Oct 19, 2024

Addressing the Resurgence of Syphilis in Canada

Key Points

  • Increase in syphilis incidence in Canada and worldwide.
  • High-risk behaviors: unprotected sex, multiple partners, substance-associated risky sex.
  • Multisector approach required: education, clinical suspicion, detailed surveillance, rapid testing, discreet screening, addressing social determinants of health.

Epidemiology and Risk Factors

  • Cyclic Nature: Syphilis shows cycles of infection due to changing behaviors and partial immunity.
  • High-Risk Populations: Includes gay and bisexual men (gbMSM), women (notably congenital syphilis cases), and substance users.
  • Dating Apps: Increased use linked to risky sexual behaviors across all orientations.
  • PrEP and Condom Use: PrEP use in gbMSM reduces HIV fears but also condom use, increasing STI risks.
  • Substance Use: Methamphetamine and other drug use associated with risky behaviors.

Demographic Shifts

  • Rise in syphilis among middle-aged adults (40-59 years), linked to social changes and erectile dysfunction treatments.

Data and Surveillance Challenges

  • Lack of Comprehensive Data: Canada lacks timely national STI data, impacting intervention.
  • Missing Ethnicity and Orientation Data: Impedes targeted interventions due to stigma concerns.

Testing and Screening

  • High Clinical Suspicion: Syphilis mimics other conditions; regular screening advised for high-risk groups.
  • Web-Based Testing: Piloted in British Columbia; could enhance screening access.

Educational and Testing Initiatives

  • Education Campaigns: Need for accessible education on transmission methods.
  • Remote Access to Testing: Limited in some regions; point-of-care testing under evaluation.

Collaborative Efforts Needed

  • Combined Approach: Public health education, practitioner involvement, rapid testing, and accessible screening essential in controlling syphilis rates.

Conclusion

  • Combating syphilis resurgence requires comprehensive, coordinated public health strategies involving education, surveillance, testing, and addressing social determinants.
