What should I do if a child has a low-grade fever of 37.2°C?

A child's low-grade fever of 37.2°C usually requires treatment targeting the underlying cause. Common causes include physiological factors or pathological conditions such as influenza and tonsillitis.

I. Physiological Factors

A slightly elevated temperature may result from a high ambient temperature or intense physical activity, both of which can accelerate metabolism and increase heat production. Since this is a normal physiological phenomenon, specific treatment is generally not required. Increasing fluid intake appropriately, lowering environmental temperature, and getting adequate rest can help normalize body temperature gradually. Wiping the body with lukewarm water or taking a warm bath may also promote heat dissipation and improve the condition.

II. Pathological Factors

1. Influenza

If the fever is caused by influenza due to infection with adenovirus, parainfluenza virus, or similar pathogens, antiviral medications such as ribavirin granules, oseltamivir phosphate granules, or ganciclovir tablets should be used promptly under medical guidance to eliminate the pathogen and regulate body temperature. Additional measures like applying cooling patches or using warm compresses may also help improve fever symptoms.

2. Tonsillitis

If the fever results from an infection causing tonsillitis, treatment depends on whether it is acute or chronic. For acute tonsillitis, antibiotics such as azithromycin granules, cefaclor for oral suspension, or amoxicillin capsules are typically prescribed under medical supervision to suppress inflammation and relieve symptoms. For chronic tonsillitis, physicians may recommend physical therapies such as laser treatment or crypt irrigation to control the disease progression and help reduce fever.

In addition, other conditions such as bronchopneumonia may also cause low-grade fever. Following medical advice and receiving appropriate treatment can help lower body temperature.
