The presenting symptoms include poor feeding, vomiting and fever, which may be followed by diarrhoea. Often the stools are watery and frequent - 10 to 20 times per day - and of large volume in viral diarrhoea. The presentation of blood, mucus and frequent small motions is suggestive of a bacterial cause.
As the condition progresses there is increasing anorexia, vomiting and diarrhoea. The infant becomes lethargic and there may be signs of dehydration with a possible accompanying acidosis.
