The second is that the child gets cold again during the recovery from pneumonia, the possibility of secondary infection is less, such as cold, the temperature has been repeated, you need to adjust the medication, plus antiviral drugs to treat the cold, keep warm, drink small amounts of water several times, you need to combine the temperature. If the body temperature does not exceed 38.5℃, no medication is needed for the time being, and physical cooling is sufficient.
