The purpose of this study was to describe and compare the transmission dynamics of chlamydia and gonorrhea in Winnipeg, Manitoba, Canada, and to assess implications for control programs.
Chlamydia and gonorrhea surveillance case reports (1988 through 1995) and contact-tracing reports (1991 through 1995) were examined.
High incidence rates of both chlamydia and gonorrhea clustered in geographic core areas characterized by low socioeconomic status. A decline in the number of reported cases of chlamydia (61%) and gonorrhea (64%) occurred between 1988 and 1995. For chlamydia, the decline was most prominent in non-core area cases, while for gonorrhea it was similar in core and non-core areas.
Chlamydia and gonorrhea appear to be evolving through different epidemic phases, with chlamydia transmission, in response to a newly introduced control program, becoming more core dependent and gonorrhea transmission becoming more sporadic in the face of a sustained control effort. Focused control programs, based on an understanding of the transmission dynamics of chlamydia and gonorrhea, may make their elimination a feasible goal.
本研究旨在描述和比较加拿大曼尼托巴省温尼伯市衣原体和淋病的传播动态,并评估对防控计划的影响。
对衣原体和淋病监测病例报告(1988年至1995年)以及接触者追踪报告(1991年至1995年)进行了审查。
衣原体和淋病的高发病率集中在社会经济地位较低的地理核心区域。1988年至1995年间,报告的衣原体病例数(61%)和淋病病例数(64%)有所下降。对于衣原体,非核心区域病例的下降最为显著,而对于淋病,核心区域和非核心区域的下降情况相似。
衣原体和淋病似乎正经历不同的流行阶段,随着一项新引入的防控计划的实施,衣原体传播变得更加依赖核心区域,而面对持续的防控努力,淋病传播变得更加零星。基于对衣原体和淋病传播动态的理解制定有针对性的防控计划,可能会使消除这两种疾病成为一个可行的目标。
