What is a viral exanthem?
A virus can affect any organ system in the body and the skin is an organ. Just as a virus can cause a runny nose, cough, or sore throat, it can also cause a rash. It’s just one more symptom.
Viral rashes tend to look like pink dots and happen more often with summertime viruses. The rash can appear anywhere on the body but usually starts on the chest, stomach and back. The rash is usually accompanied by other viral symptoms like fever, diarrhea, runny nose, cough, or sore throat. Sometimes, however they happen without other symptoms on a fussy, cranky child.
How to Treat Viral Exanthem
Usually, there’s nothing to do. These rashes are harmless. Since the rash is part of a virus, it will get better on its own. If it’s not itchy, then there’s no need to apply anything.
If the rash is itchy:
- You can apply an unscented moisturizing cream like Aveno or Eucerin. It’s best to do this after a warm bath while the skin is still damp
- You can apply an over-the-counter 1% hydrocortisone cream up to 3 times per day to the itchy areas
When can my child return to school?
- Once they no longer have a fever, even if the rash is still present
- The rash is not spreading or is starting to go away
- The rash didn’t come from measles or chickenpox. In this case you must get clearance from your child’s primary care provider
