Volume: 25S1 - May 1999 Sexually Transmitted Diseases in Canada: 1996 Surveillance
Report International Comparisons: Canada and the United StatesComparisons of disease incidence between countries is always problematic and has to be approached cautiously; however, the value of these comparisons lies in highlighting disease-specific trends and in determining the relative success of STD prevention and control activities. Of the three reportable bacterial STD, genital chlamydia (Figure 14) has shown the most diversity in Canadian and U.S. rates since it became reportable in 1991. Syphilis and gonorrhea, on the other hand, have shown reasonably similar international trends in incidence since 1980 (Figures 15 and 16).
