  • a Samples from ERs were taken from 1993 to 1995; samples from hospitals were taken from 1985 to 1987.

  • b Indeterminates and low positives with an optical density differential between 0.07 and 0.31 (see text).

  • c Differences in percent positivity among different ERs and between rotavirus-negative and -positive samples were not significant (P > 0.5 by the chi-square or two-tailed Fisher’s exact test).
