Every kid gets a fever from time to time, and usually it’s nothing to worry about. But it’s important to know what to do when this happens. Here’s everything you need to know about fevers in children, including when to contact your doctor.
What is a fever?
A fever is a temperature of 100.4º F and higher. The body has several ways to maintain its normal temperature. The organs involved in helping with temperature regulation include the brain, skin, muscle and blood vessels. The body responds to changes in temperature by:
- Increasing or decreasing sweat production.
- Moving blood away from, or closer to, the surface of the skin.
- Getting rid of, or holding on to, water in the body.
- Naturally wanting to seek a cooler or warmer environment.
When your child has a fever, the body works the same way to control the temperature, but it resets its thermostat at a higher temperature. The temperature increases for a number of reasons:
- Chemicals, called cytokines and mediators, are produced in the body in response to an invasion from a microorganism, malignancy, or other intruder.
- The body is making more macrophages, which are cells that go to combat when intruders are present in the body. These cells actually eat-up the invading organism.
- The body is busily trying to produce natural antibodies, which fight infection. These antibodies will recognize the infection next time it tries to invade.
- Many bacteria are enclosed in an overcoat-like membrane. When this membrane is disrupted or broken, the contents that escape can be toxic to the body and stimulate the brain to raise the temperature.
What conditions can cause a fever?
The following conditions can cause a fever:
- Infectious diseases
- Certain medications
- Heat stroke
- Blood transfusion
- Disorders in the brain
What are the benefits of a fever?
A fever actually helps the body destroy its microbial invader. It also stimulates an inflammatory response, which sends all kinds of substances to the area of infection to protect the area, prevent the spread of the invader and start the healing process.
What are the symptoms that my child may have a fever?
Children with fevers may become more uncomfortable as the temperature rises. The following are the most common symptoms of a fever. However, each child may experience symptoms differently. In addition to body temperature greater than 100.4º F, symptoms may include:
- Your child may not be as active or talkative as usual.
- He/she may seem fussier, less hungry and thirstier.
- Your child may feel warm or hot. Remember that even if your child feels like he/she is “burning up,” the actual rectal or oral temperature may not be that high.
The symptoms of a fever may resemble other medical conditions. Always consult your child’s physician for a diagnosis.
When should a fever be treated?
In children, a fever that is equal to or greater than 102.2° F should be treated. Children between the ages of 6 months and 5 years can develop seizures from a high fever (called febrile seizures). If your child does have a febrile seizure, there is a chance that the seizure may occur again, but, usually, children outgrow the febrile seizures. A febrile seizure does not mean your child has epilepsy.
If your child is very uncomfortable with a lower fever, treatment may also be necessary. Treating your child’s fever will not help the body get rid of the infection any quicker, it simply will relieve discomfort associated with fever.
What can I do to decrease my child’s fever?
Specific treatment for a fever will be determined by your physician based on:
- Your child’s age, overall health and medical history.
- Extent of the condition.
- Your child’s tolerance for specific medications, procedures or therapies.
- Expectations for the course of the disease.
- Opinion or preference.
Administer an anti-fever medication, such as acetaminophen or ibuprofen. DO NOT give your child aspirin, as it has been linked to a serious, potentially fatal disease, called Reye syndrome.
Aspirin and the risk of Reye Syndrome in children
Do not give aspirin to a child without first contacting the child’s physician. Aspirin, when given as treatment for children, has been associated with Reye syndrome, a potentially serious or deadly disorder in children. Therefore, pediatricians and other healthcare providers recommend that aspirin (or any medication that contains aspirin) not be used to treat any viral illnesses in children.
Other ways to reduce a fever
- Dress your child lightly. Excess clothing will trap body heat and cause the temperature to rise.
- Encourage your child to drink plenty of fluids, such as juices, soda, punch or popsicles.
- Give your child a lukewarm bath.
- Place cold washcloths over areas of the body where the blood vessels are close to the surface of the skin such as the forehead, wrists and groin.
- Do not use alcohol baths.
