Pediatrics - Fevers
Fever is a symptom of illness, and it is the body’s way of fighting off infection. While parents often fear fever in their children, it is a healthy response to illness and typically not harmful or life-threatening, unless it is extremely high, as in over 107° F (measured rectally). Most fevers are caused by common infections that are not serious.
CausesThe most common causes of fever in children include viral infections, bacterial infections and immunizations. Toddlers and young children are especially prone to fevers. In fact, many children this age experience 7 to 1 viral infections a year. A common thought among parents is that teething may cause fever, but it does not.
Signs and symptoms of fever may vary according to your child’s age. If your child is too young to speak or verbalize the way he feels physically, the following symptoms may indicate a fever:
- Irritable or fussy
- Quiet or lethargic
- Feel warm or hot
- Decreased appetite
- Changes in sleeping habits
- Rapid breathing
If your child is old enough to express how she feels, she may complain of:
- Body aches
- Not being able to sleep or needing to sleep more
- Decreased appetite
After examining your child, the doctor may order certain tests to determine - or rule out - the cause of fever. The most common tests are urinalysis and blood tests to check for bacterial infections and/or dehydration. A throat culture can diagnose common sore throat conditions such as strep throat. A chest x-ray can help diagnose certain heart, lung and chest conditions. If the doctor suspects meningitis, she will order a lumbar puncture (spinal tap).
To prevent the viruses and bacteria that cause fever, teach your child proper hygiene:
- Make sure your child washes his hands frequently, especially after going to the bathroom and before eating.
- Teach your child to cough or sneeze into a tissue or her elbow and to use a tissue when wiping her nose.
- Tell your child not to share food, cups or utensils with other children.
- Use disposable antibacterial wipes and hand sanitizer in public places where soap and water are not available.
Am I at Risk
Young children are most susceptible to fever, especially those in day care or preschool. Coming in contact with another child who has a viral or bacterial infection is the main risk factor for fever.
Children with high or persistent fevers may experience complications such as:
- Severe dehydration
