HI.My 3 years old son is having a diarrhea for a week already. He used to have a high temperature for the first 3 days ( still coughing). He has a watery stool, which contains mucus, undigested food. Sometimes its green, sometimes its dark brown. The stool exam shows MACROSCOPY LIQUID, STOOL RBC 1+, STOOL WBC 2+, STOOL YEAST 1+. Is his resault normal? should I give him any medication? Thank you !
