Health officials in Garfield County have contacted nearly 800 people as part of a tuberculosis investigation tied to Enid Public Schools, isolating at least one affected student and launching a testing push that has touched much of the district community. The scale of the contact tracing effort, confirmed in a report published Thursday, underscores how seriously local and state health authorities are treating the case even as basic details — including exactly how many students are infected — remain unsettled.
According to The Oklahoman, a student at Enid Public Schools tested positive for tuberculosis, and that student has been isolated to prevent airborne spread of the disease. The outlet reported that nearly 800 people were contacted on Oct. 19 as officials worked to identify staff and fellow students who may have been exposed. Other outlets have described the situation differently: Enid News & Eagle reported that two high school students were identified with an active case of tuberculosis, while News 9 stated plainly that the exact number of confirmed cases has not been released. KOCO-TV's May 1, 2025 report concerned an earlier Enid High School exposure involving an active case, separate from the October 2026 investigation.
Contact Tracing Underway Across the District
The Garfield County Health Department and Oklahoma State Department of Health are conducting contact tracing, per the same News 9 report, working to identify people who may have been exposed to tuberculosis and determine whether additional testing or follow-up is needed. Individuals identified as contacts through that process are tested to determine whether further monitoring is recommended, the station reported. The Garfield County Health Department has also encouraged parents and guardians to complete testing registration through a link provided by the school.
The diagnosed students were Enid High School students. Superintendent Dudley Darrow told KOCO in May 2025, in connection with an earlier Enid exposure, that the district was working with the health department, saying, “we're working with the health department on that.” KOCO also reported that Enid Public Schools continued its regular operations while contact tracing began during the May 2025 exposure investigation.
How Tuberculosis Spreads — and Why Officials Say Risk Is Limited
Tuberculosis can spread through the air when someone with active disease coughs, speaks or sings, per News 9's reporting. Frequent or prolonged indoor exposure is more concerning than short, casual interactions, the San Diego County News Center reported. Amy Hill of the Oklahoma State Department of Health told KOCO that “it is a bacteria that floats in the air. You have to be in small, tight congregate settings for a long period of time to have exposure.” Dr. Sumit Nanda, immediate past president of the Oklahoma State Medical Association, said tuberculosis spreads through inhalation of droplets and recommended testing for anyone who believes they may have been exposed.
Doctors describe tuberculosis as treatable, though the course is not short. Treatment includes antibiotics that kill the bacterium and typically lasts six months or longer, and patients undergoing treatment should not skip doses. Symptoms can include chronic cough, fevers, chills, night sweats and weight loss. Nanda noted that tuberculosis has had a worldwide presence for hundreds or perhaps thousands of years and remains more endemic in developing countries, even as U.S. cases had been increasing since the pandemic, rising 8% in 2024 to their highest level since 2011.
How This Compares to Oklahoma's Usual Case Numbers
Oklahoma typically sees between 60 and 70 tuberculosis cases a year, according to KLAW, which reported the state recorded 64 cases and 1,486 latent cases in 2024. The station's report also noted that nine cases had been logged in Oklahoma as of late January 2025. KOCO separately reported that last year's count of 64 cases is considered average by the state health department, even as national figures have climbed — CDC data cited by the station showed an 8% rise in tuberculosis cases in 2024 compared with the prior year, reaching the highest levels since 2011.
Garfield County itself recorded 14 tuberculosis cases in 2025, per News 9's reporting, a notable share of the state's annual total concentrated in one county. Similar school-based exposures have surfaced elsewhere this year: in San Diego County, health officials this week reported a tuberculosis exposure at Southwest High School spanning June 2025 through March 2026, according to the San Diego County News Center. That case marked the fourth person associated with the school diagnosed with active TB within two years, though county officials noted nearly 90% of students exposed to earlier cases there tested negative for active disease. San Diego County logged 265 active TB cases in 2025 overall, far more than Oklahoma's statewide count, underscoring how case rates vary widely by region even as the underlying disease and transmission risks remain the same.
