I sidste uge blev der målt den højeste konc. af corona i spildevand siden juni 2024 - dvs de sidste 15 mdr. (det tager 1 uge at analyse data)
Vi er kun i september- & vaccinationerne starter først i oktober- husk at udluftning, ventilation, HEPA-filtre- & masker mindsker smitten

Corona konc. i spildevand fortsætter med at vokse- hvilket er forventeligt når folk kommer hjem fra ferie, samfundet starter op igen & nye(re) varianter vokser op -& vi ikke minder om vigtigheden af udluftning, ventilation, HEPA filtre, bliv hjemme v. sygdom- & masker til sårbare

Corona koncentrationen i spildevand ser ud til at fortsætte sin stigning- det passer med mønstret fra tidligere år når sommerferien slutter & folk er tilbage på arbejdet & børnene i skole osv

Here's the latest variant picture for the "Global - Other" countries, to mid-July.

The NB.1.8.1 "Nimbus" variant remained dominant, but fell to finish at 49%.

XFG.* "Stratus" grew strongly to 36%.

Great work by Josette documenting the NB.1.8.1 vs XFG. Huge differences by country, likely reflecting different immune histories, namely, a longer history of infection in Europe, North America, & South-Central Asia (favoring XFG) than in East Asia, New Zealand, & Australia (favoring NB.1.8.1).
I have made an overview of the battle between XFG and NB.1.8.1 in the world

Samples collected on/after the 12th of May

NB.1.8.1 with a very high percentage in some SouthEast-Asian countries, and big in Oceania as well

XFG big in India/Pakistan/Bangladesh

Mixed in North America and Europe

Virological characteristics of the SARS-CoV-2 NB.1.8.1 variant
After the spread of SARS-CoV-2 JN.1, its subvariants, such as KP.3 (JN.1.11.1.3)1 and KP.3.1.1 (JN.1.11.1.3.1.1),2 and XEC (a recombinant lineage of two JN.1 subvariants),3 emerged and rapidly spread ...

Corona variant NB.1.8.1 ( aka Nimbus) er den nyeste variant der spreder sig - og vil sandsynligvis snart komme til Danmark (er her nok allerede).
“The infectivity of NB.1.8.1 was significantly higher (2·5-fold; p<0·0001) than that of LP.8.1. NB.1.8.1 binds more strongly to ACE2 than LP.8.1.5 … the increased fitness of NB.1.8.1 is due to its augmented infectivity rather than its increased immune evasion”.

"NB.1.8.1 is a mutated Omicron variant" shows you how misleading the Greek letter names have become.

Reminder that all Greek letters were given between May and November 2021 and none since.

Here's reality:
