Can cold sores be transmitted through kissing?

Cold sores or fever blisters are precisely herpes simplex virus type 1 (HSV-1) that appear as fluid-filled blisters around the lips that can also develop on the chin cheeks or inside the nostrils.

One of the most common ways to contract cold sores is through close personal contact kissing for example. But how does this happen and what can you do to stop it?
