Noticing a high fever in your infant can be worrying, especially when the cause is unclear. While fever itself is not an illness but a symptom, it often indicates that the body is fighting an infection or responding to other triggers. Some fevers subside on their own, while others may require medical attention. Understanding the common causes of fever in infants can help you take the right steps to ensure your little one receives the care and comfort they need.

This article discusses the causes of high fever in infants.

Causes of high fever in infants

Fever in infants is usually a response to infections or other medical conditions. Here are some common fever causes in infants:

  1. Viral infections

Viral infections, such as the flu, common cold, or respiratory syncytial virus (RSV), are the leading causes of fever in infants. These infections usually resolve on their own within a few days but may require medical attention if the fever persists.

  1. Bacterial infections

Bacterial infections, such as ear infections, pneumonia, and urinary tract infections, can lead to high fever.

  1. Immunisation reactions

Some infants develop a mild to moderate fever after vaccinations, a natural immune response that usually subsides within a day or two. Offering fluids, keeping the baby cool, and using pediatrician-approved fever reducers can help.

  1. Teething

While teething does not cause a high fever, mild temperature spikes can occur due to gum inflammation and increased salivation.

Conclusion

Understanding the causes of high fever in infants empowers parents to take the right steps to protect their child’s health. By monitoring symptoms and seeking medical care when needed, parents can ensure a swift and effective response. Reliable health insurance plans add an extra layer of security during this delicate time, covering medical expenses and reducing financial stress. With timely intervention, proper care, and the right individual health insurance coverage, parents can focus on their child’s recovery with peace of mind.
