This study assessed the impact in Georgia of a nationwide salmonellosis outbreak caused by ice cream products and the effectiveness of the subsequent warning against eating the implicated products.
A telephone survey of 250 randomly selected Georgia customers of the ice cream producer was conducted 13 to 17 days after the warning.
Respondents from 179 households representing 628 persons were interviewed. The median date of first hearing the warning was 5 days after it was issued, and 16 respondents (9%) had not heard it. Among those who had heard the warning, 42 (26%) did not initially believe the products were unsafe. In 22 (31%) of the 72 households that had the implicated ice cream when the respondent heard the warning, someone subsequently ate the ice cream. Diarrhea was reported in 26% (121/463) of persons who had eaten the products but in only 5% (8/152) who had not (odds ratio [controlling for household clustering] = 3.8; 95% confidence interval = 2.0, 7.5). We estimate this outbreak caused 11,000 cases of diarrhea in Georgia, 1760 (16%) with exposure after the warning.
A large outbreak occurred in Georgia, much of which might have been prevented by a more timely and convincing warning.
本研究评估了格鲁吉亚全国范围内由冰淇淋产品引发的沙门氏菌病暴发的影响，以及随后针对食用受牵连产品发出警告的有效性。
在发出警告后的13至17天，对冰淇淋生产商的250名随机挑选的格鲁吉亚客户进行了电话调查。
对来自179户家庭、代表628人的受访者进行了访谈。首次听到警告的中位日期是在警告发布后的5天，16名受访者（9%）没有听到该警告。在那些听到警告的人中，42人（26%）最初不相信这些产品不安全。在受访者听到警告时家中有受牵连冰淇淋的72户家庭中，有22户（31%）家中有人随后食用了该冰淇淋。报告称，食用了这些产品的人中有26%（121/463）出现腹泻，而未食用的人中只有5%（8/152）出现腹泻（比值比[控制家庭聚集因素]=3.8；95%置信区间=2.0, 7.5）。我们估计，这次暴发在格鲁吉亚导致了11000例腹泻病例，其中1760例（16%）是在警告发出后接触感染源的。
格鲁吉亚发生了大规模暴发，若发出更及时、更有说服力的警告，很大一部分病例可能会得到预防。
