In 1976-8 the incidence of syphilis in Amsterdam doubled from 41 to 88 per 100,000. Contact tracers identified two major risk groups, homosexual men with multiple partners and prostitutes using drugs, and special surveillance programmes for these groups have been organised on a regular basis since 1979. As a result of these two programmes the incidence of syphilis started to decline appreciably in 1981-3. From 1984 onwards a further decline occurred in men as a result of a change of lifestyle by homosexual men, probably because of the appearance of AIDS. In 1985 the incidence of syphilis in Amsterdam had dropped to 30 per 100,000, the lowest level since notification started.
1976年至1978年期间，阿姆斯特丹梅毒发病率翻了一番，从每10万人41例增至88例。接触者追踪人员确定了两个主要风险群体，即有多个性伴侣的男同性恋者和吸毒的妓女，自1979年以来定期为这些群体组织了特别监测项目。由于这两个项目，梅毒发病率在1981年至1983年开始显著下降。从1984年起，由于男同性恋者生活方式的改变，可能是由于艾滋病的出现，男性梅毒发病率进一步下降。1985年，阿姆斯特丹梅毒发病率降至每10万人30例，为开始通报以来的最低水平。
