Tonsillitis is a common childhood disease that occurs when the seasons change and the temperature changes. The immune function of the baby’s body is not yet complete, and inflammation of the tonsils is more common in children aged 2-6 years. The tonsils are the gateway to the respiratory tract and are the first to be invaded by bacteria and viruses from the nose and mouth. Children with acute episodes of pediatric tonsillitis will show symptoms of high fever. Children with fever that lasts for more than 5-7 days need to go to the hospital to clarify the cause through routine blood tests and bacterial culture tests and treat the symptoms. If the baby’s body temperature is below 38.5 degrees Celsius, you can not take antipyretic drugs, but only need to take physical cooling, and pay attention to keep the indoor air circulation, temperature and moderate appropriate, and use warm water to help the baby rub the body, let the baby drink more water, sweat more, urinate more, and reduce the body temperature. When the sore throat is severe or high fever (body temperature greater than 38.5°C), oral antipyretics can be taken. You can take antipyretic medicine or plug antipyretic suppositories to lower the temperature. At this time, you should promptly consult a hospital to find out the cause of the fever and clarify whether there is a viral or bacterial infection, if it is caused by a virus, it can be treated with antiviral drugs; if it is a bacterial infection, it can be treated with antibacterial drugs. If the baby has a history of febrile convulsions, it is recommended that when the body temperature is greater than 38.0°C, oral antipyretics and warm water should be added to bring down the fever in time to avoid the baby’s high body temperature causing febrile convulsions.
