A fever develops in reaction to bacteria or a virus entering the body. To be certain a child has a fever, a thermometer should be used. There are many types on the market which make taking a temperature quick and accurate. Normal body temperature is 98.6^o Fahrenheit (F), by mouth. This temperature normally fluctuates during the day. Your child has a fever if his or her rectal temperature is over 100.4^o F, oral temperature is over 99.5^o F, or armpit temperatures is over 98.6^oF. A fever that lasts for more than three days may be a sign of a more serious illness. Parents should contact their child's doctor if they suspect, or have found that their child has a fever. The doctor will offer advice on what needs to be done to reduce the fever safely. Parents should also note other signs of illness such as loss of appetite, fussiness, sleepiness, chills, and seizures.

It is very important to check with the child's doctor before treating for fever. The correct medication and amount must be based on the child'>s weight and age. Children under age eighteen should not be given aspirin. The use of aspirin to treat children's fever has been linked to the rare but sometimes deadly disease called Reye's Syndrome. Doctors often recommend non-aspirin products like acetaminophen (Tylenol or Tempra), or ibuprofen (Motrin, Advil) to bring down a fever.

Sponging with lukewarm water may also help to reduce a fever. Check with your child's doctor to get advice on whether or not to sponge the child. Encourage your child to drink extra fluids but do not "force fluids". Finally, with a fever, clothing should be kept to a minimum because most heat is lost through the skin.
