在八十年代的后5年中,美国发生了梅毒的流行。在1990年,不同地区梅毒发病率比较结果表明,南部地区发病率最高,其次是东北、西部和中西部地区。从1986～1990年,一期和二期梅毒的发病率表现了不同的地区流行模式,需要更详细地分析梅毒在不同地区各种人群中的流行,以更好地了解各地区梅毒的流行模式。不同地区间资料的比较有助于评价在梅毒流行期间哪一种性传播疾病的防治规划最为有效。
In the second half of the 1980s syphilis was prevalent in the United States. In 1990, the incidence of syphilis in different regions showed that the incidence was highest in southern China, followed by the northeast, western and central and western regions. From 1986 to 1990, the incidence of first- and second-stage syphilis showed a pattern of prevalence in different regions, requiring a more detailed analysis of the prevalence of syphilis in various populations in different regions to better understand the prevalence patterns of syphilis in various regions . Comparisons of data from different regions help to assess which STD prevention and control program is most effective during the syphilis epidemic.
