5 Questions to Ask When Your Child Has a Fever

Babies aged 3 months and younger with temperatures 100.4 degrees or higher should be evaluated by a physician immediately, says Dr. Jonathan Auth, a CHOC pediatrician.

If the child has a fever and typical cold symptoms, but is otherwise acting well, a fever can last for three to five days before parents ought to seek medical attention, Dr. Auth says.

“After more than five days, you should see a doctor because it increases the risk of other complications,” he says.

A temperature hovering at 102 in a child might be alarming, but Dr. Auth says it’s common for children younger than 5 to spike high temperatures when ill.

In these cases, caregivers ought to work to make the child more comfortable by employing a fever reducer like acetaminophen, which is gentle on the stomach and safe for children of all ages.

When temperatures creep to 104 degrees, a parent should make an appointment with a pediatrician, Dr. Auth says. If a child has a 105-degree fever that doesn’t decrease abruptly with acetaminophen, go to urgent care, he says.

Generally, if a fever accompanies a cold, it will arise at the beginning of the illness, Dr. Auth says.

A fever that appears more than three days after cold symptoms first surfaced, however, could be an indicator of a secondary infection such as pneumonia, ear infection or sinus infection, he says.

In these cases, call the pediatrician.

A high fever early in an illness that is accompanied by body aches or headaches can be an indicator of influenza, Dr. Auth says.

Parents who suspect their child has the influenza should seek medical attention early in the course of the illness. Specific anti-influenza medications can be used to shorten the duration of illness as well as reduce the risk of potential complications and minimize contagiousness.

A flu shot is the best way to protect children against the flu, and is recommended for all children older than 6 months.
