A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem

BACKGROUND: Acute enterovirus (EV) meningitis is a major cause of hospitalization among adults and children. It is caused by multiple EV genotypes assigned to 4 species (EV-A, EV-B, EV-C, and EV-D).

METHODS: We determined viral loads in the cerebrospinal fluid (CSF) of 156 patients of all ages with EV meningitis during a 5-year observational prospective study. The virus strains were genotyped, and their time origin was determined with Bayesian phylogenetic methods.

RESULTS: The CSF viral loads ranged between 3.4 and 7.5 log10 copies/mL (median, 4.9 log10 copies/mL). They were higher in neonates than in infants and children (P = .02) but were comparable in adults. Viral loads were associated with EV genotypes (P < .001). The EV strains were identified in 152 of 156 patients and assigned to 23 genotypes within the EV-A and EV-B species. The most frequent genotypes, echoviruses 6 and 30, were associated with different viral loads (P < .001). The highest viral loads were in meningitis cases caused by coxsackievirus A9, B4, and B5 genotypes. Most patients infected by a same genotype were infected by a major virus variant of recent emergence.

CONCLUSIONS: The variations in CSF viral loads in patients at the onset of EV meningitis are related to genotypic differences in the virus strains involved.
