Cold sores are caused by the herpes virus. Many of us already have the cold sore virus dormant in our bodies, and never have a flare up of cold sores. We contracted it as children, as it is a very common virus, and children pick it up easily as they often share food and drinks, and may be less concerned about hand washing and hygiene. Cold sores can be transmitted even when the person does not have a cold sore, though it is less likely to happen then.
remember that you can remove genital warts by surgery, freezing, laser, acid or cream but genital warts can reappear again and again because genital warts appears when your immune system is weak!
I got diagnosed with herpes type 2 about seven years ago, when I was still in college and had a stupid one-night stand. However, Not only was I able to remove all traces of the herpes virus from my system in less than three weeks, but I was also able to start dating again!
