Tuberculosis, sometimes called “the white plague,” is quietly making a comeback in the United States. After decades of decline, the Centers for Disease Control and Prevention (CDC) reported more than 10,600 confirmed TB cases in 2024. For a disease many people thought belonged to history books, this rise can feel unsettling — especially after everything we’ve just lived through with COVID‑19.

In this guide, we’ll walk through why TB cases are rising post‑pandemic, what experts mean by a “rebound effect,” who’s most at risk, and the concrete steps you can take to stay safe. The goal is not to scare you, but to give you clear, evidence‑based information so you can make calm, confident decisions for yourself and your family.

What Is Tuberculosis — and Why Is It Called the “White Plague”?

Tuberculosis is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It most often affects the lungs (pulmonary TB), but it can also involve the brain, spine, kidneys, and other organs. Historically, people with advanced TB would lose weight, become very pale, and cough up blood — leading to the dramatic nickname “the white plague.”

TB spreads through the air when a person with active pulmonary TB coughs, speaks, laughs, or sings in close proximity to others. It’s not as contagious as measles or COVID‑19, but long or repeated exposure, especially in poorly ventilated indoor spaces, increases risk.

  • Latent TB infection (LTBI): You have the bacteria in your body, but your immune system keeps it under control. You have no symptoms and you can’t spread TB to others, but you can develop active TB later.
  • Active TB disease: The bacteria are multiplying, usually causing symptoms such as cough, fever, night sweats, and weight loss. At this stage, TB can spread to others and requires prompt treatment.
“Without treatment, TB disease can be fatal. With timely, appropriate therapy, most people with TB can be cured.” — U.S. Centers for Disease Control and Prevention (CDC)

The Post‑Pandemic TB “Rebound Effect”: What the Numbers Show

During the height of the COVID‑19 pandemic, TB case counts in the U.S. dropped. At first glance, that looked like progress — but many experts warned it might be misleading. Now, with more than 10,600 confirmed cases reported in 2024, we’re seeing what public health officials call a “rebound effect.”

Several factors likely explain this rebound:

  1. Missed diagnoses during the pandemic: People delayed or skipped care; overwhelmed health systems focused on COVID‑19. TB symptoms like cough and fever were sometimes attributed only to COVID.
  2. Disrupted TB services: Screening programs, contact tracing, and preventive treatment were interrupted in many places.
  3. Social and economic strain: Crowded housing, unstable work, limited access to healthcare, and poor nutrition can all increase TB risk over time.
  4. Gradual return to normal activity: As people resumed work, school, travel, and socializing, opportunities for TB transmission increased again.

TB Symptoms and “Silent” Infection: What You Should Watch For

One of the challenges with tuberculosis is that latent infection has no symptoms at all. Many people live for years unaware they’re infected, only developing active disease when their immune system becomes weaker due to age, illness, or stress.

Symptoms of active pulmonary TB can include:

  • Cough lasting three weeks or longer
  • Coughing up blood or mucus
  • Chest pain or pain with breathing or coughing
  • Unexplained weight loss
  • Fever and chills
  • Night sweats that soak sleepwear or bedding
  • Fatigue and weakness
  • Loss of appetite

TB outside the lungs (extrapulmonary TB) can cause different symptoms depending on the organ involved — for example, back pain if the spine is affected or headaches and confusion if TB reaches the brain.


Who Is Most at Risk for Tuberculosis in the U.S.?

Tuberculosis can affect anyone, but certain groups are more likely to be exposed to TB bacteria or to progress from latent infection to active disease. Understanding risk doesn’t mean assigning blame; it helps focus prevention and testing where it’s needed most.

According to public health guidance, higher‑risk groups include:

  • People who have spent time with someone known or suspected to have active TB
  • Healthcare workers and staff in settings such as hospitals, clinics, and long‑term care facilities
  • People born in, or frequently traveling to, countries where TB is more common
  • Residents and staff of shelters, correctional facilities, and other congregate settings
  • People with weakened immune systems (e.g., HIV infection, certain cancers, organ transplants, or immune‑suppressing medications)
  • Individuals with conditions like diabetes, chronic kidney disease, or malnutrition
  • People who use tobacco or substances that can weaken lung function or immunity

How TB Is Diagnosed: Tests You Might Be Offered

If your clinician is concerned about TB — because of your symptoms, risk factors, or close contact with someone who has TB — they may use several steps to confirm or rule it out.

1. Tests for Latent TB Infection

  • TB blood test (IGRA): A single blood draw; results are typically available within days. Often preferred for adults and for people who have had the BCG TB vaccine.
  • TB skin test (TST or Mantoux test): A small amount of fluid injected just under the skin, usually on the forearm. A healthcare worker checks the site 48–72 hours later.

