How's that travel ban working? It's already in the community you muppets.


Another 75 cases of the super-mutant Omicron variant have been identified in England, health officials confirmed, after it was revealed that the majority of sequenced infections of the new variant are in fully vaccinated people.

The news came as Boris Johnson insisted last night that he wanted Britons to enjoy Christmas as ‘normally as possible’ – just as Ireland was told it was going into semi-lockdown.

Following a week of mixed messaging from his ministers, the Prime Minister admitted there had been ‘quite a lot of to-ing and fro-ing’ on Christmas parties.

But he said it was ‘not right’ that people should consider cancelling seasonal events – saying that the ‘tough measures’ his Government has taken at the borders should see the country through without the need for further curbs.

It came as Ireland closed nightclubs, imposed restrictions on bars and restaurants and placed curbs on household mixing to slow the spread of the Omicron variant.

Last night it was claimed that the UK’s travel red list could be expanded this weekend with arrivals from Nigeria facing the prospect of hotel quarantine.

Ministers on the Cabinet’s Covid operations sub-committee could meet as early as tomorrow to decide whether to introduce more restrictions.

Today's new cases bring the total number of confirmed Omicron infections in England to 104, while the total for the whole of the UK now stands at 134, the UK Health Security Agency (UKHSA) said.

Cases of the new variant have been identified in the East Midlands, East of England, London, North East, North West, South East, South West and West Midlands.

An interesting read: https://www.science.org/content/article/where-did-weird-omicron-come

The most interesting bit for me was this:

Omicron clearly did not develop out of one of the earlier variants of concern, such as Alpha or Delta. Instead, it appears to have evolved in parallel—and in the dark. Omicron is so different from the millions of SARS-CoV-2 genomes that have been shared publicly that pinpointing its closest relative is difficult, says Emma Hodcroft, a virologist at the University of Bern. It likely diverged early from other strains, she says. “I would say it goes back to mid-2020.”

Lol they instituted a travel ban and quarantine measures and removed them when they thought it appropriate to do so - just like all other counties have?
I think more of this will happen as the world gets further information on Omicron and what appears to the the good news that its not as ravaging as Delta.

The same genetic sequence appears many times in one of the coronaviruses that causes colds in people - known as HCoV-229E - and in the human immunodeficiency virus (HIV) that causes AIDS, Soundararajan said.

There are a number of interesting and provocative points in that article:
- In some ways it's a lot like the original 'China' outbreak, that seemed to come out of nowhere, but had clearly been in circulation before being noticed.
- Extensive surveillance in SA means it probably didn't orignate locally, even though the breakthrough event took place here.
- An animal reservoir is possible, but unlikely due to the huge number of human infections.
- Prolonged infection in an immunocompromised patient is the most likely explanation.
- Vaccines (low or high percentages) likely have nothing to do with the development of mutations and variants.

Edit: Forgot to link the very interesting variant relationship chart (can't embed the image). https://www.science.org/do/10.1126/science.acx9754/full/_291121_nid_omicron.svg

If true that's pretty rare for Covid, which has unusually good proofreading transcription. Not much scientific coverage (so far), other than a single preprint on a site that I am not familiar with: https://osf.io/f7txy

Yeah plenty to digest and several contrasting viewpoints. The only conclusive thing I got out of it is that this has been evolving separately in the dark for a while. Perhaps it only recently acquired the necessary mutations to make it highly transmissible?

Yeah also not familiar with that site. We also need to be cognisant of the fact that the media is hungry for Omicron related news of any kind.

The political theatre of the UK's travel ban on South Africa

We call on the UK and other governments to reverse their damaging travel bans and follow the advice of WHO and the International Health Regulations in keeping international borders open.

Instituting public health measures to identify and manage cases of the omicron variant would be a far better investment. The UK in particular is damaging the economy of South Africa by its actions. Countless families in many countries have once again had their plans dashed by the decisions of politicians who want to be seen to be doing something rather than focusing on what they should be doing—meaningfully supporting global COVID-19 vaccination efforts.
