THIRUVANANTHAPURAM: Health authorities in Indiaare all set to do pool testing in a few of the 436 districts of the nation where no case of COVID-19 has been reported. This will probably be achieved to get a “realistic estimation” of the spread of the illness, according sources.

Into the third week of the 21-day lockdown, the authorities feel that without sufficient testing in the COVID-free districts, there may be an inherent danger in making any decision on the lifting of the lockdown. That’s the reason why info from two databases — from Aarogya Setu app and surveillance — will probably be merged to select the areas for pool testing.
