Food for thought here. A strain thought to be almost exclusive to Hong Kong is killing about 280 people a day. Also just detected in Australia.

Those who got it wrong, for whatever reason, may feel defensive and retrench into a position that doesn’t accord with the facts.

The article names the HK variant BA.2.2, suggesting there also would be a BA.2.1...however [url]https://outbreak.info/situation-reports[/url] or https://outbreak.info/situation-reports - https://outbreak.info/situation-reports only has BA.2 without further sub-variants...

[url]https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#Sublineages_and_BA.2_subvariant[/url] or https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#Sublineages_and_BA.2_subvariant - https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#Sublineages_and_BA.2_subvariant ;Researchers have established the existence of three sublineages of Omicron. The 'standard' sublineage is now referred to as BA.1/B.1.1.529.1, and the two other sublineages are known as BA.2/B.1.1.529.2 and BA.3/B.1.1.529.3. https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#cite_note-PANGOLIN_B.1.1.529-47" style="text-decoration: none; color: rgb(6, 69, 173); background: none; - [47]  They share many mutations, but also significantly differ. BA.1 and BA.2 share 32 mutations, but differ by 28. https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#cite_note-For_21Jan2022-48" style="text-decoration: none; color: rgb(6, 69, 173); background: none; - [48]  This makes them as different as some other major variants, https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#cite_note-SSI_19Jan2022-49" style="text-decoration: none; color: rgb(6, 69, 173); background: none; - [49]  and it has been suggested that BA.2 should receive its own name based on the Greek alphabet. https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#cite_note-For_21Jan2022-48" style="text-decoration: none; color: rgb(6, 69, 173); background: none; - [48]  According to early research from the UK and Denmark in 2022, BA.2 is roughly 30% more transmissible than the original Omicron version, BA.1, and it currently accounts for about 1 in 5 COVID-19 infections globally, according to the World Health Organization. https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#cite_note-50" style="text-decoration: none; color: rgb(6, 69, 173); background: none; - [50]

also not very helpfull...But [url]https://www.coronaheadsup.com/asia/hong-kong/hong-kong-omicron-ba-2-with-si1221t-mutation-designated-ba-2-2/[/url] or https://www.coronaheadsup.com/asia/hong-kong/hong-kong-omicron-ba-2-with-si1221t-mutation-designated-ba-2-2/ - https://www.coronaheadsup.com/asia/hong-kong/hong-kong-omicron-ba-2-with-si1221t-mutation-designated-ba-2-2/ ;

The dominant BA.2 lineage in Hong Kong with the spike mutation at I1221T has been designated BA.2.2.

The BA.2 lineage has been split at a point that makes it easier to separate the Hong Kong variant from a BA.2 variant circulating in the UK that has a similar mutation.

South Korea is also seeing a similar large surge in cases to Hong Kong, reporting a record figure of 342,446 on the 8th March 2022, up 69% in one day.

DJ So //outbreak.info - outbreak.info may soon give info on BA.2.1 and BA.2.2 spread....

could be a warning....if it was not from november 2021....)
