A dry cough is commonly associated with viral infections because these types of infections typically lead to irritation of the throat and respiratory tract without producing significant mucus. Viral infections such as the common cold or influenza can cause inflammation in the airways, leading to a persistent dry cough as the body tries to clear irritants. During these infections, the cough reflex is stimulated, often resulting in a non-productive cough that doesn't produce phlegm.

While asthma, bronchiectasis, and chronic bronchitis can also lead to coughing, they are often accompanied by other symptoms or types of cough. Asthma can cause a wheezing or tight-chest sensation and may produce a dry cough, but it can also result in a cough that brings up mucus at times. Bronchiectasis is characterized by chronic production of sputum due to airway dilation and dysfunction. Chronic bronchitis is a part of chronic obstructive pulmonary disease and is associated with a productive cough rather than a dry one. Thus, the condition most commonly linked to a dry cough is indeed viral infections.
