The term “infection” has been judged more adequate than its “disease” counterpart, namely because of the possibility of asymptomatic condition. The appellation “Sexually Transmitted Infection” refers to infections transmissible sexually or by blood exchange. Condom usage might not offer a complete protection whenever sores are located outside of the protected area.

STIs today

STIs are currently on the rise everywhere in Quebec, especially in younger population aged 15 to 24. This last demographic represent 66% of declared cases of chlamydia and 47% of declared cases of gonorrhoea. Girls of that age are the most infected population overall.

It is important to note that there is no specific age requirement for infection: everyone is susceptible.


In Quebec alone, 40 000 people are diagnosed each year with a STI

  • 1 person out of 5 is infected with genital herpes;

  • 3 persons out of 4 will be infected by HPV (Genital Human Papillomavirus) in the course of their lives;

  • Since 1997, there is twice as much declared cases of chlamydia;

  • For the last 10 years, declared cases of gonorrhoea have known a 200% increase.

These figures are inferior to real cases, since they only encompass cases diagnosed by a physician.

Screening test

It is unlikely that you will detect a STI yourself, since most infected parties do not present any symptoms. Asymptomatic infection does not mean no infection at all, and it can still cause harm to one’s health. An infected party can transmit the infection without ever knowing he or she was infected. A screening test brings peace of mind and the preservation of safe health for you and your partner(s).

Screening tests might include a blood-sampling intervention and, if necessary, the sampling of other substances (for example, urine).

Parental consent is not required for patients aged 14 and up.
