Outbreaks of hepatitis A (HA) attributable to water contamination have been reported; however, the impact of water supply characteristics on the endemic rates of HA has not been quantified. This study did not detect any statistically significant associations between endemic HA rates and water supply characteristics. Because of the sample size, this finding suggests that the total variation of HA rates attributable to water supply characteristics is probably less than 8 per cent of the annual reported cases of HA in the United States.
已有报告称甲型肝炎（HA）疫情是由水污染所致；然而，供水特征对甲型肝炎流行率的影响尚未得到量化。本研究未发现甲型肝炎流行率与供水特征之间存在任何具有统计学意义的关联。鉴于样本量，这一发现表明，归因于供水特征的甲型肝炎流行率的总变化可能不到美国每年报告的甲型肝炎病例数的8%。
