Tuberculosis in Texas: trends and issues in surveillance
Texas Medicine
|August 26, 1998
Summary
Tuberculosis (TB) incidence was higher in racial/ethnic minorities in Texas. However, poor data quality limits trend analysis for TB risk factors like country of origin and substance abuse.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- Tuberculosis (TB) remains a significant public health concern.
- Understanding risk factors and trends is crucial for effective control strategies.
- Previous studies have highlighted disparities in TB incidence.
Purpose of the Study:
- To examine risk factors and trends associated with tuberculosis (TB) in Texas between 1987 and 1993.
- To identify demographic and behavioral factors contributing to TB incidence.
- To assess the quality of data used for TB surveillance in Texas.
Main Methods:
- Retrospective analysis of TB surveillance data from Texas (1987-1993).
- Investigation of risk factors including race/ethnicity, country of origin, group risk, individual risk (alcohol/drug abuse), and occupational risk.
- Evaluation of data completeness for key surveillance fields.
Main Results:
- Significantly higher TB incidence observed among racial/ethnic minorities compared to whites.
- Increasing percentage of TB cases among individuals born in Mexico or Vietnam.
- Individual risk factors (alcohol/drug abuse) trends mirrored national patterns.
- Substantial data quality issues, with low completion rates for country of origin, individual risk, group risk, and occupational risk fields.
Conclusions:
- Racial/ethnic minorities and foreign-born individuals (from Mexico, Vietnam) were disproportionately affected by TB in Texas during the study period.
- Poor data quality significantly limits the validity of identified TB trends and risk factor analyses in Texas.
- Recommendations for improving TB surveillance data completeness are essential for accurate public health assessments.

01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:26Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

01:28Pulmonary Tuberculosis V
Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
