Rowan County Public Health in North Carolina is investigating a confirmed tuberculosis case involving a person at the Rowan-Salisbury School System and is offering free testing to students and staff identified as significantly exposed, the county said in a news release posted Sept. 28. All close contacts have already been notified by either the health department or the school district.
For most families in the district, officials say no action is needed. Anyone who was exposed will be contacted directly with testing instructions, and the county stressed that TB develops over weeks to months and is curable with medication.
The county has not said whether the person is a student or staff member, which school is involved, or how many contacts are being tested. Those gaps may leave parents with questions, and the county's TB line is the main place to get answers.
Details the County Has Confirmed
Rowan County Public Health said it is working with the North Carolina Department of Health and Human Services Division of Public Health and school officials to find everyone who may have had significant exposure. Those who test positive will receive further evaluation and instructions, the county said.
"We understand that learning about a communicable disease exposure can be concerning for students, families and staff," said Alyssa Harris, Rowan County Public Health director. "Addressing communicable disease is a core and routine responsibility of public health," she added, according to the Salisbury Post.
Health officials also said TB "is not immediately life-threatening or an emergency," WBTV reported. The county asked residents to avoid emergency departments solely for TB testing unless they have severe symptoms. Residents with questions can call the Rowan County Public Health Tuberculosis Line at 704-216-8771.
Contact Testing, Step by Step
TB spreads through the air when a person with active TB disease of the lungs or throat coughs, speaks, or sings, according to the CDC. The germs can stay in the air for several hours, depending on the environment. That is why health departments focus on people who spent extended time sharing air with a sick person, rather than everyone in a building.
Close contacts are usually offered one of two tests. A blood test measures the immune system's response to TB germs. A skin test involves a small injection under the skin, with a follow-up visit two to three days later to check for a reaction.
Timing matters. Because it can take several weeks after exposure for a test to turn positive, the CDC generally advises retesting people who first test negative about eight to 10 weeks after their last exposure. Families who receive instructions from the county should follow the schedule they are given, even if a first test is negative.
A positive result does not mean a person is sick or contagious. Many people have inactive, or latent, TB, meaning the germs are in the body but cause no symptoms and cannot spread to others. The CDC says that without treatment, 1 in 10 people with inactive TB will develop active TB disease, which is why those who test positive are evaluated further and often offered medication.
Symptoms Families Should Know
Active TB disease most often affects the lungs. Symptoms include a cough lasting three weeks or longer, chest pain, coughing up blood, weakness or fatigue, weight loss, loss of appetite, chills, fever, and night sweats, according to the CDC.
People with weakened immune systems, including those with HIV, diabetes, or cancer, face a higher risk of developing TB disease after infection. Recent close contact with someone who has active TB is also a key risk factor. Anyone in the district with a lasting cough or other symptoms should contact a doctor and mention the school exposure, even if they have not been contacted by the county.
Parents can help by keeping a simple record of any symptoms, when they started, and any notice the family received from the county or school. That information makes a doctor's visit faster and more useful.
TB is treatable and curable, but treatment takes months and must be completed. People who stop early can become sick again or develop drug-resistant TB. Testing offered through the county is free for those identified as exposed, which removes one common barrier for families without insurance.
A Local Case Amid Elevated National Numbers
Health departments handle single school-linked TB cases routinely, and one case does not signal an outbreak. Nationally, the CDC reported 10,260 TB cases in provisional data for 2025, a slight drop from 2024 but still above pre-pandemic levels, as MedicalDaily noted in its coverage of U.S. tuberculosis trends. The CDC estimates that up to 13 million people in the United States have inactive TB.
The county has not said when testing will be completed or whether it will release results. Privacy rules limit what health departments share about individual patients, but a summary of how many contacts were tested and how many tested positive would help parents understand the scope.
The next steps are testing for those identified as close contacts and follow-up care for anyone who tests positive. Families who have not been contacted can continue normal routines, watch for symptoms, and call the county's TB line with questions. The health department remains the main source for updates.
