Can norovirus cause recurring fever?

Generally speaking, fever refers to an elevated body temperature. Whether Norovirus infection can cause recurrent fever depends on the specific circumstances. If an individual has a strong immune system or was infected with a small amount of Norovirus, recurrent fever typically does not occur; however, if the individual's immunity is weak, recurrent fever may appear. If discomfort occurs, timely medical attention is recommended. Detailed analysis is as follows:

If the patient's immune system is strong or the amount of Norovirus infection is small, the immune system can rapidly and effectively eliminate the virus, and the inflammatory response can be controlled within a short period of time. In such cases, recurrent fever will not occur. The patient may experience only a brief fever at the initial stage of infection, and as the condition improves, body temperature will quickly return to normal and remain stable.

However, if an individual has a weak immune system, recurrent fever may occur. Norovirus infection can cause inflammation in the gastrointestinal tract and other areas. The persistent presence of inflammation continuously releases inflammatory mediators, which can continually affect the body's temperature-regulating center, causing body temperature to rise repeatedly. Especially when the inflammation is not effectively controlled, the possibility of recurrent fever increases, with body temperature fluctuations generally between 38°C and 39°C.

After Norovirus infection, patients should receive timely and effective symptomatic treatment and care, such as maintaining internal stability by replenishing fluids and electrolytes, and using medications to alleviate gastrointestinal inflammation, which helps reduce the body's inflammatory response.
