Volume: 26S6 - October 2000 1998/1999 Canadian Sexually Transmitted Diseases (STD) Surveillance Report IntroductionSince the previous Canadian STD annual report(1) there have been some notable changes in the trends of STD in Canada. In 1998 there were increases in all the national notifiable STDs - genital chlamydia, gonorrhea, and infectious syphilis. The use of nucleic acid amplification techniques (NAAT) for testing for chlamydia and gonorrhea has become widespread in Canada over the last 2 years. Since 1997, all provinces/territories except one used NAAT at least sometimes for testing for chlamydia, and all but three for gonorrhea. It was anticipated that widespread use of NAAT would increase case-finding of STD, especially among males, and this appears to be the case. In 1999, reported chlamydia, gonococcal and infectious syphilis cases accounted for 44% of all notifiable diseases reported to Health Canada (Figure 1).
