Covid-19: India may need to rework 'test, trace, isolate and treat' strategy - Economic Times

Testing can be beneficial if early identification of Covid-19 warrants specific management strategy or medical intervention, Lahariya said, adding that when in the case of Covid-19 treatment is mostly symptomatic, therefore, it doesn’t make sense to test asymptomatic contacts.

To Lahariya, even from a public health perspective, testing on a mass scale was not required as Covid-19 has already spread to the community level.

Instead, we should focus on vaccinating maximum people because data suggests that the unvaccinated are at highest risk to develop severe symptoms or die due to Covid-19 caused by the new variant."
