Fever, vomiting, and egg-flake soup-like stools are the “gold standard” of autumn diarrhea. The first 1-2 days of the disease are dominated by fever and vomiting, and later diarrhea appears without obvious mucus and pus and blood, and there are many times of diarrhea, as few as five or six times a day, and as many as ten or twenty times a day. The duration of the disease is roughly 3 to 7 days. It is recommended that routine stool tests be performed. Children with mild symptoms of fall diarrhea should only take oral medications: first, montelukast (Bicil, Simethicone) intestinal mucosal protector, second, probiotic supplementation to help restore intestinal flora, and third, oral rehydration solution salt III to prevent dehydration. Dietary considerations: infants can continue to breastfeed or low lactose milk powder (diarrhea milk powder) feeding, eat less and more meals; young children: encourage more water, diet above except greasy, tea or coffee, high sugar drinks, other than a small number of meals can be eaten; but many young children will be delayed for two to three weeks, diarrhea situation has not been improved. The reason for this is that a viral infection causing diarrhea can affect the lactase enzyme in the villi of the small intestine. If the intestinal lactase recovers quickly, the diarrhea can slowly heal; while if it is a child with heavy damage to the small intestine, lactase recovers slowly, resulting in a bad delay. Prevention: 1, hand hygiene, adults and children’s hands should be washed frequently with soap. 2, heard that others or other children have diarrhea to avoid contact. 3, reduce the number of babies taken to crowded places and group meals. 4, food and water should be clean and hygienic. 5, nutrition should be balanced, not picky, not partial food to reduce illness. What are the conditions that require hospital consultation: children who are not well and have severe abdominal pain and crying; increased number of stools or large amount of diarrhea; inability to eat normally; frequent vomiting, inability to give oral medication; high fever (>38℃ for babies within three months, >39℃ for babies over three months); obvious thirst, sunken eyes, irritability, depression, little or no urine; blood in stool and other symptoms must be promptly sent to the doctor. Special note: many clinics give oral administration of small white pills or crushed into powder form, the child’s diarrhea will be reduced or diarrhea will stop, but may appear vomiting, fever, drowsiness, depression phenomenon, need to immediately seek medical attention. This may be due to diphenoxylate poisoning.
