Covid-19: all about the new Omicron sub-variant that worries England

A new Omicron sub-variant, the CH.1.1, has popped up in England. According to health authorities, it could be more pathogenic than other variants, and should be monitored closely.

Also known as ‘Orthrus’ or ‘Orthro’, the new sub-variant of Omicron is gaining more and more presence in the UK. Like its nickname, which refers to the mythological dog with two heads, the CH.1.1 worries. Detected in November in Leicestershire in England, this strain is only growing. While it was present in only 1% of the analyzes recorded by the Sanger Institute on November 12, it is now found in 23.3% of tests across the United Kingdom. CH.1.1 has also been detected in India and Spain.

A worrying change

If the CH.1.1 subvariant triggers the usual symptoms such as headaches, sore throats, or even coughs, a mutation of the latter, called P681R, could be more dangerous. Also present in the Delta variant, the latter attacks the cells more violently, and can therefore trigger more serious diseases.

According to Dailymail, scientific studies also reveal that this variant has R346T, which is intended to help the strain fight off antibodies generated in response to vaccination or previous infection. Like the XBB.1.5 subvariant, also called “Kraken”, present on United States territory, CH.1.1 could become a dominant strain of Covid-19. For the time being, however, experts believe that there is no reason to worry because of the high rates of vaccinations and previous infections in Europe.
