What is the most common cause of acute viral rhinosinusitis?

• A. The flu virus
• B. The common cold virus
• C. Allergies
• D. Bacterial infections

Answer: (B)

The most common cause of acute viral rhinosinusitis is the common cold virus, primarily rhinoviruses and other respiratory viruses. These viruses are highly prevalent and are responsible for upper respiratory infections that can lead to the inflammation and swelling of the nasal passages and sinuses characteristic of rhinosinusitis. The common cold is often self-limiting, but it can trigger symptoms of rhinosinusitis when the sinuses become obstructed. While the flu virus does cause viral respiratory illness, it is less prevalent than the myriad of viruses that cause the common cold. Allergies can result in similar symptoms but are not infectious and do not lead to viral rhinosinusitis. Lastly, bacterial infections can lead to secondary complications in the setting of viral illness but are not considered the primary cause of acute viral rhinosinusitis. Thus, the common cold virus stands out as the primary culprit in this condition.
