Mumbai: Three Delta-Plus variant sub-genens from the SARS-COV-2 virus are currently being circulating in the state, which, said experts, called for more epidemiological analysis to understand the impact on the ongoing virus transmission.
The recent Genome sequencing report shows the existence of 66 Delta-Plus cases in the state, which includes sub-lineage ay.1, AY.2 and AY.3.
The Delta variant that greatly transfers mutates into delta-pluses, is formed because Delta obtains an additional mutation called K417N in Spike protein, which increases the attachment of the virus to infected cells.
Now, scientists have found 13 sub-lines of delta-plus starting from AY.1, AY.2, AY.3 along the way until 13.
In Maharashtra, the first three sub-linings have been found so far.
Preliminary data has found Delta-Plus resistance to monoclonal antibody cocktail care.
There is little evidence until now to show it as transmitted by Delta, which continues to be the dominant variant.
In Mumbai, 11 cases, including the death of a 63-year-old child from the eastern suburb, has been reported.
From the deceased family, six contacts were tested positive for Covid-19.
Among them, two were also found positive for Delta-Plus.
One contact is a family member and other househelp, which is a slum population.
