Transference of energy is a very real thing. Most don't have to touch you to infect you. But the touch is powerful. Energy exchange that occurs through physical contact is instantaneous. The touch can be used to heal through chi energy, your electromagnetic current. That same electromagnetic energy can be lethal as well. When someone dislikes you and they touch you they are delivering a bad current through you. You may feel off, hostile, sad and array of discomforting emotions and have no idea why you're experiencing them. Be careful who you let in your space and who you let touch you.
