Tulsa, OK — Education officials and health experts have confirmed a case of Tuberculosis (TB) at McLain High School. The Tulsa Health Department (THD) informed Tulsa Public Schools of the diagnosis on July 22, 2025. The case was initially identified sometime between March 1 and the end of the school year on May 23, 2025. The health department became aware of the case at the end of June and has since launched a comprehensive investigation.
The THD’s investigation involves determining where the infected individual has been and identifying those who may have come into close contact. The process begins with locating the person’s residence and testing household members. It also includes examining the individual’s whereabouts at school, work, church, or other community locations during the infectious period.
During the investigation, health officials will test individuals who may have been exposed. This includes staff, students, and other close contacts. The primary goal is to identify any potentially infected individuals early to prevent further spread.
The infected person was likely contagious during the period from early March through late May, but the exact timeframe is being confirmed through contact tracing and testing.
TB is a bacterial infection that mainly affects the lungs but can also impact other parts of the body. If untreated, it may cause severe health complications and damage key organs. The infection spreads through airborne particles when an infected person coughs, sneezes, or talks.
Individuals exposed to TB may develop symptoms within three months after exposure. Common signs of TB include:
Recognizing these symptoms early is vital since prompt treatment can prevent serious health outcomes. However, TB can remain latent and asymptomatic in some cases, making screening essential for exposed persons.
Officials have emphasized that there is no ongoing risk of further exposure in the school environment. The THD has clarified that no additional cleaning or disinfection of McLain High School is necessary, as TB bacteria do not survive long outside the human body.
The department reassures that it is safe for students and staff to return to school next month. They are confident that current measures will prevent further cases or transmission.
Furthermore, Tulsa typically reports approximately 69 TB cases annually. On a national level, there were around 10,347 cases last year. In Oklahoma, the previous year’s total was 64 cases.
To assist those potentially exposed, the THD will hold free TB testing sessions on July 23 and July 25 at the North Regional Health and Wellness Center in Tulsa. The testing hours are from 9:00 a.m. to 4:00 p.m.. Results are expected within a few days, depending on the testing date.
Community members who suspect they may have been exposed or need more information are encouraged to contact the THD directly at 918-582-9355. The health department recommends that anyone with symptoms or recent exposure seek testing and medical consultation.
Tulsa sees around 69 TB cases each year, reflecting a relatively stable rate within the state. Nationally, TB remains a public health concern with over 10,000 cases reported annually. In Oklahoma, the year prior saw 64 cases, indicating a consistent presence of the disease. Public health officials continue to monitor and manage TB through screening, treatment programs, and education efforts to keep the community safe.
Individuals are advised to stay informed about TB symptoms and adhere to medical guidance if they believe they may have been exposed. Early detection and treatment remain the most effective strategies to control the spread of tuberculosis in the community.
