Yaws, caused by Treponema pallidum subsp pertenue, was the first disease to be targeted for eradication by WHO.¹ As with other treponemal infections, such as syphilis, some people develop latent infection. These individuals have positive serological test results for yaws but no clinical signs of disease. Importantly, latent yaws can relapse, which most frequently occurs in the first 5 years after infection,² and, therefore, these people represent an important source of reinfection in endemic communities.

单剂量阿奇霉素治疗潜在的偏航

由梅毒螺旋体亚种引起的偏航是世界卫生组织第一个要根除的疾病。¹与梅毒等其他螺旋体感染一样，有些人会潜伏感染。这些个体的偏航性血清学测试结果均为阳性，但无临床疾病迹象。重要的是，潜在的偏航可能会复发，这种情况最常发生在感染后的头5年²，因此，这些人是地方性社区再次感染的重要来源。
