After many years of decline, the incidence of gonorrhea in Sweden reached an all-time low of 2.4 cases per 100,000 inhabitants in 1996; however, the incidence has been increasing since 1997.
To describe the reemergence of gonorrhea in Sweden using clinical epidemiologic data and microbiologic characterization of isolated strains of Neisseria gonorrhoeae.
N gonorrhoeae strains isolated in Sweden from February 1998 to January 1999 were serotyped and an epidemiologic data questionnaire was sent to each clinician reporting a case of gonorrhea.
Epidemiologic and microbiologic data were obtained for 357 cases (91% of all cases diagnosed during the period). Domestic cases had significantly increased since 1997. Serovar IB-3 was the most common isolate in domestic cases of heterosexually exposed teenagers, and serovar IB-2 was the most frequent isolate in domestic cases of homosexually exposed men. Of the imported cases, 47% were exposed in Asia and 6.5% were exposed in Eastern Europe.
The increase of gonorrhea in Sweden is due to an increase of domestic cases. Heterosexual teenagers and homosexual men were identified as core groups infected by different serovars of N gonorrhoeae.
经过多年下降后，瑞典的淋病发病率在1996年降至历史最低点，每10万居民中有2.4例；然而，自1997年以来发病率一直在上升。
利用临床流行病学数据和淋病奈瑟菌分离株的微生物学特征描述瑞典淋病的再度出现。
对1998年2月至1999年1月在瑞典分离出的淋病奈瑟菌菌株进行血清分型，并向每位报告淋病病例的临床医生发送一份流行病学数据调查问卷。
获得了357例病例的流行病学和微生物学数据（占该时期诊断的所有病例的91%）。自1997年以来本土病例显著增加。血清型IB-3是异性接触青少年本土病例中最常见的分离株，血清型IB-2是同性接触男性本土病例中最常见的分离株。在输入性病例中，47%在亚洲接触感染源，6.5%在东欧接触感染源。
瑞典淋病发病率上升是由于本土病例增加。异性青少年和同性男性被确定为感染不同血清型淋病奈瑟菌的核心群体。
