Ear infections cause pain, swelling, and sometimes fever or discharge. Most affect the middle ear and can be treated effectively when caught early.
It is not unusual to experience a fever during an ear infection. Ear infections can be caused by either bacteria or viruses, and the immune system's response to either can trigger a fever.
Fever is the body raising its temperature to create a less hospitable environment for infection. For infants under three months, any fever of 100.4°F or higher warrants immediate medical attention.
For older children and adults, a fever above 103°F is generally the threshold for concern, though any fever accompanied by vomiting, diarrhea, or severe pain should be evaluated by a doctor regardless of temperature. The best way to treat a low fever is to stay hydrated and get plenty of rest.
