U.S. Tuberculosis Case Surveillance Data Since 1993

CDC WONDER's Online Tuberculosis Information System (OTIS) contains verified TB case data reported by U.S. states and territories since 1993. The dataset includes 22 variables such as age groups, race/ethnicity, sex, state, metropolitan area, patient risk factors, and drug resistance status. It is produced by the CDC's National Center for HIV/AIDS, viral Hepatitis, STD and TB Prevention and is updated annually with new cases and revisions.

Use Cases

• Analyze TB incidence rates and case counts by state and metropolitan area to identify geographic hotspots.
• Model the relationship between patient risk factors like HIV status, alcohol use, or homelessness and multi-drug resistant TB outcomes.
• Track trends in the percentage of cases completing therapy within one year of diagnosis across different age and race/ethnicity groups.
• Assess the distribution of disease verification criteria and directly observed therapy practices over time.

Strengths

• Provides longitudinal data with annual updates since 1993, allowing for long-term trend analysis.
• Includes 22 distinct variables covering demographics, geography, clinical outcomes, and patient risk factors.
• Data is reported by all U.S. state health departments, the District of Columbia, and Puerto Rico, ensuring national coverage.
• Case data is verified and extracted from the CDC's national TB surveillance system, ensuring a high degree of authority.

Limitations

• The dataset is provided in HTML format, which is not ideal for direct analysis and requires parsing or conversion.
• Specific row counts and file sizes are not disclosed, making it difficult to assess the dataset's scale for computational planning.
• The license is listed as 'other-license-specified', requiring users to investigate specific terms of use before application.
