Which type of sinusitis is typically caused by a bacterial infection following a cold?

• A. Chronic sinusitis
• B. Acute bacterial sinusitis
• C. Viral sinusitis
• D. Allergic sinusitis

Answer: (B)

Acute bacterial sinusitis is most accurately described as occurring after a viral upper respiratory infection, such as the common cold. In this sequence, the initial viral infection can lead to inflammation and swelling of the sinus membranes, which may subsequently impair drainage and create an environment conducive to bacterial growth. As this condition progresses, bacteria that are normally present in the nasal cavity can overpopulate and cause a secondary infection, resulting in the symptoms typical of acute bacterial sinusitis. Chronic sinusitis refers to a prolonged inflammation of the sinuses, often lasting more than 12 weeks, and while it can have bacterial involvement, it does not specifically follow an acute viral infection as acute bacterial sinusitis does. Viral sinusitis is primarily caused by viruses and typically resolves without the need for antibiotic treatment, distinguishing it from the bacterial variety, which tends to require different management approaches. Allergic sinusitis arises from allergic reactions rather than infections and does not directly follow a cold. Thus, the association between acute bacterial sinusitis and the post-viral infection scenario makes it the correct answer.
