Nearly 1,500km (932 miles) away, in the western city of Pune, Dr Aarti Kinikar, a paediatrician working in a government medical college and hospital, has seen 30 such cases since April. Thirteen of the sick children, aged four to 12 years, are still in hospital. Most of them have suffered from myocarditis, a disease marked by the inflammation of the heart muscle. “The numbers are too many after the second wave,” Dr Kinikar said.
