The Prevalence of Viruses in the Cerebrospinal Fluid of Children with Aseptic Meningitis in Shiraz, Iran

Objectives: The current study aimed to evaluate the causative agents of viral meningitis through real-time PCR among children with aseptic meningitis. Methods: Children aged 1 month to 16 years with suspected viral meningitis were enrolled in this study (March 2014-February 2015). Cerebrospinal fluid samples were analyzed by real-time PCR for detection of enterovirus, mumps, measles, adenovirus, EBV, CMV, VZV, hhv 6, and rubella viruses. Demographic information, laboratory data, and clinical presentations of patients were also collected. Results: Of 56 patients suspected to viral meningitis, 21 (38.9 %) had a positive PCR result. Enterovirus (42.85%) and mumps (38.1%) were the most prevalent viruses, and VZV and measles were not detected. Three children were coinfected with enterovirus/hhv6, enterovirus/EBV, and mump/adenovirus. Fever, headache, and nausea/vomiting were the most common symptoms in children. The rates of symptoms were not statistically significant among children with positive and negative PCR tests. Conclusions: In the present study Enterovirus and mumps viruses were the most common causes of viral meningitis in children. PCR, as a rapid test for the diagnosis of viral meningitis, can be used to decrease hospitalization length.
