The 2016 Sexually Transmitted and Blood-Borne Infections in Windsor and Essex County report, as prepared by the Windsor-Essex County Health Unit, provides insight into the burden of reportable sexually transmitted and blood-borne infections (STBBIs) in Windsor-Essex County during the previous ten year period of 2005 to 2014. The key findings of this report are described below:

  • Adolescents and young adults (those aged 15-29 years old) accounted for 72% of all STBBIs and were over 10-times more likely to have an STBBI than the rest of the Windsor-Essex County population.
  • Chlamydial infections are the most common reportable disease (accounting for 73% of all STBBIs) in Windsor-Essex County; there is an average of 720 chlamydial infections annually in the region and the number of cases has increased by 48% since 2005.
