San Diego县通报Southwest High School结核暴露：两年内第4例 11月第一周校内免费检测
位于加州圣迭戈县 San Diego 市的 Southwest High School 出现结核病暴露事件。圣迭戈县政府10月21日通报，县卫生官员正与 Sweetwater Union High School District 合作，通知可能在2025年6月23日至2026年3月6日期间在该校接触过一名结核病活动期患者的师生。
县政府表示，已直接联系风险最高的人群，并将于11月第一周在校内为全体在校学生与教职员工提供免费结核血液检测，流动车辆也将进驻校园拍摄胸部X光片。已经离校的学生正陆续收到通知，可于12月4日下午1时30分至6时在该校南停车场（South Lot）接受免费检测。
县政府表示，这是近两年内与该校关联的第4名活动性结核病确诊者；调查人员正在核查新病例与此前病例之间的关联，新病例的基因检测尚待完成。此前病例中有两份样本经基因测序为不同菌株，过往检测未显示这些病例之间存在基因关联。县公共卫生官 Sayone Thihalolipavan 表示，把检测带到学校至关重要，以便发现潜在感染者、阻断可能的传播。
县政府公布的数据显示，圣迭戈县活动性结核病例数由2020年的193例逐年升至2025年的265例；全县估计约有17.5万人携带潜伏性结核感染。县结核病控制项目电话为 619-692-8621。
San Diego County Reports Tuberculosis Exposure at Southwest High School: Fourth Case in Two Years, Free Testing in Early November
San Diego County officials said on October 21 that county health officials are working with the Sweetwater Union High School District to notify students and staff about a tuberculosis exposure at Southwest High School in San Diego, in San Diego County, California. The possible exposure period ran from June 23, 2025, to March 6, 2026.
The county said it has contacted the people at highest risk and will offer free TB blood testing at the school for all current students and staff during the first week of November, with a mobile vehicle on campus to take chest X-rays. Former students are being notified and can receive free testing at the school on December 4, 2026, from 1:30 p.m. to 6 p.m. in the South Lot student parking area.
This is the fourth person associated with Southwest High School diagnosed with active TB within the past two years, the county said. Investigators are exploring connections between the new case and earlier cases, and genetic testing of the newest case is pending; two samples from earlier cases were genetically sequenced and found to be different strains, and previous testing did not show a genetic link between those cases. 'Bringing testing to the school is crucial to identify any latent TB infections and stop potential spread given the high number of cases in such a short timespan,' said Sayone Thihalolipavan, M.D., MPH, the County Public Health Officer.
The county reported annual active TB cases of 193 in 2020, rising to 265 in 2025, and estimated that about 175,000 people in San Diego County have latent TB infection. The County TB Control Program can be reached at 619-692-8621.
