Capitola 海滩因大肠杆菌 O157 关闭，9 名儿童感染
位于美国加州圣克鲁斯县 Capitola 市的 Capitola 海滩已被临时关闭。圣克鲁斯县与 Capitola 市 11 月 10 日联合宣布，湾区 9 名儿童感染大肠杆菌 O157，暴露很可能与这片海滩及周边水域有关，海滩即日起关闭，公共卫生部门正在调查污染来源。截至 11 月 12 日，关闭仍在持续，重开时间尚未公布。
圣克鲁斯县公共卫生局通报，县方共接到 9 例大肠杆菌 O157 感染报告，患者全部为儿童，其中 4 人是圣克鲁斯县居民，另 5 人来自湾区其他县。县方表示，9 例病例彼此关联，提示存在共同来源或相关暴露，全部暴露很可能发生在 Capitola 海滩或周边水域，但污染源头目前仍未查明。
圣克鲁斯县卫生官员 Lisa Hernandez 11 日向媒体说明，其中两名儿童曾住院治疗，一名儿童出现溶血性尿毒综合征并发症，目前 9 名儿童均已康复，无人死亡。
县环境健康部门已在 Soquel Creek 与 Capitola 海滩周边四处地点采样，分别是 Nob Hill 附近的上游水域、海滩防波堤、Soquel Creek 潟湖，以及溪水注入 Monterey Bay 的水闸口，后续还将开展更多大肠杆菌检测。据县卫生官员介绍，土壤、水体等样本已送交联邦疾病控制与预防中心（CDC）协助检测。圣克鲁斯县与 Capitola 市正与加州公共卫生局（CDPH）和 CDC 密切协调。
县方提醒居民与游客：不要进入关闭区域内的水域，不要饮用溪流、潟湖等天然水体的生水，有开放性伤口时避免游泳，接触天然水体后应淋浴，宠物应远离可能受污染的水体并饮用清洁水，并留意关闭告示与卫生提示。Capitola 市表示，海滩旁的 Esplanade 商圈照常开放。
大肠杆菌 O157 可引发严重胃肠道疾病，症状包括可能带血的腹泻、腹部绞痛和呕吐，部分感染可发展为严重并发症，幼儿风险尤其高；出现相关症状应及时就医，出现血性腹泻或脱水迹象应尽快求诊。县方表示，海滩将持续关闭至进一步评估完成，条件允许重开时将通知公众，县环境健康局在其水质监测页面更新本地水质信息。卫生部门同时说明，此次疫情与 San Luis Obispo 县南瓜农场的大肠杆菌疫情分别调查，暂未发现两起疫情有关联。
Capitola Beach Closed Over E. coli O157 Outbreak That Sickened Nine Children
Capitola Beach, in the city of Capitola in Santa Cruz County, California, has been temporarily closed. Santa Cruz County and the City of Capitola jointly announced on November 10 that the beach would close after nine Bay Area children were infected with E. coli O157, with exposures believed to be linked to the beach and surrounding waterways, as public health officials investigate the source. As of November 12, the closure remained in effect and no reopening date had been announced.
The Santa Cruz County Public Health Division said it has been notified of nine cases of E. coli O157 infection, all of them children: four are Santa Cruz County residents and five are residents of other Bay Area counties. All nine cases are linked, indicating a common source or related exposures, and officials determined that all exposures likely occurred at Capitola Beach or in surrounding waterways. The source of the outbreak remains unknown.
Santa Cruz County Health Officer Lisa Hernandez told reporters on November 11 that two of the children had been hospitalized and one developed hemolytic uremic syndrome, a serious complication. All nine children have since recovered, and no deaths were reported.
Environmental sampling has been conducted at four locations in and around Soquel Creek and Capitola Beach: an upstream location near Nob Hill, the jetty, Soquel Creek Lagoon and the flume where the creek's water enters Monterey Bay, and additional E. coli testing is planned. According to the county health officer, soil, water and other samples have been submitted to the Centers for Disease Control and Prevention (CDC) for testing. The County and City are coordinating closely with the California Department of Public Health (CDPH) and the CDC.
Officials advise residents and visitors to stay out of the water within the posted closure area, avoid drinking untreated water from creeks, lagoons or other natural waterbodies, avoid swimming with open wounds and shower after contact with natural waterways, keep pets out of potentially contaminated water and give them clean drinking water, and follow posted closure signs and public health advisories. The City of Capitola said the Esplanade, the shop-lined area beside the beach, remains open.
E. coli O157 can cause severe gastrointestinal illness, including diarrhea that may be bloody, abdominal cramps and vomiting, and some infections can lead to serious complications, particularly among young children. Anyone experiencing concerning symptoms should contact a health care provider, and people with bloody diarrhea or signs of dehydration should seek prompt medical attention. The beach will remain closed pending further assessment, and the public will be notified when conditions allow it to reopen. Health officials said this outbreak is being investigated separately from the E. coli outbreak tied to a pumpkin farm in San Luis Obispo County, and no connection between the two has been found.
