 How long does a typical fever last in babies?

The duration of a fever in babies can vary depending on the underlying cause. In most cases, a fever is a natural response of the body's immune system to fight off infection. Here are some general guidelines regarding the duration of a typical fever in babies:

1. Viral infections: The most common cause of fever in babies is viral infections, such as the common cold or flu. These fevers usually last for a few days, typically ranging from 3 to 5 days. However, the duration can vary depending on the specific virus and the individual baby's immune response.

2. Bacterial infections: Fevers caused by bacterial infections, such as urinary tract infections or ear infections, may persist longer than viral fevers. With appropriate antibiotic treatment, the fever should start to subside within 24 to 48 hours. If the fever persists or worsens despite treatment, it's important to consult a healthcare professional.

3. Teething: Some babies may experience low-grade fevers while teething. These fevers are usually mild and last for a day or two. It's important to note that teething itself does not typically cause high fevers or prolonged fevers. If the fever is high or persists beyond a couple of days, it may be due to an underlying infection coinciding with the teething process.

4. Immunizations: Vaccinations can occasionally cause low-grade fevers in babies. These fevers are generally short-lived, lasting for 1 to 2 days. However, if the fever is high or accompanied by other concerning symptoms, it's important to consult your healthcare provider.

5. Other underlying conditions: In some cases, a fever in a baby may be due to an underlying condition, such as an inflammatory disorder or an autoimmune disease. The duration of the fever will depend on the specific condition and requires evaluation by a healthcare professional.

It's important to remember that fever is a symptom and not a disease itself. It's the body's way of responding to an infection or illness. If your baby has a fever, it's essential to monitor their overall well-being, including their hydration, activity level, and other symptoms. If you have concerns about your baby's fever or if the fever persists beyond a few days, it's recommended to consult your pediatrician for a proper evaluation and guidance.
