Febrile illness in children is one of the most common reasons for seeking medical care and requires careful evaluation and management due to the risk of underlying serious infections. Fever itself is not a disease but a physiological response to infection, inflammation, or other pathological conditions. Management focuses on identifying the cause, relieving symptoms, preventing complications, and ensuring adequate hydration and nutrition. The initial step in management involves a thorough assessment, including history taking and physical examination. Important aspects include the duration and pattern of fever, associated symptoms such as cough, vomiting, diarrhea, rash, or convulsions, and any recent exposure to infections. Age is a crucial factor, as infants, especially those under three months, are at higher risk of severe bacterial infections and require prompt evaluation. Monitoring vital signs such as temperature, pulse, respiratory rate, and blood pressure is essential.
