From 100 samples sent in June, 73 Delta Variants and 1 each of Alpha and Eta variants were found. The results of 150 samples sent in July are still awaited.
The results of samples sent to the National Institute of Biomedical Genomics (NIBMG), Kalyani, West Bengal take a longer time as all the 8 states of the NorthEast send their samples to the same institute. Delta variant is present in almost all countries. The alpha variant has been confirmed in 175 countries while Eta Variant has been confirmed in 67 countries.
