Global Study of Viral Meningitis: A Systematic Review and Meta-analysis

Meningitis can quickly become a life-threatening sickness and therefore is considered a medical emergency. Viruses, after bacteria, are known as main pathogens involved in meningitis; therefore, we investigated the prevalence of viral meningitis worldwide and evaluated the clinical and preclinical features for rapid detection of viral meningitis. The results showed that the most prevalent viruses in viral meningitis are Enterovirus, Coxaci, Tick-borne encephalitis virus. Herpesviridae family; and the most prevalent viruses in aseptic meningitis are Echovirus, Enterovirus, Coxaci and HSV. The findings revealed differences in the prevalence of various viruses in these two types of meningitis, even though there was no significant difference in clinical manifestations between viral and bacterial meningitis. This indicates the importance of laboratory diagnostic methods for discriminating between these two types of meningitis.
