Your baby has a fever. And you’re worried and wondering what may have caused the fever. Almost all fevers have an infection as a cause. A virus is ten times more spreadable than bacteria.

In case you don’t know, fever is the first sign of an illness. Not a sickness in itself. Fever presents itself when the immune system is fighting an infection. Despite what everyone may think, fever in itself is not dangerous.

What’s dangerous, is the underlying infection. That’s what puts the baby at risk. During the first 24 hours, fever may be the sole indication of the infection.

The beginning of viral symptoms such as a runny nose, cough, and loose stools is delayed. Roseola is the harshest example. Fever may be the sole sign for the first 3 to 5 days. After that, a rash emerges. The most probable cause of silent fever in girls is a bladder infection. Strep throat is also a common reason for the unexplained fever. Fever also occurs after most immunization vaccines shots.

If you treat the fever, that does not mean that the infection will go away. Parents and caregivers should monitor carefully the child for any sign of complication.

Sometimes, healthcare professionals recommend using an electrolyte drink. Signs of a dehydrated baby include: not urinating as often, sunken eyes, chapped lips, dry looking skin.
