Gastrointestinal cold is a very common type of cold clinically, mainly caused by viruses invading the respiratory tract, leading to patients experiencing fever, with generally high body temperature during fever. For patients with fever, since the severity of viral infection varies from person to person, the clinical symptoms of fever and the degree of fever also vary. The specific degree of fever in Celsius depends on the detailed condition of each patient. Typically, the fever in a gastrointestinal cold is above 39°C, and the patient may also experience nausea, vomiting, decreased appetite, nasal congestion, and a runny nose, among other clinical symptoms.
