Cross Ventilation Indoors Must To Stop Air-Borne Covid, Says AIIMS Chief

Dr Randeep Guleria said the virus has less of a chance spreading outdoors than indoors. In summer it is important to open all windows and have good cross ventilation, he added.

Dr Randeep Guleria -- chief of the prestigious All-India Institute of Medical Sciences -- today emphasised the need for good cross ventilation indoors in view of new research findings that Covid spreads through air and not through droplets as was initially supposed. A new article in medical journal Lancet has said the evidence that the virus is airborne is overwhelming and the safety protocol against it should be tweaked accordingly. Speaking to NDTV in the backdrop of a massive second surge of Covid that's registering more than 2 lakh fresh infections daily for the last four days, Dr Guleria said the virus has less of a chance spreading outdoors than indoors. In summer it is important to open all windows and have good cross ventilation, he added. "Your room should be very well ventilated. There should be good cross ventilation. Better to not have crowds or a meeting in a closed room," Dr Guleria told NDTV. In a closed atmosphere, even one infected person can infect everyone, he said.
