The causes can be divided into two categories of infectious and non-infectious. Very few non-infectives, mostly caused by the virus infection. Aseptic meningitis is now synonymous with viral meningitis. The cause of non-infectious due to allergic factors, malignant tumors, various toxic substances and so on. In addition to the causes of infectious virus, there are rickettsia, spirochetes, fungi, protozoa, mycoplasma, early tuberculosis and so on. However, the overwhelming majority of cases are caused by viruses. Mainly caused by enterovirus and mumps virus.
