4. Low-Grade Fever
A low-grade fever can be a symptom of many different types of illnesses, not just norovirus. However, if you are experiencing some of the other symptoms on this list and you are running a low-grade fever, chances are good that you have contracted the norovirus. Typically if the norovirus is the cause of fever it will stay fairly low grade.
You may experience a spike in temperature for a little while, but for the most part, your fever will stay around 100 degrees Fahrenheit or below. If it goes above 102, it may be something else that is causing your body distress. Aspirin and other fever reducers can help to keep your temperature in check if you can keep them down. You can also try a cool bath or keeping a cool washcloth on your forehead to help keep your temperature down.
