Sexually Transmitted Infection Risk Awareness Chart

français»

This chart assesses the risk for the transmission of sexually transmitted infections (STIs) when condoms or barriers are not used. Using condoms for anal and vaginal sex and condoms and dental dams for oral sex reduce but do not completely eliminate the risk of contracting an STI.

Chart Key:

High Risk = HR
Some Risk = SR
Theoretical Risk* = TR
No Risk = NR

*Note: Theoretical risk means that in theory a person could contract a given STI through a particular activity but no one has been reported as contracting the STI through that activity. Theoretical risk activities are considered low risk.
