The emergence of disease threats can take many forms, from the adaptation of a traditionally zoonotic pathogen for efficient spread in humans, to the development of antibiotic resistance in well-known pathogens, to the creation of new niches for established disease through social and societal changes. In this commentary, the authors explore these various facets of disease emergence through the lens of the papers included in this issue of Epidemiologic Reviews. The authors explore multiple aspects of emergence and the ways in which emergent pathogens can be controlled with the limited tools available. In doing so, they put the papers in this issue in the context of the broader research agenda around understanding and combatting emergent pathogens.

新出现和重新出现的传染病的许多面孔。

疾病威胁的出现可以采取多种形式，从适应传统的人畜共患病原体以使其有效传播到人类，到发展众所周知的病原体对抗生素的抵抗力，或者通过社会和社会变革为已确定的疾病创造新的生态位。 。在这篇评论中，作者通过本期《流行病学评论》所载论文的视角探讨了疾病出现的各个方面。作者探讨了出现的多个方面，以及可以使用有限的工具来控制出现的病原体的方法。通过这样做，他们将论文放在围绕理解和对抗新兴病原体的更广泛研究议程的背景下。
