Kansas is witnessing its largest documented tuberculosis (TB) outbreak in history, with 67 active cases and 79 latent infections reported in Wyandotte and Johnson counties. This unprecedented surge has raised significant public health concerns, although officials emphasize that the general risk to the public remains low.

Here’s what you need to know about the outbreak, symptoms, and preventive measures.
What Is Tuberculosis (TB)?
Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis, primarily affecting the lungs. It spreads through the air when an infected person coughs, sneezes, or speaks.
Key facts about TB:
- TB can be active (symptomatic and contagious) or latent (non-contagious and symptom-free).
- Without treatment, active TB can lead to severe health complications or death.
- TB is preventable and treatable with antibiotics.
Symptoms of Tuberculosis –
Common symptoms of active TB include:
- Persistent cough lasting over three weeks
- Chest pain
- Coughing up blood
- Fatigue and weakness
- Unexplained weight loss
- Fever and night sweats
While TB primarily affects the lungs, it can also infect other parts of the body, such as the spine, brain, kidneys, and lymph nodes, leading to specific symptoms depending on the organ involved.
Scope of the Kansas Outbreak
According to the Kansas Department of Health and Environment (KDHE), the outbreak has primarily affected Wyandotte County (60 active cases) and Johnson County (7 active cases). The state has also reported 79 latent TB infections.
In 2024, Kansas documented 109 active cases, a significant rise compared to the 46 cases reported in 2023. This increase includes cases of multidrug-resistant TB (MDR-TB), which is harder to treat due to its resistance to first-line antibiotics like rifampicin and isoniazid.
National Context:
This outbreak is the largest in the U.S. since the 1950s. Multidrug-resistant TB is becoming a growing concern, with global cases rising to over 410,000 in 2022.
Public Health Response
Health officials have implemented a series of measures to manage and contain the outbreak:
- Free Testing and Treatment: KDHE is offering no-cost TB testing and treatment for uninsured individuals and those whose insurance does not cover it.
- Contact Tracing: Identifying and testing individuals who have been in close contact with active TB patients.
- Public Awareness Campaigns: Educating residents about TB symptoms, transmission, and preventive strategies.
Ashley Goss, Deputy Secretary of KDHE, highlighted the importance of early detection and treatment, particularly for latent TB cases, to prevent their progression to active infections.
Preventive Measures and Recommendations
Health officials recommend the following steps to protect against tuberculosis:
- Get Tested: Individuals with known exposure to TB should undergo testing, even if symptom-free.
- Complete Treatment: Adhere to the full course of prescribed antibiotics to ensure the bacteria are completely eradicated.
- Practice Hygiene: Cover your mouth and nose when coughing or sneezing to prevent airborne transmission.
- Stay Informed: Follow updates from trusted health organizations like KDHE and the CDC.
Is the Public at Risk?
Despite the outbreak’s scale, health officials assure that the general risk of infection remains low for the public. TB typically requires prolonged, close contact with an infected individual to spread.
Conclusion
The Kansas tuberculosis outbreak is a stark reminder of the importance of public health vigilance. By staying informed and proactive, individuals can help prevent the spread of TB and protect their communities. Efforts by health officials, such as free testing and treatment programs, will play a vital role in controlling this historic outbreak.
