My 16 month old grand daughter feel in a 18 deep by 36 wide fish pond that you purchase at lowes or home depot and set in your landscape. The pump is always running. We picked her up as quick as she feel in, but i am worried about that brain eating parasite that has killed 3 children this month. She appears to be fine, it scared her more than anything. But I am not getting any sleep over this for the last 72 hours. She had a runny nose to begin with Friday and Friday evening is when she fell in. What should I do. Panicking in North Carolina.
