My son 2 two years has diarrhea for the past two days and slight fever this morning at 37.3 could be a bug and how do we treat it?

VIRAL DIARRHEA: As long as there is NO blood/mucous in stool, bad cramp, recent travel, no local endemic factor-, it is viral. Give oral Electrolyte Solution (ORT) 6-8 ounces for each diarrhea, give (BRAT Diet): Banana, Rice, Applesauce, Toast + chicken/soup, cracker, yogurt, more water, minimal juice. Avoid milk as it can worsen diarrhea bc of temporary lactose intolerance. Any worsening see his pediatrician.
