Fever: What You Need to Know
Are fevers dangerous?
Not usually. A fever is the body’s natural response to an infection caused by virus or bacteria. Fever occurs commonly with mild, viral illnesses and may come and go for a few days (even with the use of acetaminophen such as Tylenol). The child may feel worse when the fever is present and better when the fever is down. This is normal. Children with a fever may not have much of an appetite, but they tend to eat more when they are feeling better. Fluid intake is important as small children can become dehydrated with fever. Oral re-hydrating solutions are not recommended unless the child is vomiting or has diarrhea.
What about fever seizures?
About 4 percent of all children with fevers will have associated seizures. These are most common in children under the age of 5. A seizure with fever may happen suddenly and is quite frightening. The seizure generally does not last long (one to 10 minutes) and resolves without treatment. The child will feel sleepy afterwards and may not remember what happened. Some children will experience fever seizures more than once in early childhood. It is uncommon to have long-term problems with fever seizures. Do not attempt to put anything in the child’s mouth while the child is experiencing a seizure of any kind and make sure the child is safe from falling or injury. Never leave a child unattended during a seizure.
What number on the thermometer indicates a real fever?
It is generally accepted that a temperature of 100.4° F (38°C) or more in a young infant or 101°F in older infants and children is a fever no matter what method you use to take it. Other factors including exercise, time of day (late afternoon), teething and environmental temperature (caused by a hot room, hot day or a bundled up child) can cause mild elevations in body temperature which do not represent a true fever.
What other symptoms indicate fever?
A child may experience flushing, fatigue, irritability and a decreased appetite. You may be able to tell if a child has a fever by touching his or her forehead or abdomen, but taking the temperature is the only way to know for sure.
