Right now it is not and unlocking continues. Also the numbers for the country as a whole, week on week, continue to fall.
Should there be a rise due to the Indian variant hotspots, it would have to be such a huge rise as to be of concern.

IF that should change it will be visible in the numbers.
So far the opposite is true.
