According to WHO, the Indian variant (B.1.617) of the coronavirus was detected in October. Subsequently, three subspecies were identified: B.1.617.1, B.1.617.2 (“delta”), and B.1.617.3. They differ in several mutations in the spike protein. The greatest concern among scientists is the “delta” strain. It continues to mutate, recently it became known about the appearance of the “delta-plus” strain (B.1. 617.2.1).
