The chills are definitely caused by fever. It is better to take the temperature at this time to see if it is feverish. If the fever is below 38.5℃, then you can temporarily focus on stopping the diarrhea. As the inflammatory symptoms of abdominal pain and diarrhea disappear, the body temperature will naturally drop to normal. However, if the diarrhea is very severe and the fever reaches 39℃ or more, it is best to go to the hospital for fluid infusion treatment. In addition to rehydration, because the infusion of many fluids also has a certain cooling effect. Also a fever that is too high is treated with antipyretic drugs. A fever of 39 degrees or more is best treated at a hospital.
