Yes this is right due to pollution at many level the Delhites have developed immunities. Covid had come to city from all directions but due to our internal strength we came over it. Mostly persons were working in field due to any reasons so it became easy. Sitting at home was right for some days to break chain but for months it was burden on country and individuals. more
