飞机和医院空气大多有无害的皮肤微生物;没有发现活性感染。 Airplane and hospital air mostly has harmless skin microbes; no active infections found.

2025年12月4日在Microbiome发表的一项新研究发现,飞机和医院空气中大部分含有人体皮肤无害微生物,没有证据表明检测到的潜在有害细菌会积极感染这些微生物。 A new study published in Microbiome on December 4, 2025, finds that airplane and hospital air contains mostly harmless microbes from human skin, with no evidence of active infection from detected potentially harmful germs. 研究人员分析了旅行者和保健工作者戴面罩的微生物,加上使用超过8 000小时的飞机过滤器,确定了407种物种。 Researchers analyzed microbes from face masks worn by travelers and healthcare workers, plus an aircraft filter used over 8,000 hours, identifying 407 species. 调查结果表明,在这些环境中,空气传播率较低,尽管手卫生对于防止地面传播仍然至关重要。 The findings suggest airborne transmission is low in these settings, though hand hygiene remains essential for preventing surface-based spread.
