Question

Why can't most STIs be transmitted through casual contact with people or contaminated objects?

Answer 1

Because most STD (STI)s are bloodborne diseases, and the sexual contact is close enough to blood contact, or are on the genitals.

Answer 2

Sample Response: Most germs that cause STIs die quickly once they have left the human body. Objects like eating utensils, toilet seats, and swimming pools are generally safe under usual circumstances.
