When children develop acute upper respiratory infections, the main focuses are to ensure plenty of rest, clear the exterior and reduce heat, and prevent complications. During fever, it is advisable to give liquid or soft foods, encourage increased water intake, and for infants, feed small amounts frequently to avoid symptoms of digestive upset like vomiting and diarrhea. Maintain room temperature between 18 to 22 degrees Celsius, and keep a certain level of humidity. If there is excessive nasal and pharyngeal secretion, a prone position can be helpful. For high fevers, initially use a cold towel to moisten the forehead and the entire head, or use fever patches or a warm bath to alleviate discomfort and prevent febrile convulsions. It is beneficial for the baby to drink more water to replenish the bodily fluids lost due to fever and to facilitate the elimination of toxins. Adequate hydration can help thin the secretions in the nasal passages, making them easier to clear. Medication can also be used for treatment.
