Contrast this with the subsequent highest worth of R in the course of the starting of the primary wave, 2.51 (March 14-April 5, 2020),” he added.

Asked in regards to the implications of the rise in R-value for Covid trajectory, Sinha mentioned “it can go either way”.

“Going forward, whether this leads to another huge increase in cases depends on prompt actions taken by the public at large which seems to have stopped adopting basic precautions like wearing masks and avoiding crowds,” he added.

“We need to again insist that everyone wears masks, practice basic hygiene (like washing hands and avoid touching one’s face,eyes), physical distancing as much as possible, etc.”
