Viral sinusitis can cause similar symptoms but is typically associated with milder systemic symptoms and often does not present with significant fever. Allergic rhinitis, on the other hand, is characterized by clear nasal drainage, itching, and sneezing, with little to no fever, which makes it less likely in this case.

Bacterial sinusitis is often preceded by a viral upper respiratory infection and occurs when the sinuses become infected following an initial viral illness, manifesting as longer-lasting symptoms, including purulent nasal discharge, facial pain, and fever.

The common cold, while it can also present with fever and nasal congestion, usually resolves within a few days and is often not associated with significant fever in older children. Given the child’s age and symptomatology, the likelihood of bacterial sinusitis as the cause of fever and nasal congestion is considerably higher. Thus, the combination of fever and
