New Delhi: Union Health Minister Harsh Vardhan on Thursday said almost 80 per cent of the COVID-19 cases in India are asymptomatic or at best with very mild symptoms.

In an exclusive interview with IANS, the Health Minister said, "Even today, in almost 80 per cent of the cases of COVID-19, which are being reported in India, the patients tend to exhibit either nil or mild symptoms. These patients are mostly contacts of confirmed cases. Interestingly, had it not been for our contact tracing efforts, and if left to their own in isolation, these patients may not have even remembered or reported their infection."
