The National Surveillance System for Sexually Transmitted Diseases in Italy. STD Surveillance Working Group.

Sexually transmitted diseases (STDs) have increased in importance in recent decades as a result of their wider dissemination, the emergence of new etiologic agents, and changes in sexual behaviors. In Italy, gonorrhea and syphilis are among the 71 diseases for which reporting is legally mandated. Despite these legal requirements, however, considerable underreporting has been documented. The need for more reliable data has led to the establishment of a formal sentinel surveillance system for STDs. The Italian National STD Surveillance Network, which involves 47 reporting centers, was established in 1990. A total of 5,049 patients were reported during the pilot study and the first 6 months of surveillance. For men, the most frequently reported diseases were genital warts and nongonococcal urethritis; for women, the most frequent diagnoses were nonspecific vaginitis and genital warts. The objectives of this system are threefold: a) to obtain a rapid and accurate assessment of the occurrence and spread of STDs; b) to identify trends in disease occurrence; and c) to monitor changes over time by geographic area.
