Travelers' diarrhea affects up to 60% of visitors to tropical and subtropical regions. Although symptoms are generally self-limited, some infections are associated with significant morbidity and occasional mortality. Newer molecular diagnostic techniques allow for highly sensitive, specific, and expeditious testing of a wide range of potential pathogens. Identification of the causative pathogen of travelers' diarrhea allows for targeted therapy and management and a reduction in empiric broad-spectrum coverage.
旅行者腹泻影响高达 60%的热带和亚热带地区的游客。尽管症状通常是自限性的，但有些感染与显著的发病率和偶尔的死亡率有关。新的分子诊断技术可高度敏感、特异和快速地检测广泛的潜在病原体。确定旅行者腹泻的病原体可进行针对性治疗和管理，并减少经验性广谱覆盖。
