"I believe the new Ba.2.75 sub-variant identified in India and other countries is worth keeping an eye on as it may be even more contagious than Omicron 5 and have a high capacity to infect, cured and vaccinated people. Eye without alarm".
Matteo Bassetti
, director of Infectious Diseases of the San Martino hospital in Genoa
writes on Twitter .
Virologist
Tom Peacock
, of Imperial College London, of the same opinion.
Reported in India on June 2, the sub-variant BA.2.75 is "apparently rapidly growing," Peacock said in a tweet.
There are currently no scientific publications on this newcomer of the Omicron family, but reports on the web among groups of experts, who above all reveal how this new sub-variant is a second generation, derived in turn from Omicron BA.2 but different from this one due to of
nine mutations on the Spike protein
, with which the virus attaches itself to human cells.
Precisely because of the latter, which probably make it more transmissible, it was preferred to distinguish it from BA, 2 "It is worth keeping an eye on," notes Peacock.
Another probable feature is the
speed
with which it has spread over the course of a month from India to Germany and Canala to New Zealand.
However, it is too early to draw conclusions, Peakok observes, considering that the "sequences collected so far are few".
