WHILE a large number of people now have immunity against coronavirus due to previous infections or vaccination, a guarded approach is needed in terms of implementing restrictive measures to avoid a second wave-like crisis, experts said. Dr Yudhyavir Singh, who has been managing the COVID-19 ICU at AIIMS New Delhi, said it is important to lift a few restrictions to resume economic activities when cases are low. Dr Singh added that Delhi may have already achieved herd immunity, considering the massive number of cases seen during the second wave.

 

However, 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.
