Fever in children is common and is usually not an emergency.- However, if your child has a temperature over 100.4 °F for three consecutive days, you should consider consulting a medical professiional.
- You should also seek medical aid if your child has a fever and is experiencing symptoms including vomiting, diarrhea, confusion, and if the fever lasts for more than three consecutive days.
Fever in children accounts for the$4 of pediatrician and family physician consultations. It is most commonly$4 by infections since body temperature increases when the immune system$4 off bacteria and viruses.
A child's temperature that exceeds$4 is considered a fever.
"For most children, having a fever is not an emergency and it's not dangerous for a child to have a high temperature," says$4, Pediatric Hospitalist at Texas Children's Hospital.
However, there are a couple of important caveats to Masciale's advice:
- Call your
health care provider $4 when an infant younger than 3 months develops a fever over 100.4°. - Children over 3 months with a temperature over 100.4 °F may need medical attention $4 if it lasts more than three days.

How to take your child's temperature
A parent can take their child's temperature in$4, including:
- $4 (forehead)
- Oral (mouth)
- Tympanic (ear)
- Axillary (armpit)
- Rectal (anus)
Different thermometers have different temperature ranges for $4. So always check the directions on the packaging for how to interpret an accurate reading. Here's $4 of temperatures that indicate a high fever and should be given medical care:
| Thermometer type | Children less than 3 months | Children older than 3 months |
Temporal | >100.4 °F | >102.5 °F |
| Oral | N/A | >102 °F |
| Tympanic | >100.4 °F | >101.5 °F |
| Axillary | >100.4 °F | >101.5 °F |
| Rectal | >100.4 °F | >102.5 °F |
Though parents and children $4 it, rectal thermometry is the$4 way to measure$4. "I recommend this method for children less than 3-4 months old because it's especially important to get an accurate temperature in this age group," says Masciale.
The accuracy of oral thermometry$4 as children become more cooperative. Parents who don't have a thermometer may often check for fever by feeling the forehead with the back of their hand, but according to Masciale, this is $4.
Running around playing or dressing warmly may$4 body temperature, so evaluating through touch can$4 the presence of fever. To be completely certain, use a thermometer, and if you're fresh out $4 that may indicate the presence of an infection.
What causes fever in children?
A fever is a body's way of $4 infection. At a higher temperature, some parts of the immune system$4 and some bacteria and viruses$4, says$4, Assistant Professor of Pediatrics at Baylor College of Medicine.
Many common conditions can cause a fever, but$4 come from viral infections, such as:
- Common cold: A fever will be $4 and can be$4 by cough, hoarseness, and nasal discharge.
- Chickenpox: Aside from the distinctive chickenpox rash, symptoms also$4 loss of appetite, headache, and tiredness.
- Roseola: In some cases,$4 like rashes and swollen eyelids are too mild to be easily recognized.
- Flu: Other than the fever, the child may also$4 vomiting, diarrhea, and fatigue.
Some of the common causes of fever in children come from bacterial infections as well, which includes:
- Urinary tract infections (UTIs): An unexplained fever might be the$4 of UTI in children up to two years old. Specific signs like dysuria, cloudy urine, and a more frequent need to urinate appear after the age of two.
- Strep throat: The symptoms$4 sore throat, painful swallowing, abdominal pain, headache, and sometimes nausea.
- Acute otitis media (AOM) or a middle ear infection: Fever with ear pain, difficulty sleeping, and constant ear tugging may$4 an ear infection.
- Conjunctivitis or pink eye: Pink eye can be caused by a viral or bacterial infection. The infection is usually$4 by redness, itchiness, discharge, and possible tearing in one or both eyes.
The$4 causes of fever are dehydration, teething, or sunburn. In rare cases, pneumonia, metabolic diseases, and allergic reactions to food or medications can also$4 in a fever.
"Fever is just a symptom and actually one way your child's body is working to cure itself," says Hess. "Treat your child and not the temperature."
In about$4 of cases of fever, the cause cannot be conclusively determined.
Treating your child's fever
There are different$4 to reduce a child's fever. Experts recommend that feverish children drink plenty of fluids because they get dehydrated$4. Wearing lightweight clothing can also have a$4.
Parents may give their child some$4 to relieve their symptoms, such as:
- Tylenol: Acetaminophen, the active ingredient in Tylenol, reduces fever, sore throat, aches, and pain. It is only for children$4 unless otherwise cleared by the doctor.
- Advil or Motrin: Ibuprofen relieves headaches and reduces fever, sore throat, aches, and pain. Do not give ibuprofen to children$4.
Common home remedies, like dabbing a damp cloth on the child, is not proven to reduce fever, but it can still help make them more comfortable.
However, Hess says to $4 because, "this will induce the body to start shivering as the brain fights to bring the temperature back up," says Hess. And shivering can actually $4 even more, worsening symptoms.
When to see a doctor
Fevers in children usually go away$4. However, Masciale says that a child is at$4 of getting infected by more serious bacteria if they haven't received their standard $4. There's also the risk of a secondary infection. For example, the flu can cause secondary infections like $4.
According to her, you should call your healthcare provider and discuss scheduling an appointment if your child is experiencing the following$4:
- Vomiting
- Diarrhea
- Confusion
- Severe pain in the body
- $4, or convulsions triggered by fever
- A fever that exceeds three days
- A persistent fever that comes and goes
- Showing signs of dehydration like urinating less often, having a dry mouth, or having no tears when crying
"It's important to get checked out by a doctor to make sure there isn't something more serious going on that their body cannot fight off on its own," says Masciale.
Experts recommend going straight to the emergency room (ER) if the child is struggling to breathe, not waking up, or if they are younger than 3 months.
"Depending on the situation, the doctor will likely take a full set of vital signs, talk to you, and examine your child," says Hess. "But know that the moment your child gets to the ER, they are$4."
Insider's takeaway
If you're worried that your child may have a fever, the most conclusive way to know for sure is by measuring their temperature using a thermometer.
Bacterial and viral infections often cause fevers in children, so discuss treatment options with a healthcare provider. If their symptoms worsen, see a doctor immediately.
"In most cases, the height of the fever isn't important," says Hess. The fever duration and clinical condition is $4 in assessing illness severity.
