This article offers an innovative attempt to construct an empirically-based estimate of the extent of syphilis prevailing in two contrasting populations in late eighteenth-century Britain. Thanks to the co-incident survival of both a detailed admissions register for Chester Infirmary and a pioneering census of the city of Chester in 1774 taken by Dr John Haygarth, it is possible to produce age-specific estimates of the extent to which adults of each sex had been treated for the pox by age 35. These estimates can be produced both for the resident population of Chester city and comparatively for the rural region immediately surrounding Chester. These are the first estimates of the prevalence of this important disease produced for the eighteenth century and they can be compared with similar figures for England and Wales c. 1911–1912.

早期现代英格兰的痘治疗率：对 1770 年代切斯特市及其农村地区梅毒流行率的比较估计

本文提供了一种创新的尝试，以建立一个基于经验的估计，对 18 世纪后期英国两个截然不同的人群中盛行的梅毒程度进行估计。由于切斯特医院的详细入院登记册和约翰·海加斯博士于 1774 年进行的切斯特市开创性人口普查同时存在，因此有可能对每个成年人在性已在 35 岁时接受了痘治疗。这些估计可以针对切斯特市的常住人口和紧邻切斯特的农村地区进行比较。这些是对 18 世纪这种重要疾病流行率的首次估计，可以与英格兰和威尔士的类似数字进行比较 c。1911-1912 年。
