Key Points

Gonococcal Infections

• In 2009, the number of gonococcal infections reported by the Rénago network showed a sharp increase, observed overall as well as for both sexes. This increase is confirmed for laboratories that have consistently participated over the past three years for both sexes (+26% among men and +33% among women between 2008 and 2009). The accelerated rise in gonococcal infections is observed across all regions, albeit with a time lag: this increase occurred earlier in Île-de-France (+37% between 2006 and 2007) than in other regions (+41% between 2008 and 2009).

Syphilis

• Since the rollout of regional STI surveillance in 2007—which is set to continue—the number of sites participating in RésIST has increased. At the same time, the number of reported syphilis cases first increased in 2007 and then decreased over the past two years. These trends are confirmed in sites with consistent participation over the past three years, in Île-de-France and in other regions.

Chlamydia Infections

• The number of tests performed and the number of diagnoses of Chlamydia trachomatis infection increased in 2009. The number of diagnoses rose by 19% among men and 25% among women between 2008 and 2009 among the 56 laboratories that participated regularly from 2007 to 2009.

Rectal Lymphogranuloma Venereum (LGV)

• After a steady increase through 2008 (n=191), the number of LGV cases reported in the surveillance system declined in 2009 (n=160), as did the number of non-LGV Chlamydia trachomatis proctitis cases (67 in 2009 vs. 91 in 2008).

• 90% of LGV cases are diagnosed in Paris. These are predominantly homosexual men, with more than 80% of cases being co-infected with HIV.
