Abstract
An outbreak of aseptic meningitis (AM) occurred in Jinzhai County in Anhui province from April to July in 2005. Totally, 97 children aged 3-15 years were hospitalized. To identify the etiologic agent, 77 cerebrospinal fluid specimens (CSF) and 5 fecal specimens were collected from the patients and cultured by human rhabdomyosarcoma (RD) cell line. Thirty isolates of human echovirus 6 (E6) from 27 CSF and 3 fecal specimens were confirmed by neutralization assay and sequencing analysis of the VP1 gene. The homology of VP1 gene among Anhui isolates was 99.7-100.0% and it indicated that this AM outbreak probable caused by a single transmission link of E6. Phylogenetic analysis based on all the available complete VP1 sequences indicated that E6 could be divided into clusters A, B, and C with at least 15% diversity between clusters and the C cluster could be further divided into C1, C2, C3, and C4. The Anhui isolates most resembled a 2005 strain from Russia (25465 Tambov) and belong to C4. This is the first report that E6 was responsible for an outbreak of AM in China. J. Med.
