3 Cases in Maine, One Global Warning: Tuberculosis Is Back

The Return of TB: How America’s Health Net Got Holes

Three new tuberculosis cases in Maine highlight a troubling U.S. trend. Once in decline, TB is resurging nationwide. Here’s why experts call it the world’s deadliest infectious disease and what it means for public health.

Introduction – A Wake-Up Call From Maine

For most Americans, tuberculosis (TB) feels like a relic of the past, something belonging to dusty history books or old black-and-white hospital photos. The word itself conjures Victorian-era sanatoriums tucked away in mountain towns where patients were sent to breathe fresh air and rest, often with little hope of survival. For decades, public health victories made TB fade from our national consciousness. Vaccines, antibiotics, and strict control programs pushed rates down year after year, to the point where most people believed the disease had been conquered.

But this September, Maine health officials confirmed three active tuberculosis cases in the Greater Portland area. On the surface, three may sound like a small number, but public health experts warn it’s a signal with global echoes. These isolated cases connect to a troubling reality: TB is quietly resurging, not just in the United States but around the world. And the timing couldn’t be worse.

The question now isn’t simply about Maine. It’s bigger: why is TB back, what’s fueling its return, and what does this mean for the future of public health?

The Cases in Maine – Not an Outbreak, But a Warning

According to the Maine Center for Disease Control and Prevention (Maine CDC), three individuals in the Greater Portland area tested positive for active tuberculosis in early September 2025. Officials quickly emphasized that these were separate cases, not linked in a single outbreak. Contact tracing began immediately, with health workers reaching out to anyone who might have been exposed so they could be tested.

Lindsay Hammes, spokesperson for the Maine CDC, explained that each case appeared to have come from different sources of infection. That fact is both reassuring and concerning. On the one hand, it indicates that Maine isn’t dealing with a contained outbreak in a single location, such as a school or workplace. On the other hand, it indicates that TB is creeping through different channels of society, not always easy to predict, trace, or contain.

By the end of July, Maine had already logged 28 TB cases in 2025. That’s a small figure compared to the national population, but higher than in many previous years. State officials are careful not to use the word “outbreak.” Still, epidemiologists see these numbers as part of a larger pattern: TB is ticking upward across the U.S. after decades of decline.

Tuberculosis 101 – What Everyone Should Know

Before diving deeper into the resurgence, it’s worth pausing to understand what TB actually is, because for many people under 40, it’s almost an unfamiliar disease.

What causes TB?
Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis. It usually attacks the lungs, but it can also affect the brain, kidneys, bones, and other parts of the body.
How does it spread?
TB spreads through the air when a person with active TB coughs, sneezes, or speaks. Unlike the flu or COVID-19, it usually requires prolonged close contact to catch.
Latent vs. Active TB:
- Latent TB means someone is infected but shows no symptoms and cannot spread it.
- Active TB means the disease is “turned on,” producing symptoms and becoming contagious.
Common Symptoms of Active TB:
- Persistent cough lasting 3 weeks or more
- Coughing up blood or thick sputum
- Chest pain
- Fatigue, weight loss, fever, night sweats
Treatment:
TB is curable with antibiotics, but the regimen is long, often 6–9 months of multiple drugs. Patients who don’t finish treatment risk relapse or worse: the development of drug-resistant TB.

Globally, TB remains the world’s deadliest infectious disease, claiming around 1.3 million lives in 2022, according to the World Health Organization. It kills more people each year than HIV/AIDS and malaria combined.

Why TB Is Rising Again in the U.S.

For decades, U.S. public health programs worked relentlessly to track, test, and treat TB. The results were dramatic: cases dropped steadily throughout the 20th century. By the early 2000s, TB seemed like a problem mainly confined to other parts of the world. Then came 2020.

1. The Pandemic Effect

When COVID-19 swept across the globe, healthcare systems diverted resources to handle the crisis. TB testing, screening, and routine treatments took a back seat. Many people had missed diagnoses or delayed care. The result was a “hidden pool” of infections that later reemerged.

2. Immigration & Global Mobility

Historically, U.S. ports like Ellis Island screened immigrants for TB and quarantined those infected. Modern immigration practices are more complex, and with high global migration, cases from countries where TB is still common are appearing in American communities.

