Understanding Fevers

A fever is the body’s natural response to infection or inflammation. When the immune system detects harmful pathogens, like bacteria or viruses, it releases chemicals that signal the body to increase its temperature. While a rise in temperature is a positive sign that the body is fighting off the infection, it can be an uncomfortable experience. The concern may increase when a fever is accompanied by other symptoms, including a rash.

A fever can be caused by almost any infection, including but not limited to:

  • Influenza
  • Common cold
  • COVID-19
  • Strep throat
  • UTIs
  • Pneumonia
  • Bronchitis

Types of Rashes Caused By a Fever

A rash that develops while fever is still present can be caused by a range of conditions. Some illnesses that are well-known for causing both a rash and a fever include scarlet fever, measles, mono, shingles, and chickenpox. Fever-related rashes can be triggered by a number of things. The best way to understand the root cause of your condition is to seek a professional diagnosis. Rashes can vary in appearance and severity, making it crucial to receive medical advice if other concerning symptoms are also present.

While anyone can experience a fever-related rash, it’s most commonly seen in children. Skin rashes are extremely common for infants and young children. These skin rashes can vary in shape and size, though they typically appear as blotchy red spots. It can be difficult to detect the  specific virus causing your child’s rash, so be sure to seek immediate medical care for a full evaluation and treatment.

When To Seek Medical Attention

While many fever-related rashes are harmless and resolve on their own, some rashes can be indicative of a more serious condition. Rashes will generally heal once the underlying condition is treated. It’s always best to consult a healthcare professional for a proper diagnosis and guidance. Timely medical intervention can make all the difference in promoting a speedy recovery and ensuring overall well-being. If you experience any of the symptoms listed below, immediate medical attention is highly recommended:

  • Severe, worsening, or spreading rash
  • Persistent high-grade fever
  • Signs of allergic reaction
  • Difficulty breathing
  • Swollen tongue or lips
