Epi Profile Section 3 - Affected Populations


Non-US Born Residents

Being born in and/or extensive travel to a high incidence country is a major risk factor for contracting TB infection and TB disease. Persons born outside of the United States accounted for 61% of TB cases in Texas for 2017, compared to 70% of cases nationally.  Of the cases born outside of the US, 49% were born in Mexico. Below are the top 15 countries of birth for 2017 cases.

Texas-Mexico Border

Tuberculosis rates are higher along the Texas-Mexico border. Of the 14 border counties that reported TB cases in 2017, only one had a case rate lower than the Texas case rate of 4.0 cases per 100,000. Given the travel across international borders between counties along the Texas-Mexico border, local and regional health departments are faced with unique challenges relating to TB prevention and care. In an effort to address these challenges, the DSHS TB and Hansen’s Disease Branch Binational Program provides services including case management, contact investigations, and TB infection treatment for individuals who have ties to the United States and Mexico. These four binational programs are located in cities along the Texas-Mexico border:

  • Juntos in El Paso, Texas
  • Los Dos Laredos in Laredo, Texas
  • Grupo Sin Fronteras in Brownsville, Texas and McAllen, Texas
  • Esperanza y Amistad in Del Rio, Texas and Eagle Pass, Texas

In 2017, 28.8% of cases diagnosed along the Texas border counties were under 30 years of age. Additionally, 6.4% of these cases were under 10 years of age, compared to 3.2% of cases in non-border counties for 2017.

Child Morbidity

From 2013-2017, Texas accounted for 18% of all US cases diagnosed between ages 0-4 years old, the highest percentage of any state. In comparison, Texas reports 10.9% of US cases for all age groups. Consistently over the last five years, the most common age of children 0-4 being diagnosed with active TB disease is one-year-old. Furthermore, 94% of cases aged 0-4 years were born in the US and 86% did not report travel to a high incidence country.  This can be an indication of recent transmission, due to the age.
