Answer:
Explanation:
In acute cases, bronchitis isn't too dangerous and will usually go away by itself. When symptoms last for longer - usually more than three months - it develops into a more chronic condition which can damage the lungs, causing the tiny air sacs inside the lungs to fill up with fluid.
