Fever and a rash? What you need to know right now.
A fever and a rash showing up at the same time? It’s never fun when your body surprises you with both. It might seem harmless, but sometimes, a fever paired with a rash could signify something more serious.
Whether you’re an adult or caring for a child, let’s break down what’s happening when these symptoms combine and when you should seek help.
What does it mean when you have a fever and a rash?
When a fever and a rash appear together, it’s a red flag.
Fever means your body is fighting off an infection or inflammation and the rash can indicate a skin reaction to that illness.
But not all fevers with rashes are created equal.
- Infections. Viruses like measles, chickenpox, or even the flu can cause both a fever and rash to strike simultaneously.
- Allergic reactions. Sometimes, your body reacts to medications or allergens with a fever and a rash, especially if you’re sensitive to specific drugs.
- Autoimmune conditions. Diseases like lupus or juvenile arthritis can sometimes present with a fever and a rash as part of a flare-up.
Understanding the cause is essential for knowing how to treat it.
Common causes of fever rashes in adults and children.
A fever rash could be due to a wide range of causes. Some are harmless, while others require quick medical attention.
Here are some common causes:
- Viral infections. Many viral illnesses can cause a generalized rash, which often goes away after a few days. Some specific viruses can cause characteristic rashes such as those with varicella, roseola, and measles.
- Bacterial infections can also cause a rash. Scarlet fever rash is one commonly seen with strep throat infections.
- Heat rash. In children, fever can sometimes cause a heat rash due to overheating.
- Medication reactions. Certain antibiotics, NSAIDs and anti-seizure medications can cause fever rashes as a side effect.
When a fever rash is severe: symptoms you shouldn’t ignore.
Most fever rashes clear up on their own, but sometimes they point to something more dangerous.
Don’t ignore these red flags:
- Purple or bruised-looking rash. A dark, bruised rash alongside a fever could indicate a bleeding disorder, or meningitis, which is a medical emergency.
- Severe headache, neck stiffness, or confusion. These symptoms paired with a rash and fever could also signal meningitis.
- Difficulty breathing. If the rash seems to cause swelling or breathing issues, seek immediate medical care.
- Blisters or peeling skin. This could indicate a more severe drug reaction, like Stevens-Johnson syndrome.
If any of these symptoms are present, you should go to your nearest emergency room right away.
