title: Viral etiology of aseptic meningitis among children in southern Iran.
abstract: Aseptic meningitis refers to a clinical syndrome of meningeal inflammation in which bacteria cannot be identified in the cerebrospinal fluid (CSF). The viral etiology and the epidemiological, clinical, and laboratory characteristics of aseptic meningitis among children aged 2 months to 15 years in Shiraz, southern Iran were determined. From May 2007 to April 2008, 65 patients were admitted to the hospital with aseptic meningitis. Seven viruses, non-polio human enteroviruses, mumps virus, herpes simplex virus (HSV), varicella-zoster virus (VZV), human cytomegalovirus (HCMV), human herpes virus type 6 (HHV-6), and Epstein-Barr virus (EBV) were investigated by polymerase chain reaction (PCR) method. Viruses were detected in 30 (46.2%) patients in whom non-polio human enterovirus and mumps virus were detected in 13 (43.3%) and 11 (36.7%), respectively. The remaining 6 (20%) of the cases were caused by HSV, VZV, HCMV, and HHV-6. Haemophilus influenzae and non-polio human enterovirus were detected in one patient simultaneously. Viral meningitis was found to be more frequent during spring and summer. The majority (66.6%) of the patients were treated in the hospital for 10 days and had received antibiotics in the case of bacterial meningitis. Rapid diagnosis of viral meningitis using PCR testing of CSF can help shorten hospitalization, and avoid the unnecessary use of antibiotics.
