Question

What is second wave of covid-19 ??​

Answer 1

Answer:

Large parts of Europe are in a second lockdown as a new wave of infection sweeps through the continent. Cases in the US are smashing new records. But overall numbers in India are falling — for reasons not yet fully clear. What is the way forward, given the cost of lockdowns? In an interview to The Indian Express, Professor Sunetra Gupta, a proponent of herd immunity, weighed in on this and related questions.

Answer 2

Answer:

Corona Virus constantly mutates hence a new strain often appears once the first strain has had its impact. This second strain causes the second wave of covid-19.
