"Mild" in this context means not severe. So the symptoms may not be as noticeable as if you were really sick and had severe symptoms! Ex: I was sick this past week, but my symptoms were mild, so I rested for a bit and then felt better. Ex: Did you hear Jonathan is sick? I hope his symptoms are mild. He had severe symptoms last time.
