The difference between diarrhea caused by cold and virus lies in the different causes, symptoms and duration of the disease. 1. Different causes: diarrhea caused by cold is due to factors such as eating cold food or cold abdominal stimulation, while diarrhea caused by viruses is commonly caused by viral infections, such as rotavirus. 2. Symptoms are different: diarrhea caused by cold is characterized by unformed stools, occasionally watery stools, and relatively few bowel movements. Virus-induced diarrhea is often characterized by watery stools and more frequent bowel movements, some of which can be more than five times, and may be accompanied by fever. 3. The course of the disease is different: the course of the cold is relatively short, and can be relieved after taking timely measures to keep warm. Virus-induced diarrhea has an incubation period, and the course of the disease is relatively long, usually lasts about five days, and gradually relieved. If diarrhea occurs for a short period of time, it can be observed temporarily. If the diarrhea worsens or lasts for a longer period of time, it is recommended to follow the doctor’s instructions for further examination, to clarify the cause with the help of the doctor, and to carry out targeted treatment or therapy.
