My grandson, 1 1/2-year-old, had high fever of 103 degree with non-stop diarrhea & vomiting, fever subsided on the 2nd day after giving medication, vomiting & diarrhea lasted for another day, stool test result showed cyst of E.H. On the 3rd day, that is today, diarrhea & vomiting also stopped. Taken to a pediatrician on the 2nd day and given antibiotics for 5 days. Is E.H cyst in stool dangerous? What is the cause for it and what is the correct treatment?