2. Tests for Active TB Disease

  • Chest X‑ray or other imaging: Looks for lung changes suggestive of TB.
  • Sputum tests: Samples of mucus you cough up are examined for TB bacteria using microscopy, molecular tests, and culture.
  • Additional tests for non‑lung TB: Depending on symptoms, this may involve fluid analysis, biopsies, or advanced imaging.

TB Treatment Today: Effective but Requires Commitment

Modern TB treatment is highly effective, but it is not a quick course of antibiotics. The bacteria that cause TB grow slowly and can be stubborn, so treatment plans are designed to fully clear the infection and prevent relapse or drug resistance.

Treatment for Latent TB Infection

Treating latent TB reduces your lifetime risk of developing active disease. Regimens often include:

  • Short‑course options (e.g., 3–4 months) using combinations of TB medicines such as isoniazid and rifampin or related drugs
  • Longer‑course options (e.g., 6–9 months) when short‑course therapy isn’t suitable

Treatment for Active TB Disease

Active TB usually requires:

  • A combination of at least four TB medicines at the start of treatment
  • Daily or near‑daily dosing for a minimum of 4–6 months, sometimes longer
  • Regular follow‑up visits, lab tests, and possibly directly observed therapy (DOT), where a healthcare worker helps you stay on track

TB treatment can last months, so practical tools like pill organizers, reminders, and support systems are crucial for completing therapy.

Drug‑resistant TB — strains that don’t respond to standard medicines — remains relatively uncommon in the U.S. but is a serious concern worldwide. Completing treatment exactly as prescribed is one of the best protections against resistance.


Common Obstacles: Stigma, Fear, and Life Getting in the Way

Many people delayed seeking care during the pandemic, and that habit can linger. There’s also stigma: some still associate TB with poverty or “uncleanliness,” which is both inaccurate and harmful. On top of that, multi‑month treatment can feel overwhelming when you’re juggling work, caregiving, and financial stress.

In one clinic I worked with, a middle‑aged man delayed evaluation for a chronic cough because he was worried about missing work and didn’t want anyone to think he had “something contagious.” When he did come in, imaging and sputum tests showed active TB. With the support of a case manager, his employer, and a local TB program, he completed treatment and recovered fully — and shared later that the hardest part had been the fear of being judged.

If any of this sounds familiar, you’re not alone. Here are some ways to navigate those obstacles:

  • Ask about confidentiality: TB programs are used to handling sensitive information and protecting your privacy.
  • Explore support services: Many health departments offer transportation help, counseling, or incentives to support treatment completion.
  • Break it down: Focus on one appointment or one week of medication at a time, rather than the whole treatment course.
  • Involve trusted people: A friend, partner, or family member can help with reminders and emotional support, if you feel comfortable sharing.

Practical Ways to Protect Yourself and Others from TB

While you can’t reduce TB risk to zero, you can significantly lower it — and help protect your community — with a few practical, evidence‑based steps.

1. Know Your Risk and Ask About Testing

  • If you’ve lived, worked, or traveled extensively in higher‑TB regions, talk with your clinician about TB testing.
  • If you’re a healthcare worker or live in a congregate setting, follow local screening recommendations.
  • If you’ve had close contact with someone with TB, seek evaluation promptly, even if you feel well.

2. Improve Air and Space When Possible

  • Open windows or use fans to improve ventilation in crowded indoor spaces when feasible.
  • In healthcare or high‑risk settings, follow guidance on masks, air filtration, and isolation procedures.

3. Support Overall Immune Health

No diet or supplement can “cure” or “prevent” TB on its own, but basic health habits support the immune system that keeps latent TB in check:

  • A balanced diet with adequate protein, fruits, and vegetables
  • Enough sleep most nights
  • Managing chronic conditions like diabetes with your healthcare team
  • Avoiding tobacco and limiting exposure to secondhand smoke

While lifestyle alone cannot prevent TB, good nutrition, rest, and management of chronic conditions support the immune system’s ability to fight infection.

Relying on authoritative sources like the CDC and WHO helps you stay informed about TB without being overwhelmed by sensational headlines.

Moving Forward: Stay Alert, Not Afraid

The rise in U.S. tuberculosis cases after the COVID‑19 pandemic is a reminder that old infections don’t disappear just because we stop hearing about them. But it’s also a reminder of what works: early diagnosis, effective treatment, and steady public health efforts.

You don’t need to become an infectious disease expert to protect yourself and those around you. A few key actions — recognizing symptoms, knowing your risk, seeking care when something feels off, and finishing any prescribed TB treatment — go a long way.

If you’re concerned about TB because of your symptoms, your work, your living situation, or a recent exposure, reach out to a healthcare professional or local health department. Bringing your questions into the open is the first and most powerful step toward staying healthy in a world where infections old and new will keep evolving.
