I have a racoon in my yard.

I was just in my backyard and came face to face with a racoon. We stared at each other for about a minute and then it slowly went under my deck. I thought if they are out during the day then that means they are sick. Am I wrong? I don't know if it's living under my deck as this is the first time I've seen it. I'm not sure what I should do as I have a 5 year old and I don't want her outside if the racoon is living there. Any suggestions on how to handle it humanely?
