🇦🇹 Representative genomic surveillance of SARS-CoV-2 in Austria week 11, 2023 across most regions. Current analysis includes samples until March 9th allowing faithful nowcasting. A collaboration of #AGES @agesnews and @IMBA_Vienna/@oeaw.
1/6
With 2688 successfully sequenced samples this week Austria still has a remarkably good overview over the pandemic and become an international role model in surveillance.
2/6
Austria is past the XBB.1.5 peak and also EG.1 (a.k.a. XBB.1.9.2.1) will not mount another peak here. But we detected another two cases of XBB.1.16, which deserves close monitoring as only the latter, but not XBB.1.5, appears to result in growing incidences in India.
3/6
If you are curious, here is the regional analysis of our sequencing pipeline:

And here a more fine-grained analysis on the individual mutations over the last weeks:
5/6
So the current wave, by sewage signal similar to the first Omicron waves, is slowing down. Given the regularity of this, the next one is up in summer if XBB.1.16 does not surprise us before.
Have a good weekend!

Today the intergovernmental panel on climate change is gathering. “The evidence has been clear, convincing and irrefutable. (…) We are at the tip of a tipping point.” Says Antonio Guterres, Secretary General of the United Nations, March 13th 2023

… But the Austrian chancellor just called it “Doomsday Madness” and points out that some “excellent authors” proof it to be a essentially a hoax.

After his frontal attack of science in context of the national covid-response essentially blaming lockdowns on the consulting experts just a few weeks back, this is the next incidence showing a deep ignorance and mistrust towards science.

🇦🇹 Representative genomic surveillance of SARS-CoV-2 in Austria week 10, 2023 across most regions. Current analysis includes samples until March 3rd allowing faithful nowcasting. A collaboration of #AGES @agesnews and @IMBA_Vienna/@oeaw.

Based on reported case numbers at least, XBB.1.5 appears to have passed it’s peak. This trend is less obvious but also seen in wastewater, see page 10 in the link below:

2/4 Image
Extrapolated absolute case numbers also illustrate the reduced growth. Truly a good sign if the trend holds! Other countries are presumably a bit behind with XBB.1.5, so important to see the trend changing. In Austria relative share of XBB.1.5 is at ~69% currently.

🇦🇹 Representative genomic surveillance of SARS-CoV-2 in Austria week 8, 2023 across all regions. Current analysis includes samples until February 15th allowing faithful nowcasting. A collaboration of #AGES @agesnews and @IMBA_Vienna/@oeaw.
1/4 Image
XBB.1.5 continues to grow and makes up ~60% of cases now in nowcasting. Shown here are the relative fractions within the total reported (!) cases.
2/4 Image
In quantitative sewage monitoring the situation looks very different. The level of detected SARS-CoV-2 appears to be near the values of last year at this time. Infection risk is thus very high currently and hospitalizations are also increasing.

🇦🇹 Representative genomic surveillance of SARS-CoV-2 in Austria week 7, 2023 across all regions. Current analysis includes samples until February 8th allowing faithful nowcasting, sample numbers dropping though. A collaboration of #AGES @agesnews and @IMBA_Vienna/@oeaw.
1/6
Current significant growth in incidence is almost exclusively due to XBB.1.5, that reached >50% of cases now.
2/6
Only very few other lineages continue to show growth in absolute numbers as visualized when extrapolating shares of lineages to absolute reported numbers.

Eine Initiative, das gesellschaftliche Corona-Trauma aufzuarbeiten, wie Kanzler Nehammer anregt, wäre ja prinzipiell sehr begrüßenswert.
Zuerst sollten wir aber diskutieren, daß das Virus jeden einzelnen und uns gemeinsam an die Grenzen gebracht hat.

Deshalb sollten die individuellen und gemeinsamen Be- und Überlastungen verarbeitet werden. Wer wurde wann warum über die Maßen belastet? Auch wer hat wann wo ungerecht profitiert?

Aber nochmals: Die Ängste, die Belastungen, das Leid, das die Pandemie verursacht hat, ist vor allem eine Naturkatastrophe und nicht die Schuld von irgendjemand. Gegenseitige Schuldzuweisungen machen es nicht viel besser.

🇦🇹 Representative genomic surveillance of SARS-CoV-2 in Austria week 2, 2023 across all regions. Current analysis includes samples until January 5th allowing faithful nowcasting. A collaboration of #AGES @agesnews and @IMBA_Vienna/@oeaw.

The variant situation for Austria changed dramatically between the years. While we had a swarm of lineages growing in numbers until Christmas, it is now just one lineage showing growth: XBB.1.5.
2/5
XBB.1.5 is a descendent of the strongly immune evasive recombinant XBB that now acquired a mutation improving binding to the ACE2 receptor on human cells and thereby infectivity. It is observed across Austria now. Nowcasting predicts it to be currently at ~8%.
