Cough lasting up to 3 months baffles medical practitioners this flu season

Family physician Dr Hillary Rodrigues said, "The cough is normally dry and gets worse while lying down. It is more pronounced at night and early morning. One of the reasons could be the increasing levels of pollutio. Smog is toxic to the lungs. Other reasons could be the extreme difference in day and night temperatures. Many asthmatic and senior citizens come up with severe cough, respiratory distress and wheezing."
