Oh my sweet, simple child...90% of the world has herpes (Bee IS correct). Out of that 90%, it's estimated that a whopping 8% of people get any kind of outbreak at all; some monthly, some yearly, and some every 5-10 years or so. People like to treat this virus like it's something dirty and disgusting, when in reality, it's no different than you getting a cold or flu and that virus staying in you.
SO what? The stigma attached to herpes is absolutely ridiculous when it's rarer to NOT have the virus at all. It's common, you probably HAVE it, have BEEN having it, and will never get an outbreak in your life. There is seriously nothing to freak out over at all. Even doctors couldn't care less about herpes. They check you out, tell you what you have, give you meds if it's severe, give you treatment options at home if it's not severe, and send you on your way. Cold sores are VERY common. They're gone in 2-3 weeks. Get over it.
AND, even if your friend's case is severe, that in no way means that *should* you contract it, that it will be severe for you. Herpes is a virus and the strength and occurrence of outbreaks all has to do with your immune system. She has a weak immune system if she's on meds for it. Stop trying to make a normal disease that everyone has abnormal.
