Those are the dumbest things i've ever heard,
there is no way i'm going to go up to someone and say 'I had mono, have you had it? because if so.. I can kiss you now! but if not, i'm going to pass you on this virus that made me want to kill myself for atleast a week!' HAHA, very funny.
I'm sure it's not contageous for 6 months.. hwoever, you can never be sure without seeing a medical specialist. So instead of checking out these sites.. it would probably be a smart idea to go there as welll.
thankyou & gooooooodbye.
