Covid-19: all about the new Omicron subvariant worrying England

A new Omicron subvariant, CH.1.1, has appeared in England. According to the health authorities, it can be more pathogenic than other varieties and should be closely monitored.

Also known as ‘Orthrus’ or ‘Orthro’, the new sub-variety of Omicron is gaining more and more presence in the UK. Like its nickname, which refers to the mythological dog with two heads, CH.1.1 worries. This strain was discovered in November in Leicestershire, England and is only growing. While it was present in just 1% of analyzes recorded by the Sanger Institute on November 12, it has now been found in 23.3% of tests across the UK. 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 headache, sore throat or even cough, a mutation of the latter, called P681R, may 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 antibodies generated in response to vaccination or previous infection. Like the XBB.1.5 subvariant, also called “Kraken”, found in the US territory, CH.1.1 may become a dominant strain of Covid-19. For now, however, experts believe that there is no cause for concern due to the high number of vaccinations and previous infections in Europe.
