In September 2019, after a reported death due to acute diarrheal disease in Shahpur village, Panchkula district, Haryana state, India, we conducted an outbreak investigation to identify the etiological agent, estimate the burden of disease, and make recommendations to prevent future outbreaks. The suspected cholera case was a resident of Shahpur huts, ≥1 year of age having ≥3 loose stools within a 24-h period between September 1 and 28, 2019 and a laboratory-confirmed cholera case, whose stool specimen tested positive for Vibrio cholerae. We identified 196 suspected cholera cases with a median age of 18 years (range: 1-65 years); 54% (106) being female. The overall attack rate was 8% (196/2,602), and the case fatality rate was 1% (2/196). Tested samples of water from tanks (n = 6), sewage effluent (n = 2), and 22% (4/18) of stool specimens collected from suspected cases were positive for V. cholerae. Strengthening surveillance, improving water, and sanitation systems are recommended to prevent future cholera outbreaks.
2019 年 9 月，印度哈里亚纳邦潘奇库拉区沙普尔村报告一起急性腹泻病死亡病例后，我们开展了一次暴发调查，以确定病因、估计疾病负担，并提出建议以防止未来暴发。疑似霍乱病例为沙普尔棚户居民，年龄≥1 岁，在 2019 年 9 月 1 日至 28 日期间的 24 小时内出现≥3 次稀便，实验室确诊霍乱病例的粪便标本检测出霍乱弧菌阳性。我们共发现 196 例疑似霍乱病例，中位年龄为 18 岁（范围：1-65 岁）；54%（106 例）为女性。总发病率为 8%（196/2602），病死率为 1%（2/196）。对水箱水（n=6）、污水（n=2）样本以及从 18 例疑似病例中采集的 22%（4/18）的粪便样本进行检测，结果均显示霍乱弧菌阳性。建议加强监测，改善供水和卫生系统，以防止未来发生霍乱暴发。
