What to do after you accidentally drink after someone with a cold?

Don't freak out. It's not too common to get cold sores this way. You would have to take a drink with in seconds of some one with a cold sore doing so. The virus that causes cold sores doesn't live on objects for long periods of time, it also doesn't like to live in fluids.

You would be more likely to get a cold sore if you kissed this person on the mouth.
