Dr Manish Mannan, HOD, Paediatrics & Neonatology, Mother & Child Unit at Gurugram's Paras Hospitals, says that any human being who has underlying comorbidity, whether it's bronchitis, bronchial asthma, can increase the morbidity of the lungs. However, Dr Mannan says that the number of kids having respiratory system getting affected and requiring a CT-scan is much less.
