Go to the nearest ER or call 9-1-1 if you experience:

• A fever of 104 degrees or above
• Stiff neck
• Confusion or dizziness
• Irritable or erratic behavior

A high fever can be a result of any of the following conditions:

• Infections - may be serious; commonly found in ear, skin, throat, lungs, kidney or bladder
• Cold or flu - typically result in fever at or below 104 degrees in adults
• Bronchitis - inflammation of the lining of your bronchial tubes, which carry air to and from your lungs
• Strep throat - bacterial infection in the throat and/or tonsils, can generate high fevers in children and adults
• Urinary tract infections - typically with low- or moderate-grade fever
• Mononucleosis - is a viral infection, also known as mono, that causes fever, sore throat, and swollen glands

A fever in children and infants is considered to be when the body temperature is 100.4° F or higher.
There are many reasons that your child may be running a fever, such as immunizations,
infections or even just overdressing, especially if they are very young.
It is important to contact the child’s primary care provider (pediatrician) if a fever is present.

Call a doctor if your child is an infant (under three months) and has a temperature taken with
a rectal thermometer of 100.4° F or higher, or if your child is older and has a temperature of 102.2° F.

Also call if the child is older and that temperature is combined with:

• A change of behavior such as not drinking or eating
• Dehydration symptoms such as lack of tears or trips to the bathroom
• Stomach issues such as vomiting or diarrhea
• Has a specific ailment such as ear or throat pain
• 24 hours of the fever and symptoms
• Has a chronic medical condition or a rash

Go to the emergency department if your child has:

• The inability to stop crying
• A rash that resembles bruising
• Seizures
• More difficulty than normal when trying to wake up and trouble moving
• Moderate or severe abdominal pain
• Drooling
• Severe headache or stiff neck
• Blue extremities
• Trouble breathing

This list is not inclusive of all possible medical emergencies. If you are experiencing a medical emergency, call 911 and seek immediate medical attention.
