The second wave of Covid, is in which the numbers are skyrocketing, is hitting younger people and children - unlike the first round when the elderly, and those with co-morbidities were seen to the most vulnerable sections.
Data from the Union health ministry shows 79,688 children have been infected in the five states affected worst by the virus in India.
In Maharashtra, 60,684 children have been infected with Covid between 1 March and 4 April. Of these children, 9,882 are under the age of five years.
In Chhattisgarh, 5,940 children have been infected by the disease - 922 of them are below the age of five. In Karnataka, the corresponding figures are 7,327 and 871. In Uttar Pradesh, 3,004 children have been infected and 471 among them are below the age of five.
A doctor in Delhi's Ram Manohar Lohia hospital has said the national capital is seeing a similar situation. Health ministry figures show Delhi logged 2,733 infections among children, 441 of them below the age of five years
Public health experts are of the view that the weaker immunity in children, coupled with a lack of Covid-appropriate behaviour, could be the reason for the spike. There is also the fact that new virus mutants are highly transmissible, and are turning into super-spreaders.
