People often think that a high fever will burn the brain and leave sequelae, but in fact that is because children have encephalitis, meningitis and other diseases, fever is only one of the symptoms of these diseases, what really affects the brain is caused by a serious infection lesion in the brain. A fever of 41 degrees Celsius or less will not cause direct damage to the brain or other organs of the patient, but a super high fever can sometimes cause varying degrees of abnormalities in consciousness. But ordinary fever will not exceed 41 degrees Celsius, so it will not burn the brain, and not the higher the fever, the more serious the condition. In particular, children over six months of age should not use the height of their temperature alone to determine the severity of their illness.
