Much has been learnt of the epidemiology of yaws during eradication campaigns in populations in which the prevalence of active yaws was high, but not all has been published. The recognition of the importance of latent cases in the maintenance of yaws has contributed to the effectiveness of these campaigns. Yaws eradication activities are extending into populations where at present active yaws is often not high. Planning of effective and economical eradication measures, especially in such populations, needs as complete a picture of the disease as possible, from its transmission and the factors that favour this until the death of the infected person, before or after cure of the infection either after chemotherapy or spontaneously.By revealing the many gaps that still remain in our knowledge of yaws, this summary may encourage those who have gathered valuable material during field work to study and prepare it for publication.
在雅司病流行率高的人群中开展根除运动期间,人们对雅司病的流行病学有了很多了解,但并非所有内容都已发表。认识到潜伏病例在雅司病传播中的重要性有助于这些运动取得成效。雅司病根除活动正在扩展到目前活动性雅司病发病率通常不高的人群。制定有效且经济的根除措施,尤其是在这类人群中,需要尽可能全面地了解这种疾病,从其传播方式和促成传播的因素,到感染者在化疗或自然治愈感染后痊愈之前或之后的死亡情况。通过揭示我们对雅司病认识中仍然存在的诸多空白,本综述可能会鼓励那些在实地工作中收集了宝贵资料的人对其进行研究并准备发表。
