As a parent, it's hard not to be concerned when your child
has a fever. But, understanding what a fever is, why it's a
sign that your child's immune system is working, how to
recognize it and when to call your pediatrician may help
alleviate the inevitable anxiety most parents feel when
their child gets a fever.
What Is a Fever?
A fever is not an illness unto itself. It is a symptom of sickness and can be a positive sign that the
body is fighting infection. However, a fever can make your child uncomfortable1 so it's important to know
what options you have to help lower your child's fever and make him or her feel better.
What Causes a Fever?
A fever is generally caused by:
- Viral infections such as the flu and sometimes a cold, or
- Bacterial infections such as strep throat or an ear infection
Other causes include:
- Teething, which may slightly increase a child's temperature (not typically higher
than 100°F)
- Immunizations, which may cause a child to have a low-grade fever for one or two days
- Heat exhaustion
- Extreme sunburn
In some cases, a fever may be an indication of something more serious such as chickenpox
or a kidney infection.
How Do You Recognize a Fever?
While every child is different, a child who has a fever will typically show signs of being sick.
Take your child's temperature if you see one or more of the following symptoms:
- Excessive sweating and/or a flushed face or skin
- Dry, hot skin that feels warm to the touch
- Sleepiness
- Unusual breathing or cold symptoms
- Ear pain
- Vomiting
- Poor appetite
- Crankiness
The illness is probably not serious if your child:
- Has a mild fever
- Is still interested in playing
- Is eating and drinking well
- Is alert and smiling at you
- Has a normal skin color
- Looks well when the temperature comes down2
Regardless of your child's symptoms, you should always call the doctor if you are concerned about
the health of your child.
