High Fever in Children

For children, fever is considered high if it reaches 101 degrees Fahrenheit. Generally speaking, the younger the child, the quicker the response to a fever should be. Infants under 3 months, for example, should seek medical attention if the fever reaches 100.4 degrees of Fahrenheit. Children 3 months to 3 years should seek medical attention if the fever reaches 102 degrees Fahrenheit.
Oftentimes when children have a fever they aren’t fussy, or visibly uncomfortable. If your child is running a fever but continues to play normally, eat and drink consistently, is awake and aware of their surroundings, and there is no change in skin color or overall appearance, the fever is likely not serious and can run its course.
Serious fever symptoms in children include:
- Seizures
- Lethargy
- Irritability
- Too weak to speak and stand
- Trouble breathing
- Purple or blood-colored dots on the skin
- Trouble swallowing
- Shaking
- Constant crying
The staff was great. They were friendly and efficient with my care. I was in a lot of pain and they got my diagnosis and treatment plan done within an hour and a half. I was discharged within the next hour and able to go home. I appreciate their effort in making me feel better!
