A sexually transmitted infection (STI) is an infection that can be transmitted from one person to another through sexual contact (exchange of semen, vaginal fluid, blood or other fluids) including oral sex.

Blood borne infections (BBI) are transmitted by contact with contaminated blood.  Some infections (for example HIV, hepatitis B and hepatitis C) may be transmitted through both sexual and blood borne transmission routes
