Norway is seeing the world’s first omicron superspreader event after a party downtown Oslo last Friday. Of 120 healthy non-symptomatic fully vaccinated individuals with a negative test, two had recently returned from South Africa and turned out to be positive, omicron. 1/

Now some 80-90 of the 120 are PCR pos, 13 of these confirmed omicron, the rest waiting for sequencing results. Some of those infected w omicron were not at the party but present at the same restaurant that evening. Not looking good re transmissibility. reuters.com/world/europe/o…

Update. Min. 60 at the party infected. Now nearing 100 cases in total that night, some not with the party but present at the same venue. Screening (likely S gene dropout PCR): about 50 suspected Omicron, the rest not yet screened. 13 confirmed Ο. nrk.no/norge/fhi_-19-… (paywall)

A total of 19 cases of Omicron verified in Norway by now, around Oslo & elsewhere. Green: No suspected cases. Yellow: Suspected cases. Red: Verified cases (see the tiny red dot on the west coast) dagbladet.no/coronavirus

Almost 120 people are now infected after the party downtown Oslo Nov 26. Around 70 were with the party of 120, 45-50 other guests at the same venue. Omicron suspected in all, still only verified in 13, sequencing slow, screening underway @Folkehelseinst dagbladet.no/nyheter/kan-ik…

Now also a superspreader event in Denmark - 53 Omicron cases (15 found by sequencing, 38 by s gene dropout) after a party with 150 participants

And more: In Denmark, altogether 183 cases are now confirmed, 32 by sequencing, the rest by variant PCR (this method now found to be sufficiently precise by Statens serum Institut SSI). Denmark now reports ongoing transmission among people not traveling ssi.dk/aktuelt/nyhede…

In UK, another superspreader event. Looks like we’ll see many of these with Omicron in circulation (and unfortunately, that O will spread very fast as long as we allow for such events to happen). Fortunately all cases mild here, too; positive, although way too early to conclude

And as a natural consequence:
