Covid: what is Orthos, this new variant of Omicron CH.1.1 that is spreading in Europe and is being monitored?

This new strain of Omicron, which has acquired a Delta mutation, could cause concern as it could be more pathogenic compared to other variants.

New data published earlier this week in the UK shows contamination of almost a quarter of the country’s cases with this new variant of Omicron, called CH.1.1 and called Orthus. This variant has also been detected in Spain, but also in India.

British health authorities explain that this new variant could be likely to become the majority and which could replace BQ.1.

Especially when he was present in 23.1% of the cases per January 7 as announced by the UK Health Safety Agency (UKHSA), as The Independent points out.

Why the nickname Orthos?

Like the Kraken, the legendary giant sea monster from Norse legends to qualify the XBB.1.5 variant, this new variant has also been given a nickname.

Orthos is a two-headed dog of Greek mythology. A nickname that suits him well since he is both a subvariant of the Omicron genus but with a mutation originating from Delta.

Symptoms and danger of this variant

Orthos as well as Kraken have been reported to have same symptoms as Omicron. Either the runny nose, headache, fatigue, sneezing, sore throat, among other things.

Orthos has a mutation called P681R – which was also on the Delta variant – and that could allow it better attack the cells and off cause more serious illness.

Researchers have also discovered that this variant has R346T, which is thought to help stuttering to fight the antibodies formed in response to vaccination or a previous infection, as reported by the Dailymail.

Like the Kraken, this new Orthos variant is not yet classified as “concerning”. But specialists are watching it closely to avoid a potential new wave of pollution.

Vaccination to protect yourself

Faced with these new new variants, it is therefore important to protect oneself with barrier movements as well as vaccination, which is highly recommended by scientists.

Especially to avoid a possible new wave.