3. Drug Resistance

Misuse or incomplete use of TB antibiotics over decades has created multidrug-resistant TB (MDR-TB). These cases are more complex, more expensive, and more dangerous to treat.

4. Social Inequities

TB thrives where healthcare access is limited, housing is crowded, and people lack consistent nutrition. Homeless shelters, prisons, and low-income communities often see higher risks.

5. Complacency

Because TB felt “defeated,” funding and awareness programs shrank. Fewer doctors today are trained to spot it quickly, which delays diagnosis and fuels spread.

The Maine cases aren’t anomalies; they’re symptoms of all these combined forces.

TB in Schools – A Troubling Trend

Alongside Maine’s news, two other recent cases added urgency to the national picture:

California: A high school student in Riverside County tested positive for active TB in late August. The student is under treatment and expected to recover.
Michigan: Another high school case was reported just days earlier, prompting widespread testing among classmates.

Children and young adults typically aren’t the face of TB stories, but these recent cases show how the disease can surface in places once considered safe. Schools are tight-knit environments, which makes quick detection and treatment essential.

The Global Angle – A Disease That Never Left

While Americans talk about TB as if it’s making a “comeback,” the truth is TB never left the global stage.

In India, China, Indonesia, Nigeria, and Pakistan, TB remains a leading cause of death.
The WHO estimates nearly 10.6 million people fell ill with TB in 2022 alone.
Drug-resistant TB is spreading fastest in Eastern Europe, Central Asia, and Africa.

Public health experts warn that unless countries work together, TB could undo decades of medical progress, and the Maine cases are proof that local health stories are global health stories.

The Politics of TB – Immigration, Borders, and Public Fear

In the U.S., discussions about TB often spiral into political debates. Comment sections light up with people blaming immigration policies, pointing out how Ellis Island once quarantined newcomers, while modern practices appear more relaxed.

While it’s true that TB is more common in some countries, experts caution against oversimplification. TB can spread within U.S. communities, too, especially in environments where people lack access to healthcare. But the perception persists: TB’s rise is linked to border policies, international travel, and insufficient screening.

This political angle makes TB more than just a medical issue; it becomes a cultural flashpoint, one that can either lead to stronger public health strategies or further polarization.

Fighting Back – How TB Can Be Controlled

The good news? TB, even today, is curable and preventable. What it requires is persistence, something modern healthcare often struggles with.

Strategies That Work:

Rapid Testing and Contact Tracing
Finding cases early, as Maine is doing, prevents spread.
Consistent Treatment Programs
Patients must finish months-long antibiotic regimens. Public health departments often assign nurses to supervise treatment and care.
Addressing Social Conditions
Tackling homelessness, prison health, and poverty reduces TB hotbeds.
Global Cooperation
Because TB respects no borders, wealthy countries must support efforts in high-burden nations.
Vaccine Development
The BCG vaccine, used in many countries, is outdated and offers limited protection. New vaccines are under research but not yet widely available.

The Human Side – Stories Behind the Numbers

Numbers and charts make TB sound clinical, but at its core, this is a human disease. Each case represents a person whose life is disrupted for months, if not years. Treatments often come with side effects: nausea, vision changes, and hearing loss. Patients face stigma, too, and the old stereotypes of TB as a “dirty” disease persist.

In Maine, local health officials emphasize privacy, but anyone who’s gone through TB treatment will tell you: it’s not just a medical battle, it’s an emotional one. Many patients endure isolation, fear of infecting loved ones, and the grind of daily medication.

Conclusion – Why Maine Matters to Everyone

Three TB cases in Maine may sound minor. However, history shows that infectious diseases don’t need big numbers to have a significant impact. Just as one COVID-19 case ballooned into a global pandemic, a single TB spark in the wrong setting can create cascading consequences.

The Maine cases are not yet a crisis. But they are a reminder: public health victories can unravel when vigilance fades. Tuberculosis, the so-called disease of the past, is proving it has a future if we don’t act decisively.

Maine’s warning is not just for New England. It’s for all of us.
