Meningitis is often caused by bacterial infection and is a very important disease in childhood, with the potential for serious sequelae, and must be carefully monitored for early detection and treatment. So, what are the main symptoms of meningitis? First of all, most cases of encephalitis are febrile. Fever is a typical symptom in the early stages of encephalitis, and this fever is difficult to explain by infections in other parts of the body. For example, if the child has pneumonia at the same time, but the infection in the cough and lungs does not look very heavy, and the fever is very heavy, it is important to consider whether there are other causes that can cause fever, such as encephalitis. Secondly, due to the increased intracranial pressure, some children may also experience vomiting, which is often described as jet vomiting, but in reality the child’s vomiting may be atypical. The child’s neck may seem a little stiff and not allow lifting. As a result of damage to one area of brain tissue, there may be abnormalities in movement or other abilities in that area. In addition, headache, dizziness, drowsiness, and coma may also be present to varying degrees. When there is a simple headache, it is important to consider whether there is an increase in intracranial pressure, and when there is a problem with the level of mental consciousness, the drowsiness that occurs when the child is awakened and falls asleep again must be taken more seriously. In conclusion, meningitis is a very important disease that may leave serious neurological sequelae, and early manifestations must be taken seriously.
