If your baby has a fever caused by a gastrointestinal cold, you should first check your child’s stool routine to see if the gastrointestinal cold is caused by a viral infection or a bacterial infection. If there are elevated white blood cells in the stool routine or blood routine, it may be a bacterial infection causing gastrointestinal flu and fever, and the child needs to be treated with antibiotics, and the baby can be given oral cefixime granules or pediatric cefadroxil. In the case of viral infections, there is often no elevation of white blood cells, which may also be caused by stress etc. in the early stages of the disease, and viruses are generally self-limiting. In addition, if the fever is high, above 38.5°C, fever reduction treatment with ibuprofen suspension or acetaminophen suspension is required. If the fever is below 38.5°C, it can be treated without too much concern. In addition, you need to fast or eat less food for your child, and try to eat simple, light and easy to digest food, such as batter or rice soup.
