Acute bronchitis is a lower respiratory tract infection in which the bronchial tubes, the larger airway of the lungs, become inflamed and filled with mucus. Viral infections account for the majority of acute bronchitis cases, whereas bacterial infections are uncommon. Upper respiratory tract infections, like the common cold, can sometimes lead to acute bronchitis.[1][2]
