Fever in an infant.

CASE This 3-month-old male infant presented to our emergency room with fever of up to 1008F and a runny nose for 1 day. The discharge from the nose was clear to white. At the same time, there was no change in the patient’s feeding pattern, and the mother further stated that breathing was really no different from how it had been before the onset of fever. However, the mother thought the infant looked a little sick to her. The patient had contact with 1 cousin who had cold symptoms, and the mother administered an antipyretic 2 times a day to the infant after the infant seemed to develop such symptoms. The patient’s medical history was rather benign because this was only the second time the patient was ill with any problem. The previous illness also centered around an upper respiratory tract infection. On physical examination, the patient’s temperature was 37.28C. The pulse rate was increased to about 100 beats per minute, and the respiratory rate was 50 breaths per minute, both signs of distress, but still, the blood pressure was normal. Examination of the ears demonstrated a normal left ear and a right ear blocked by wax. No adenopathy was present in the neck and on auscultation; minimal coarse breath sounds were heard, a little more pronounced on the left. The patient was mildly tachypneic but demonstrated no retractions. The remainder of the physical examination was normal. The total white blood cell count was 8300/mL, and the differential consisted of 7% segmented neutrophils, 8% bands, 74% lymphocytes, and 2% atypical lymphocytes. Urinalysis was normal. As is usually the case, radiographs of the chest were obtained to exclude pneumonia (Fig. 1). After the radiograph examination was taken, the patient was placed on antibiotics for pneumonia. What do you think about all of this?
