Introduction
Under normal circumstances, after infection with norovirus, a patient's body temperature may rise to 39°C or even 40°C, although the exact temperature varies from person to person, and there is no fixed maximum temperature. Patients infected with norovirus can take medications such as montmorillonite powder, domperidone tablets, and ibuprofen granules under a doctor's guidance.
Generally speaking, there is no defined maximum fever temperature for norovirus infection. After being infected with norovirus, a patient's body temperature may rise to 39°C or even 40°C, but the exact temperature varies among individuals. The detailed explanation is as follows:
The main reason for developing fever after norovirus infection is that the virus activates the immune system upon entering the human body, causing immune cells to release various inflammatory mediators. These mediators act on the body's temperature-regulating center, raising the temperature set point and consequently causing fever. Most patients infected with norovirus may only experience low-grade fever, with body temperatures ranging from 37.5°C to 38°C.
Some patients may develop moderate fever, with temperatures reaching 38.1°C to 39°C. In rare cases, patients may experience high fever, where the temperature may exceed 39°C and even reach 40°C. During the fever process, patients might also experience systemic symptoms such as headache, muscle pain, and fatigue.
Patients infected with norovirus can take medications such as montmorillonite powder, domperidone tablets, and ibuprofen granules as directed by a physician. If a patient develops persistent high fever, severe dehydration, or appears lethargic after norovirus infection, prompt medical attention should be sought for symptomatic and supportive treatment to alleviate symptoms and promote recovery.
