That being said, there have been some case reports of rash accompanying flu. A
The article concluded that a rash should be considered an uncommon but existing feature of influenza infection, but that it was substantially lower in adults than children.
One of the reasons people are concerned about flu rash is that it has recently gotten some social media and traditional media attention.
In early 2018, a Nebraska mother posted to social media a picture of her son with hives on his arm. Although he had no traditional flu symptoms, such as fever or runny nose, he tested positive for influenza. The post went viral, being shared hundreds of thousands of times.
In a story about the post, NBC’s Today Show featured Dr. William Schaffner, a professor of preventive medicine at the Vanderbilt University School of Medicine.
After sharing the details of the story with flu experts, Schaffner concluded, “It certainly is unusual. Just a rash alone without any other symptoms…” He suggested, “We’re inclined to believe this was a coincidence.”
Although rashes are not used in the diagnosis of influenza, they might be a very rare flu sign for children.
If you child has flu-like symptoms and has a rash, make an appointment with your child’s pediatrician for treatment suggestions. They can determine if the rash is a sign of the flu or another condition.
If your child has fever and a rash at the same time, call your children’s doctor or seek medical attention right away, particularly if they seem ill.
Before flu season, talk about the flu with your doctor. Be sure to discuss appropriate vaccinations for you and your child.
