A body temperature of 37.4°C in a newborn can be considered a low fever, but the situation is not serious. The normal body temperature of newborns is usually higher than that of older children, especially in cases where the body produces more heat when wrapped in more blankets or eating milk, strenuous activity, crying, etc. For infants with fever not exceeding 38℃, physical cooling is usually recommended, including giving the baby more water to maintain sufficient body fluids and increase the amount of urine; wiping the affected child’s cheeks, forehead, armpits, palms and feet with a towel dipped in warm water; opening the bedroom window regularly to keep the room air fresh and reducing its clothing and covers appropriately. Parents are advised to go to the neonatal unit of the hospital promptly if they find that their child has a low fever lasting for more than 3-4 days, has poor milk intake, a stuffy nose, runny nose, cough, etc., or has a body temperature of 38.0℃ or higher during physical cooling and observation.
