This sub-lineage was earlier declared as a ‘variant of concern’. Other than the UK, the sub-lineage B.1.617.2 is prevalent in Maharasht-ra and different elements of India. Its presence, nonetheless, is but to be established in Telangana and Andhra Pradesh, although the principle variant, B.1.617, is current within the Telugu states. The UK variant B.1.1.7 can also be discovered within the Telugu states to a lesser extent.
In line with the most recent replace of novel coronavirus variants by Public Well being England, B.1.617.2 is assessed as not less than as transmissible as B.1.1.7 with reasonable confidence. That is biologically believable based mostly on the mutation profile. “It may possibly compete with B.1.1.7 within the inhabitants and modelled progress estimates, suggesting transmissibility not less than equal to B.1.1.7,” the UK well being company stated.
Referring to its neutralising potential towards recognized Covid-19 vaccines, the report stated as of now there’s inadequate information to evaluate the potential for immune escape.
“B.1.617.2 has unfold quickly in India based mostly on out there information. In some areas, S gene goal information sugges-ts that this variant could also be extra frequent than is indicated by the present sequence information, as a result of lag in sequencing, and will have changed B.1.1.7 to some extent. Modelled progress estimates counsel that the variant is not less than as transmissible as B.1.1.7,” the report added.
