Why TB Testing Matters: Symptoms, Risks, and the Most Recent Tuberculosis Outbreak

The most recent outbreak of tuberculosis (TB) in the Kansas City area has put the spotlight on a disease that many people may not think about until it becomes a public health crisis. With more than 65 active cases reported in Wyandotte and Johnson counties, this outbreak is one of the largest in U.S. history, raising serious concerns about how TB spreads and who is at risk. 

This outbreak is a reminder of how important early detection and testing are in controlling tuberculosis. Regular screening not only helps prevent the spread of TB but also ensures that individuals, especially those undergoing immigration medical exams, receive the care they need to stay healthy. Catching TB early through routine testing allows for timely treatment, reducing complications and protecting both individuals and the broader community. 

Understanding Tuberculosis (TB)

Tuberculosis is a highly contagious lung disease caused by the bacterium Mycobacterium tuberculosis. It spreads through airborne droplets when an infected person coughs, sneezes, or speaks. TB primarily affects the lungs but can also impact other parts of the body, such as the brain and spine.

There are two forms of TB:

• Latent TB: In this form, the bacteria remain inactive in the body and cause no symptoms. Individuals with latent TB are not contagious but carry a risk of developing active TB later in life.
• Active TB: This form is symptomatic and contagious. Symptoms include a persistent cough lasting more than three weeks, chest pain, coughing up blood, fatigue, weight loss, fever, and night sweats. Immediate medical attention is essential for active TB cases.

How TB Spreads

TB is transmitted through the air when an infected person releases bacteria by coughing, sneezing, or speaking. These bacteria can remain airborne for hours, posing a risk to individuals who inhale them. Crowded and enclosed spaces, such as shelters, hospitals, detention centers, and public transportation, facilitate the spread of TB. Global travel also contributes to the dissemination of TB, as individuals from regions with high TB prevalence may unknowingly carry the bacteria.

Early Symptoms of Tuberculosis

Recognizing the early signs of TB is crucial for prompt diagnosis and treatment. Key symptoms to watch for include:

• Persistent cough lasting more than three weeks
• Chest pain
• Coughing up blood
• Unexplained weight loss
• Fatigue
• Fever
• Night sweats

If you experience any of these symptoms, it is essential to seek medical attention promptly.

Key Risk Factors for TB

Certain factors increase the risk of contracting TB:

• Weakened Immune System: Individuals with conditions such as HIV, diabetes, or cancer are more susceptible to TB due to compromised immunity.
• Close Contact: Living or working in close proximity to someone with active TB increases the risk of transmission.
• Healthcare Workers: Medical professionals are at higher risk due to potential exposure to infected patients.
• Immigrants from High TB-Burden Countries: People from regions with high TB prevalence, including parts of Asia, Africa, and Latin America, are at increased risk.

TB Testing and Immigration

The U.S. Citizenship and Immigration Services (USCIS) mandates TB screening for immigration applicants to ensure public health safety. USCIS-approved civil surgeons conduct comprehensive medical examinations, including TB testing, to detect both latent and active TB cases.

The screening process typically involves:

• Interferon-Gamma Release Assays (IGRAs): Blood tests that measure the immune system's response to TB bacteria.
• Chest X-Ray: If initial tests suggest TB infection, a chest X-ray is performed to assess lung involvement.

Preventing TB and Protecting Yourself

Preventive measures are essential to reduce the risk of TB transmission:

• Vaccination: The Bacille Calmette-Guérin (BCG) vaccine is commonly administered in countries with high TB prevalence. However, it does not provide complete protection against TB and is not used in the United States.
• Regular Testing: Individuals at higher risk, such as healthcare workers and those with weakened immune systems, should undergo regular TB testing.
• Good Hygiene Practices: Covering the mouth and nose when coughing or sneezing, proper handwashing, and wearing masks in crowded places can help prevent the spread of TB.
• Improved Ventilation: Ensuring adequate airflow in living and working spaces reduces the concentration of airborne TB bacteria.
