Sexually transmitted and blood-borne infections: Guides for health professionals

The Public Health Agency of Canada (PHAC) provides public health guidance for the prevention and management of sexually transmitted and blood-borne infections (STBBI). PHAC's STBBI guides for healthcare providers and public health professionals outline national recommendations for:

the screening and diagnosis of STBBI
the treatment of sexually transmitted infections (STI) of national public health importance

These guides replace the Canadian Guidelines on Sexually Transmitted Infections. PHAC's STBBI guides do not supersede:

provincial/territorial legislative, regulatory, policy and practice requirements
any professional guidelines that govern the practise of health professionals in their respective jurisdictions, whose recommendations may differ due to local epidemiology or context

Treatment recommendations include indications for the level and quality of evidence.
