10 Signs and Symptoms of RSV
Reviewed: Dr. Mera
Symptom #2: Cough
A cough is a repetitive and sudden reflex that functions to clear the airways from irritants, pathogens, and foreign particles. Frequent coughing indicates that there is an underlying disease. Bacteria and viruses have evolved by benefiting from this reflex as the host helps to spread the disease by coughing.
Besides an infection (such as in an RSV infection), a cough can also occur in asthma, air pollution, smoking, post-nasal drip, gastroesophageal reflux, lung tumors, and heart failure. Treatment of cough depends on the underlying cause.
