New Delhi:
A brand new coronavirus variant – B.1.1.529 – has been red-flagged by scientists globally over an alarmingly excessive variety of spike mutations which may make the virus extra proof against vaccines, enhance transmissibility and result in extra extreme signs.

Listed here are 10 issues to know concerning the new COVID-19 variant:

  1. The B.1.1.529 variant has 50 mutations general, together with greater than 30 on the spike protein alone.

The Delta Plus variant that mutated from the latter was characterised by the K417N mutation on the spike protein; this mutation has been linked to immune escape, however it’s unclear if that is among the many mutations in B.1.1.529.

  3. There may be hypothesis on the variant’s origin, however it might have developed from a single affected person. Francois Balloux, the Director of the London-based UCL Genetics Institute, has steered it might have come from a continual an infection of an immuno-compromised individual, who might presumably be an untreated HIV/AIDS affected person.

Their samples returned “very excessive” viral masses, epidemiologist Dr Eric Feigl-Ding tweeted this morning. “PCR Ct values of 18 and 19… insanely excessive contemplating they have been adverse on current PCR assessments,” he stated.

  6. As a result of the sufferers have been in separate rooms, there may be concern this variant is airborne. “… appears like vaccine evasion may very well be actual with this variant… and sure, it is rather airborne. Resort visitors have been in several room throughout the hallway. Environmental samples discovered the virus in 25 of 87 swab throughout each rooms,” Dr Feigl-Ding tweeted.

  7. On Thursday India referred to as for rigorous screening of passengers from these international locations. “This variant… has severe public well being implications in view of just lately relaxed visa restrictions and opening up of worldwide journey,” the ministry stated.
