese starke Zunahme des Anteils der #Variante B.1.617.2 geht mit einer leichten Zunahme der Delta-Fallzahlen bei weiterhin abnehmender Gesamt-Inzidenz einher.
3/5 Die aktuell vorliegenden Daten zeigen, dass die #VOC Delta sich gegenüber den anderen Varianten, insbesondere auch gegenüber der bisher dominierenden Variante B.1.1.7 (#Alpha), durchsetzen wird.

1/4 Der #RKI-Bericht zu den besorgniserregenden Virusvarianten (Variants of Concern, #VOC) von #SARS_CoV_2 wurde aktualisiert:
➡️rki.de/DE/Content/Inf…

Daten KW6-KW12 zeigen Analysen der Erhebung des Laborverbundes, Daten ab KW15 aus der Gesamtgenomsequenzierung (KW16).
2/4 Die #VOC B.1.1.7 ist weiterhin die dominierende #SARS_CoV_2-Variante in Deutschland. Aktuell ist keine Abschwächung des hohen Anteils von B.1.1.7 zu beobachten. #B117
3/4 Neben den besorgniserregenden Varianten #VOC, gibt es einige unter Beobachtung stehende sogenannte Variants of Interest #VOI. Die VOI haben gemein, dass sie Mutationen aufweisen, die mit erhöhter Übertragbarkeit oder reduzierter Antikörperneutralisation assoziiert werden.

Logik zum #Öffnungsplan der #Bundesregierung
Wo, wie und wie schnell infiziert man sich mit dem #Coronavirus? Solange die Regierung Entscheidungen - magels Datenlage - ohne Evidenz trifft, solange ist es Willkür, wann welche Bereiche geöffnet und andere geschlossen bleiben #Spahn
Die Mutante #B117 erreicht in diesen Tagen -in den ersten Bundesländern- ihre #Dominanz. #R steigt zeitgleich und die #Regierung erhöht per #Öffnungsplan die #Mobilität: B117, Öffnungsplan u. gesteigerte Mobilität sind drei Faktoren die logisch #R exponentiell beeinflussen können
Zeitgleich werden #Kitas u. #Schulen geöffnet, also die Versammlungsorte, vor deren Öffnung uns Experten und Ärzte aus #Israel u. Kanada warnen. Begründet wird die #Öffnung mit "Meinungen" von Wissenschaftlern, deren #Studien -manipulierte Daten- aus #Schweden zitieren #twlz #KMK

Meanwhile in #France,
"the peak of this second wave is over"

(according to the President in his Adress to the Nation):
Wait... "the peak is over" doesn´t mean "it´s back to normal"!

Confinement will only fall on December 15,
if there´s less than 5.000 new cases a day.
(today it´s ~9.000).

France is disappointed.🙁

Although they certainly can make it happen.
Meanwhile in #Switzerland:
(excess mortality of the second wave is significant)

Good news: fastest decrease in infections happens in the worst hit areas now.

As #COVID19 cases are found to spread, #Melbourne (city of ~5 million) tries to contain them by going into #Lockdown.
(The interview features the idea of a dedicated #Quarantine building - that would actually help, I guess)...
"People acting as if the pandemic was over was 'not the answer, it is part of the problem' ".

"The virus had leaked from postcodes already under the stay-at-home orders to other parts of #Melbourne."
(and beyond, it is feared).
Due to #Melbourne's outbreak, neighbouring South Australia is about to completely close it's borders to #Victoria.

(Nearly) no exceptions. And those essential few who are allowed in, will have to wear facemasks the entire time...
