In thinking of the history of epidemiology, the map usually comes to mind before the calendar or the clock. During the nineteenth century, the study of the pattern and distribution of disease commonly suggested a terrain, a spatial ordering, that might align with environmental hazards, or later, with bacteriological threats. One thinks, for example, of John Snow’s mapping of the prevalence of cholera in London, which now seems static, fixed at a certain point in time.¹ Of course, epidemiology always has been predicated on assumptions about change over time, or temporality—as the conventional triangulation of time, place and person indicates. And yet, whereas we talk freely of the ‘eras’ of epidemiology, conferring on the field a kind of historicity, rarely have we considered carefully and critically the various temporalities implicit in different styles of epidemiological investigation, the canon of chronological technique.² The question here, then, is not what is the history of epidemiology, but rather what is the history in epidemiology?

流行病学的历史

在考虑流行病学的历史时，通常会在日历或时钟之前想到地图。在19世纪，对疾病的模式和分布的研究通常提出了一种地形，一种空间秩序，它可能与环境危害或后来的细菌性威胁相吻合。例如，有人想到约翰·斯诺（John Snow）绘制的伦敦霍乱流行情况图，现在看来是静止的，固定在某个时间点。^1个当然，流行病学总是以关于时间或时间变化的假设为基础的，正如时间，地点和人的传统三角测量所表明的那样。然而，尽管我们随意谈论流行病学的“时代”，在该领域赋予了一种历史性，但很少有人仔细地和批判地考虑到流行病学调查的不同风格所隐含的各种时间性，这是时间技术的标准。²那么，这里的问题不是流行病学的历史是什么，而是流行病学的历史是什么？
