Wow, I just had this yesterday. Well it is basically a cold, but I got it because I was at a friends' house and they had cats, and I am allergic to cats... so I kept going but basically colds.

According to the American Lung Association, Smoking is the number one way to get bronchitis; but , thats kind of hard to believe in a child, unless, mom and dad and siblings or aunts and uncles or grandparents smoke around them. Also, it can be a viral infection! Once someone aquires a bronchial infection, they can get one easily the next time they "catch" a cold.
