New Delhi:

A brand new coronavirus variant – B.1.1.529 – has been red-flagged by scientists worldwide over an alarmingly excessive variety of spike mutations that may make the virus extra immune to vaccines, enhance its transmissibility and result in extra extreme Covid signs.

First recognized in South Africa in the beginning of this week, the pressure has already unfold to neighbouring nations, together with Botswana, the place it has been detected in totally vaccinated individuals.

Two circumstances have additionally been detected in Hong Kong – the place two travellers arriving from elements of southern Africa had been quarantined, in step with native legal guidelines, in separate rooms.

Samples from the 2 contaminated individuals in Hong Kong returned “very high” viral hundreds, epidemiologist Dr Eric Feigl-Ding tweeted this morning. “PCR Ct values of 18 and 19… insanely high considering they were negative on recent PCR tests,” he mentioned. What is extra worrying is that the sufferers have been in separate rooms, suggesting the brand new variant is airborne.
  3. The B.1.1.529 variant has 50 mutations total, together with greater than 30 on the spike protein alone. The spike protein is the goal of most present vaccines and which the virus makes use of to unlock entry to our physique’s cells. There are 10 mutations on the receptor binding area of the variant in comparison with simply two for the Delta variant that induced havoc worldwide.
  4. “We don’t know very much about this (variant) yet. What we do know is that this variant has a large number of mutations, and the concern is that when you have so many mutations it can have an impact on how the virus behaves,” Dr Maria Van Kerkhove, WHO’s COVID-19 Technical Lead, mentioned, underlining the significance of an entire dose of vaccination.
