10 Norovirus Symptoms
Reviewed: Dr. Mera
Symptom #8: Fever
Fever occurs in many conditions, such as viral, parasitic, and bacterial infections. It is the body’s natural way of helping the immune system fight an infection. In a fever, the set point of body temperature increases. The body will also try to conserve heat. Chills (a feeling of coldness) often accompany a fever. The repeated muscle contractions caused by shivering help increase body temperature.
The fever associated with a Norovirus infection is usually low-grade (around 38.9° C). It usually starts abruptly and lasts for 24 to 72 hours.
