“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”.
He writes it on Twitter Matteo Bassettidirector of Infectious Diseases of the San Martino hospital in Genoa.
The virologist of the same opinion Tom Peacock, of Imperial College London. 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 from nine mutations on the Spike proteinwith 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 in the space of a month it spread from India to Germany and Canala, up to New Zealand. However, it is too early to draw conclusions, Peakok observes, considering that the “sequences collected so far are few”.
