Health officials in New Jersey are investigating a potential tuberculosis exposure linked to a student at Tri-State High School in Hudson County, where contact tracing has identified at least 12 close contacts since May 20, 2026, according to the New Jersey Department of Health (NJDOH). The student, identified only as a 17-year-old sophomore, tested positive for *Mycobacterium tuberculosis* after presenting with persistent cough and fatigue, prompting school-wide notifications and prophylactic treatment offers.
Identified Exposure and School Response
As of June 4, 2026, the NJDOH confirmed that the Hudson County Department of Health is leading contact investigations at Tri-State High School (located in Bayonne, NJ), where the index case was diagnosed. The school, serving approximately 1,200 students across grades 9–12, has suspended in-person classes for grades 9 and 10 pending further air-quality assessments and environmental sampling for *M. tuberculosis* bacteria, per a June 3 emergency order from Hudson County Health Director Dr. Elena Vasquez.
The NJDOH reported that the student’s infection was classified as latent TB (non-contagious) but that exposure risks were elevated due to prolonged close contact in shared spaces, including the school’s cafeteria, science labs, and band room, where the student participated in activities between May 10 and May 20. Health officials emphasized that active TB (contagious) was not confirmed in the student, though routine testing revealed the latent form, which requires treatment to prevent progression.
In a statement, Hudson County Superintendent Dr. Richard Chen acknowledged the “unexpected nature” of the finding but noted that the school’s HVAC systems had undergone quarterly inspections in April 2026, with no prior TB-related deficiencies cited. “We are following NJDOH protocols to the letter,” Chen said, adding that all identified contacts—including students, staff, and faculty—had been offered isoniazid preventive therapy (IPT) and referred for follow-up chest X-rays.
Contact Tracing and Public Health Measures
Contact tracing efforts, conducted by the Hudson County Health Department in collaboration with the New Jersey Medical Examiner and Health Authority, have prioritized individuals with ≥8 hours of cumulative exposure to the student during the May 10–20 infectious period.
- 12 confirmed close contacts (all asymptomatic at last check-in).
- 45 additional individuals classified as “casual contacts” (≤4 hours exposure) and monitored for symptoms.
- Zero secondary cases identified to date, though follow-up testing continues.
Health officials stressed that TB transmission in schools is rare but requires rigorous response due to the highly contagious nature of active TB. The NJDOH’s 2025 TB Control Plan mandates that schools report suspected exposures within 48 hours, a timeline met in this case. Dr. Vasquez told reporters that the Bayonne school district’s compliance with notification protocols had been “exemplary,” though she declined to speculate on whether the exposure might have been prevented by earlier symptom reporting.
For contacts who decline IPT, the NJDOH is providing monthly symptom screening and quarterly chest X-rays for 12 months, aligned with CDC guidelines for latent TB exposure. The department also issued a public advisory on June 2, urging residents with cough lasting ≥3 weeks, unexplained weight loss, or night sweats to seek testing at Hudson County’s TB Clinic or any primary care provider.

Regulatory and Political Scrutiny
The incident has drawn attention from New Jersey Governor Phil Murphy, who cited it as a reminder of the “resurgent threat of TB” in the U.S., despite a 90% decline in cases since 1990. In a June 3 press briefing, Murphy’s office noted that New Jersey’s TB rate (2.1 cases per 100,000 in 2025) remains below the national average (2.7), but warned of “silent hotspots” in urban areas with high immigrant populations and homeless shelters.
Criticism has also focused on funding for TB programs. The New Jersey Chapter of the American Lung Association released a statement on June 4 calling for $5 million in additional state funding for contact tracing and ventilation upgrades in schools, citing outdated HVAC systems in 30% of Hudson County public schools. The NJDOH, however, defended its current budget, stating that federal CDC grants cover 80% of TB control costs in the state.
Senator Cory Booker (D-NJ), whose district includes Hudson County, announced plans to introduce legislation requiring annual TB risk assessments in all New Jersey schools.
“No child should fear TB in their classroom. We must modernize our public health infrastructure to catch exposures like this before they spread. New Jersey must lead on this.”
Senator Cory Booker
The New Jersey Education Association (NJEA) has urged schools to mandate TB screening for all new students, a policy already in place in New York City public schools since 2024. Hudson County schools currently require only immunization records, excluding TB testing.
Medical and Epidemiological Context
The Centers for Disease Control and Prevention (CDC) classifies *Mycobacterium tuberculosis* as a “serious but preventable” infection, with ~9 million new cases globally in 2024 and 1.5 million deaths. In the U.S., ~9,000 cases were reported in 2025, with foreign-born individuals accounting for 60% of diagnoses—a trend the NJDOH attributes to “recent immigration patterns and delayed diagnosis” among vulnerable populations.

Latent TB, as identified in the Tri-State High School student, is non-infectious but progresses to active TB in ~10% of untreated cases, per a **2023 meta-analysis in *The Lancet Infectious Diseases*. The WHO’s 2025 Global TB Report highlighted drug-resistant strains as a growing concern, though the NJDOH confirmed the Hudson County strain was pan-susceptible** (no resistance to first-line drugs).
Dr. Amara Ezeamama, director of the WHO’s Global TB Programme, told *The New England Journal of Medicine* in May 2026 that “school-based outbreaks remain a sentinel event” for broader public health failures. She noted that 95% of TB cases occur in low- and middle-income countries, but high-income nations like the U.S. see clusters in congregate settings—prisons, shelters, and now, schools.
In New Jersey, Hudson County has the highest TB rate in the state (3.2 cases per 100,000), driven by limited healthcare access and high population density. The NJDOH’s 2025 surveillance data showed that 40% of Hudson County TB cases were linked to foreign-born individuals from high-burden countries, though the Tri-State High School case involved a U.S.-born student with no travel history.
What Comes Next
- Complete environmental sampling in the school’s ventilation systems, restrooms, and high-traffic areas to assess *M. tuberculosis* viability.
- Expand community-wide TB screening in Bayonne, targeting hotspots with ≥5% foreign-born populations.
- Issue guidance on school ventilation upgrades, including HEPA filtration retrofits in older buildings.
- Convene a public hearing on June 20 to review Hudson County’s TB response protocols.
The Hudson County Board of Education has extended remote learning for grades 9–10 until June 17, with a decision on reopening pending NJDOH clearance. Superintendent Chen stated that the district was “exploring partnerships with local clinics” to offer on-site TB testing for students and staff.
For now, health officials urge vigilance without alarm. While the risk of widespread transmission remains low, the Tri-State High School case underscores the persistent, if often overlooked, threat of TB in modern public health. As Dr. Vasquez noted, “This is not an epidemic. But it is a wake-up call.”
Consult your healthcare provider if you have symptoms of TB (cough, fever, weight loss) or were in close contact with someone diagnosed with TB.
