Systematic Review and Meta-Analysis of TST Conversion Risk in Deployed Military and Long-Term Civilian Travelers

摘要

Transmission of tuberculosis (TB) during travel is a significant potential infectious disease threat to travelers. However, there is uncertainty in the travel medicine community regarding the evidence base for both estimates of risk for latent TB infection (LTBI) in long-term travelers and for information regarding which travelers may benefit from pre- or post-travel TB screening. The purpose of this study was to determine the risk for tuberculin skin test (TST) conversion, used as a surrogate for L TBI, in long-term travelers from low- to high-risk countries.
