Dr Pooja Khosla, senior consultant (Department of Medicine), Sir Ganga Ram Hospital, said the second wave of the coronavirus has taught us that cases can increase suddenly.

“There are warning signs from different parts of the world. In India too, a small increase in cases has been recorded. Infections can increase exponentially anytime. I think one should not assume anything and make all efforts to prevent a second wave-like crisis, which was a nightmare,” she said.

“Opening everything is not appropriate everyone has been saying the third wave is a couple of days away,” Dr Khosla added.
