Court documents filed in Colorado's federal lawsuit against the GEO Group and the Department of Homeland Security show that state and county health officials spent more than two months trying and failing to gain access to an active tuberculosis case inside the Aurora immigration detention center before turning to the courts.
The filings, reviewed and reported by Colorado Public Radio, lay out a sequence of unanswered emails, missed deadlines, and referrals to lawyers. State health officials were first told of the case in mid June. More than two months later, public health investigators still do not know where the original patient is, whether additional people were infected, or who was exposed.
For families in Adams County and the Denver metro, that is the concrete stake. A detention facility is not a sealed box. Staff, contractors, attorneys, and visitors move in and out daily. When a communicable airborne disease is identified inside one, and contact tracing cannot begin, the people who share a school, a workplace, or a household with those workers are the ones left uncounted.
A Public Health Investigation That Never Got Inside
Adams County health officials began by writing to the detention center's warden. According to the court filings, those requests mostly went unanswered. Three days later, the county issued a formal public health order seeking exposure information, the medical records of the person with confirmed tuberculosis, and a list of exposed staff and detainees within a day. That deadline passed.
The state escalated on July 14, when Colorado Department of Public Health and Environment chief Jill Hunsaker Ryan sent the warden and GEO's health administrator a letter giving them three days to provide access and records, citing a state statute she said granted that authority. Two more days passed before a GEO attorney responded, saying the documents were in federal rather than company possession and that he should be contacted directly going forward.
Attempts to arrange a call involving Gov. Jared Polis were declined. GEO's attorney replied that the facility's warden was unavailable and pointed to a statement from the Department of Homeland Security saying the facility had no confirmed tuberculosis cases. DHS is not a public health agency, and county and state officials were still trying to manage a reported infectious disease.
Polis spokesman Eric Maruyama told Colorado Public Radio that the state made numerous attempts to reach GEO officials and got back little beyond what looked like a response written by lawyers. He added that the dispute did not need to reach court. "This could all be resolved with a normal meeting and information exchange," he said. Colorado Public Radio reported that the state attorney general's office filed suit 33 days later. GEO and ICE did not respond to questions from the station.
Contact Tracing Only Works if Investigators Can Reach Contacts
Tuberculosis spreads through the air when a person with active disease in the lungs coughs, sneezes, or speaks. It is not spread by touching surfaces or sharing food. Transmission generally requires prolonged shared air, which makes crowded congregate settings the classic high risk environment.
The standard response is a contact investigation. Health officials identify who shared air with the patient, test them, and treat anyone who converts. Most people who become infected develop latent tuberculosis, meaning the bacteria are present but dormant, causing no symptoms and posing no transmission risk. A portion of those will progress to active disease later, sometimes years later, and treatment of latent infection is what prevents that.
None of that machinery has been able to start here. Without a list of exposed people, there is nobody to test. Without medical records, investigators cannot confirm whether the original case was drug-resistant, which would change both the treatment plan and the urgency. Colorado Public Radio reported that the immediate crisis appears to have passed or moved beyond where public health experts can see it, which is not the same as being resolved.
Tuberculosis Has Not Left the United States
The disease remains a live domestic problem. National surveillance data from the Centers for Disease Control and Prevention recorded 10,388 tuberculosis cases in 2024, an incidence rate of 3.1 per 100,000 people. That was a 7.9 percent increase in cases over 2023 and the fourth consecutive annual rise, following nearly three decades of steady decline.
Provisional weekly counts published through the National Notifiable Diseases Surveillance System show 4,576 cases among U.S. residents through the week ending Aug. 1, 2026, with 46 reported in Colorado. Over the same stretch of the previous year, the provisional national count stood at 5,754. Provisional figures lag substantially and are revised as reports arrive, so neither number should be read as a final annual comparison.
Risk is not evenly distributed. People with weakened immune systems, including those with HIV or diabetes or on immunosuppressive medication, face the highest chance of latent infection progressing to active disease. So do young children and older adults. Crowded settings with limited ventilation raise exposure odds for everyone inside.
The Court Fight Is Now About the Next Outbreak
The litigation continues in U.S. District Court in Colorado. Whatever it produces is unlikely to resolve the original case. What the state is seeking is a declaration that public health officials have a right to records and facility access during a public health event, which would matter for the next one. Detention numbers in the state are rising, and a new GEO facility has been proposed in Hudson.
Residents worried about exposure should know that ordinary community contact does not transmit tuberculosis. People who believe they had prolonged close contact with someone diagnosed with active disease, and anyone with a cough lasting more than three weeks, unexplained weight loss, night sweats, or fever, should contact a clinician or their county
Key Questions Answered
What is genuinely new? Court filings detail the specific sequence of unanswered requests, missed deadlines, and legal referrals that preceded Colorado's lawsuit, including declined attempts to arrange a call with the governor.
Is there an active tuberculosis outbreak in Aurora? That is unknown, which is the core problem. Officials were told of one active case in mid June and have not been able to determine whether others exist.
Can tuberculosis spread outside a detention facility? Yes, in principle, through staff, contractors, and visitors who share air inside and then return to the community. No community spread has been confirmed here.
How does tuberculosis spread? Through the air over prolonged close contact. It is not spread by surfaces, food, or brief passing contact.
What symptoms should residents watch for? A cough lasting more than three weeks, coughing up blood, chest pain, fever, night sweats, and unexplained weight loss warrant medical evaluation.
Who is most at risk? People with weakened immune systems, young children, older adults, and anyone with prolonged exposure in a crowded, poorly ventilated setting.
What happens next? The case continues in federal court, where Colorado is seeking a ruling on access rights for future public health events rather than a remedy for this one.
