DNA virus mainly affects the upper respiratory tract

Dr Gupta further said: “Another observation - type B influenza (past two months 5 leading to PICU admission) has led to more severe pulmonary infections in form of ARDS, severe pneumonia requiring ventilation.”

He said that another virus which is leading to serious disease is adenovirus.
