Which symptoms are commonly associated with bronchiolitis?

Bronchiolitis is primarily a viral infection that affects the small airways or bronchioles in the lungs, most commonly seen in infants and young children. The hallmark symptoms typically include fever, cough, and wheezing.

Fever often signifies the body's response to an infection, while a cough is a common reaction to irritation in the respiratory tract. Wheezing, a whistling sound during breathing, indicates narrowing of the airways due to inflammation and congestion, which are characteristic of bronchiolitis. These symptoms correlate directly with the disease's pathophysiology, reflecting both the inflammation and the resultant airflow obstruction that occurs.

In contrast, the other options present symptoms that are not typically associated with bronchiolitis. Chest pain and dizziness are more often linked to cardiovascular issues or pulmonary conditions but not specifically to bronchiolitis. Rash and swelling are indicative of allergic reactions or other dermatological conditions rather than a respiratory infection. Nausea and vomiting can arise from numerous gastrointestinal issues but are not commonly connected with bronchiolitis. Therefore, the combination of fever, cough, and wheezing stands out as the correct representation of the symptoms associated with bronchiolitis.
