More infectious Delta variant behind 2nd wave, says study

The Delta variant or B.1.617.2 strain, which was first detected in India, is more infectious than the Alpha variant or B.1.1.7, first detected in the United Kingdom. “Our data indicates B.1.617.2 shows high transmissibility and surges without any increase in case fatality rate (CFR). We estimate the transmissibility to be as much as 50% greater than B.1.1.7. Viral load of B.1.617.2 appears to be higher than B.1.1.7,” said their study in its conclusion.
