HOUSTON – A new report from Harris County Public Health shows Houston is leading the state in rates of tuberculosis, underscoring ongoing concerns about a disease many consider a relic of the past.
Tuberculosis, often referred to as TB, is an airborne illness that primarily affects the lungs but can spread to other parts of the body. It is transmitted through the air when an infected person coughs, speaks or sneezes.

Historically, TB was one of the deadliest diseases in the United States. In 1900, it claimed 194 lives per 100,000 people. While advances in medicine and public health efforts have dramatically reduced those numbers, officials say the disease has not been eradicated.
According to the report, Harris County recorded 5.5 active tuberculosis cases per 100,000 residents in 2024, the most recent year of available data.
Health officials emphasize that TB is both preventable and treatable, but it requires early detection and consistent medical care. Symptoms can include a persistent cough, chest pain, fever and weight loss.
The report highlights the need for continued public health vigilance, particularly in densely populated urban areas like Houston, where the risk of transmission can be higher.
Officials encourage residents to seek medical attention if they experience symptoms or believe they may have been exposed.
