A Clustered Pulmonary Tuberculosis Outbreak at a Technical School in Shenzhen, China

On 11 June 2025, a clustered outbreak of pulmonary tuberculosis was detected in a vocational school class in Shenzhen, China. The dataset describes a two-phase screening investigation involving 453 and 176 individuals, identifying 7 active and 42 latent infection cases, and includes results from symptom assessment, Interferon-Gamma Release Assays (IGRA), chest radiography, and whole genome sequencing. The data was authored by Jing Tang and published on figshare under a CC-BY-4.0 license in May 2026.

Use Cases

• Modeling tuberculosis transmission dynamics based on dormitory and class distribution data.
• Analyzing the correlation between IGRA positivity rates and active disease diagnosis.
• Studying the genetic relatedness of outbreak strains based on whole genome sequencing results.
• Evaluating the effectiveness of multi-phase screening protocols in educational settings.

Strengths

• Contains specific screening results for 453 and 176 individuals across two rounds.
• Reports precise case counts: 7 active tuberculosis cases and 42 latent infections.
• Includes comparative analysis of dormitory and class distributions with statistical significance (P < 0.05).
• Provides genetic homology data from whole genome sequencing of five isolates.

Limitations

• Dataset is a 23.9 KB DOCX file, suggesting limited structured data.
• Row count and column-level documentation are unknown.
• Data is specific to a single outbreak event, limiting generalizability.
