What is fever in a newborn?

An average body temperature for a newborn is between 36°C and 37.2°C. A temperature higher than 38°C is considered a fever and should be taken seriously. Newborns have an underdeveloped immune system, making them more vulnerable to infections. Fever in a newborn can be a sign of a severe illness, such as sepsis or meningitis.

 

Symptoms that may accompany fever in a newborn

In addition to an elevated body temperature, other symptoms that may be seen include:

  • Flushed skin or sweating
  • Irritability or fussiness
  • Decreased appetite
  • Rapid breathing or shortness of breath
  • Sleepiness or lethargy
  • Vomiting or diarrhea
  • Seizures

Seek medical attention immediately if a newborn has any of these symptoms, with or without fever.

  • Other medical conditions: Some medical conditions, such as a urinary tract infection, can cause a fever in newborns.
