Eight of these mutations affect the spike protein that makes it highly transmittable as compared to the previous mutation. The new Covid-19 strain, dubbed as B.1.1.7, can be 70 per cent more transmissible than the earlier one.
The CSIR-Centre for Cellular and Molecular Biology (CCMB) in Hyderabad, which is among the ten research institutes tracing the new Covid-19 strain in India, says the new strain has not worsened the Covid-19 symptoms so far in India.
