New Delhi, Aug. 1 -- The rate at which the COVID-19 infection spreads has increased in India and it is now a major concern, said AIIMS chief, Dr. Randeep Guleria in an interview to NDTV on Saturday.

"Starting from .96, and going all the way up to 1, the rise in R-Value is a cause of concern.

The R-Factor is an indicator of theeffective reproductive number of a virus.
