In April 1981, an outbreak of hepatitis A occurred among state legislators in Tennessee. Although the number of cases was small, we traced the source to a food handler who served cold meats and cheese. This investigation demonstrates the value of rapid serologic testing using a radioimmunoassay technique and matched case-control analysis to identify small foodborne outbreaks of hepatitis A.
1981年4月，田纳西州的州议员中爆发了甲型肝炎疫情。尽管病例数量不多，但我们追踪到源头是一名提供冷肉和奶酪的食品处理人员。这项调查证明了使用放射免疫测定技术进行快速血清学检测以及配对病例对照分析在识别小规模食源性甲型肝炎疫情方面的价值。
