Vomiting and fever are considered to be caused by intestinal viral or bacterial infections or local cold, so you can register for the pediatric gastroenterology clinic during normal office hours. If the pediatric department of the hospital is not too large and not too detailed, you can also register for the pediatric clinic. If it is out of normal working hours or if the baby is poor in spirit or has a serious fever, you should see the pediatric emergency room, in which case doctors and nurses will give priority to the baby’s examination. Of course, if vomiting and fever are accompanied by other clinical symptoms, such as febrile convulsions and seizures, you should see the pediatric neurology clinic. If there is cough, shortness of breath or shortness of breath, you should see the pediatric respiratory clinic.
