6. What Are the Causes of Upper Respiratory Infections?

Viruses generally cause upper respiratory infections such as the common cold and influenza. Treatment targets symptoms rather than the cause, leaving the body's immune system to fight the infection at the source. Common symptoms of an upper respiratory infection include a runny nose, post-nasal drip, cough, and nasal congestion.
