A previous study examined temporal patterns of respiratory hospitalizations and PM10levels in Utah County, Utah, between April 1985 and February 1988. Statistically significant correlations were found between monthly PM1 0 levels and pediatric admissions for pneumoniapleurisy and bronchitis-asthma. We performed an expanded analysis and found strong, coherent evidence that the major determinant of elevated levels of pediatric respiratory hospitalizations was biological rather than chemical. Respiratory syncytial virus (RSV) activity was the single explanatory factor that consistently accounted for a statistically significant portion of the observed variations of pediatric respiratory hospitalizations. No coherent evidence of residual statistical associations between PM10 levels and hospitalizations was found for any age group or respiratory illnes.
