Are two ‘special surveillance,’ mutations identified on the most widespread form of the Indian variant of the sarscov2 virus: are many laboratories, even in Italy, which are studying them, reconstructing the 3d structure, while others get the sequences and compare them. To arouse all this interest is the suspicion that, in the light of the spread of the infection india, the culprit of the rapid spread of the virus is precisely this variant. It is also a question of whether it has not enough force to supplant the English one, currently the most widespread.
Of this variant, he said, “we know very little, we are studying it to verify the hypothesis that the two mutations can act in pairs.” A family of variantsthe variant that is studying is called B.1.617 and appeared in India in October 2020 with the variant B.1.618, which would seem less aggressive. To complicate the situation is the fact that B.1.617 already has a family, whose members are the three versions called B.1.617.1, B.1.617.2 and B.1.617.3.
A double mutation on the same proteinis therefore on these two ‘variants of the variant’ that is concentrating the attention of experts. Mutations that are studying are the 484 q, present in Brazilian variants (P.1) and South African (B.1.351.V2), and the 452 r, described in the Californian variant (B.1.429). To work to understand what is the Indian variant identified in Italythe variant B.1.617 has been reported so far in twenty countries; two cases established in Italy.
“At the moment we do not know what the Indian variant is identified in Italy: will be known only when the following is completed,” said ciccozzi. Zehender also notes that “the B.1.617 variant is still under investigation and one can still say very little in relation to its transmissibility and the effects on it have vaccines.
