Vehicular pollution, important reason for rise in asthma cases

Vehicular pollution is the major reason for increase in asthma cases, say city doctors on World Asthma Day which falls on the first Tuesday of May every year (May 6). A majority of respiratory physicians in the city say that out of the total number of out-patients, around 50 per cent suffer from asthma. It is a lung disease that narrows the airways thereby causing recurring periods of wheezing, chest tightness, and cough that normally occurs at night or early in the morning.
