OBJECTIVES: Enteroviruses (EVs) are the most common cause of aseptic viral meningitis. In some cases, they can cause severe meningoencephalitis and acute flaccid paralysis - an association with some virulent serotypes. The objectives were to describe the epidemiological situation of EV meningitis in children in South Moravia, to elucidate the etiology including the incidence of virulent serotypes and to evaluate the clinical presentation.
MATERIAL AND METHODS: A total of 88 children with EV meningitis were prospectively evaluated. In case of aseptic inflammation in the cerebrospinal fluid, EV was detected using real-time PCR. Genotyping was performed in 56 samples using repeated one-step PCR and partial sequencing on a genetic analyzer in the National Reference Laboratory for Enteroviruses in Prague.
RESULTS: The patients' age range was 3-17 years; there were more boys than girls. Two epidemics occurred, one involving 17 Roma children and the other involving 8 swimming pool visitors. The most common symptoms were headache, fever and stiff neck. The most frequently (59%) detected agent was Echovirus 30 identified as the cause of the epidemics. In one boy, EV 71 (virulent serotype) was found. The clinical course did not vary from that in other serotypes. All 88 children recovered without complications.
CONCLUSIONS: EVs are an important part of the differential diagnosis of neuroinfections, although most infections are benign aseptic meningitis. The clinical presentation did not vary between infections with various serotypes. Higher incidence rates of virulent serotypes were not reported. Echovirus 30 was detected most frequently and was repeatedly identified as the cause of epidemics throughout the Czech Republic.
