In this case, the child often has no symptoms of fever, and the child’s mental state is relatively okay. Second, it is caused by an infection of the central nervous system. If the child has a viral or bacterial infection that attacks the child’s brain, the child causes acute encephalitis. In this case, the child will also have convulsions and is often accompanied by drowsiness, frequent vomiting and fever. In this case, the child should be given timely anti-infective treatment, such as the application of cephalosporin, and to reduce intracranial pressure, to apply mannitol dehydration.
