Help near ringworm!!?

I just found out that one of my closest friend have ringworm, and Im panicking, what can I do to prevent it? how do I know if I already get it? and what about my dogs? please relieve!Help near ringworm!!?
the only article your can do is not come into contact with anything she has- it can be passed fairly easy- ive had it a few times & you would know if you have it- it looks exactly how it sounds- a small red circle & it itches something terrible, if you dont treat it right away itll attain bigger
its okay, its not a matter of natural life or death. :)
in good health if you are that concerned, visit your doctor. Ring worm is completely treatable- you just whip a pill to kill them rotten and that is it. If you own dogs, I would just send for your vet and ask them for some ringworm pills for your dog. They will probably just tender them to you as a precaution.
Like the first person said, kind sure you don't get within any contact with her, because ringworm is outstandingly contagious. It is also very unforced to treat also, and you will know if you have it, trust me. I've have it before. There is some cream you can grasp from your doctor if you do get it.
