Pediatric patients reportedly acquire COVID-19 either through close contact with infected family members (89%), exposure to endemic areas (33%), or both (22%); with the majority (53%) showing moderate symptoms and no severe or critical cases [2] . We do not endorse the idea of letting the epidemic a free hand in order to create sufficient herd immunity to end the epidemic;as it would entail an enormous burden on the healthcare system -United Kingdom, at first, considered a different approach -of unrestricted spread of disease without any brakes applied, but public health experts were able to convince the government to accept the more reasonable mitigation approach. The proportion of the population that should be exposed to the virus for herd immunity to be effective is calculated as 1-1/Ro. In the absence of serological studies, the true extent of spread of SARS-COV-2 in India is unknown.	./cache/cord-299308-gza1pwx6.txt	./txt/cord-299308-gza1pwx6.txt
