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). A blood borne infection is transmitted through contact with infected blood.

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
