俄亥俄州志贺菌病例10月26日达383例 逼近去年全年总数
俄亥俄州卫生厅数据显示，截至10月26日，该州2026年已报告志贺菌病（shigellosis）病例383例，逼近2025年全年的395例；10月以来新增26例，而10月8日之前当月仅报告10例。病例以富兰克林县最多，达122例，其次是凯霍加县45例、萨米特县28例、汉密尔顿县23例。
今年病例中，男性258例、女性125例，中位年龄39岁，住院118例、占30.8%。志贺菌通过粪口途径、性接触及受污染的食物和水传播，可引发腹泻、发热和胃痉挛，多数人在五到七天内康复。
卫生官员日益担忧耐药菌株：美国疾病控制与预防中心（CDC）4月报告显示，广泛耐药志贺菌占比从2011年的0%升至2023年的8.5%，常规口服抗生素对其效果有限。CDC估算志贺菌病每年在全美造成约45万例感染，并建议勤洗手、患病时留在家中、症状严重时及时就医；确诊者及其伴侣在症状结束后至少两周内应避免性行为。
Ohio Shigella Cases Reach 383 as of October 26, Approaching Last Year's Full-Year Total of 395
Ohio has reported 383 cases of shigellosis in 2026 as of October 26, according to the Ohio Department of Health, approaching the 395 cases reported in all of 2025. The state reported 26 new cases in October, compared with 10 reported by October 8. Franklin County has reported the most cases with 122, followed by Cuyahoga County (45), Summit County (28) and Hamilton County (23).
Among this year's Ohio cases, 258 were male and 125 female, the median age is 39, and 118 patients — 30.8 percent — were hospitalized. Shigella bacteria cause shigellosis through fecal-oral transmission, sexual contact and contaminated food or water, triggering diarrhea, fever and stomach cramps; most people recover within five to seven days without antibiotics.
Health officials are increasingly concerned about drug-resistant strains that are becoming harder to treat. An April CDC report found extensively drug-resistant Shigella made up 8.5 percent of samples in 2023, up from 0 percent in 2011. The CDC estimates shigellosis causes about 450,000 infections in the United States each year and recommends washing hands properly, staying home when sick and seeking medical care if symptoms become severe; people diagnosed with shigellosis should not have sex for at least two weeks after symptoms end.
