Another common symptom of upper respiratory tract infection is cough. Cough is an illness that does not normally cause any alarms or hazards. Most people who experience cough do not treat it as a threat and usually allow it to recuperate on its own without consulting a medical professional. During the earlier periods, the lack of knowledge and medical treatments for cough caused fatalities to other people.
A cough may also be associated with other serious illnesses such as chronic obstructive pulmonary disease, asthma, gastroesophageal reflux disease, tuberculosis disease, and more. As our bodies have adapted to regular coughs, proper hydration and over-the-counter medications may suffice; however, if you have a persistent cough for weeks, consult your doctor for treatment.
