The post above isn't too accurate, so I'll chime in.
HSV-1 or cold sores is transmitted through romantic kisses, not from objects or food at this age. It's likely that your roommate is also sick with a cold, hence the name "cold sore", and you got a cold from her, not HSV-1. You probably passed this cold to your boyfriend. You really have no reason to think this is herpes.
Hey Kelly,
Herpes is very contagious, I don't know what to say. I don't know how likely it is to catch coldsore from sharing a burger even a tiny bit. But sharing cups is a sure thing. U do transmit that virus from sharing cups.
It is a social stigma about cold sores. Its really not that big of deal. Its like all of us having a cold. It is a virus. Do not let that get you down. People are starting to learn it is a sickness and nothing like omg that person is nasty cause they have a cold sore.
Hope this helps.
