Symptoms Of Listeria

Fever

In its mildest form, the only sign of a listeria infection may be an increased temperature. This change in body temperature will be sudden instead of gradual. A person may feel fine one hour and experience a fever in the next hour. The higher temperature occurs as the immune system becomes more active and works to fight off listeria. If you are an otherwise healthy adult, your temperature may just raise a degree or two, and you might not experience any other symptom. However, if the person infected with listeria is already ill, they may end up dealing with a dangerously high fever. Individuals who are seriously ill with listeria may have a temperature ranging around 103 degrees Fahrenheit.
