Boarding issue in a commercial flight for patients with cavitary pulmonary tuberculosis: A case report

BACKGROUND Several studies have demonstrated that airborne transmission of Mycobacterium tuberculosis bacteria from patients with active pulmonary tuberculosis (TB) to other passengers or crew members can occur during long flights. As such, non-infectious TB patients are usually allowed to undertake air travel after taking the appropriate anti-TB drugs. However, the global guidelines for air travel for patients with TB are inconsistent and insufficiently detailed with respect to cavitary pulmonary TB (CPTB). CASE SUMMARY Here, we report a case in which a patient with multiple CPTB was permitted air travel, following negative sputum acid-fast bacilli smear tests after administration of proper anti-TB medication. The patient's culture results were pending. CONCLUSION This case revealed that more specific guidelines regulating air travel for patients with CPTB are necessary.
