BACKGROUND: Suspected healthcare-associated tuberculosis (TB) transmission requires careful investigation due to its implications for infection prevention and public health.
CASE REPORT: We describe a suspected nosocomial TB transmission event that was investigated using whole genome sequencing (WGS). An 83-year-old man with an unexpected diagnosis of pleural TB and suspected pulmonary TB had shared a hospital room with a 52-year-old man undergoing investigation for metastatic lung cancer. The contact later developed pulmonary TB after commencing immunotherapy for pulmonary adenocarcinoma, raising concern for hospital transmission.
CONCLUSIONS: WGS demonstrated that the isolates belonged to different genomic lineages, excluding transmission. This case highlights the value of genomic surveillance in clarifying TB transmission events and guiding infection prevention responses.
