Summary

The flu is a common illness that can cause various symptoms, including cough, chills, fever, and sweats. In some rarer cases, people with the flu may also develop a rash. The rash may present differently in different people, and it is more common in children with the flu than in adults.

Since the flu is a viral infection, treatment often involves resting and drinking lots of fluids, such as water, tea, or clear broth. There is no specific treatment for a flu rash. As someone gets better from the flu, their symptoms, including the rash, will disappear.

If you experience other flu symptoms alongside a rash or severe flu symptoms, you must see your healthcare provider. They can ensure that you are treated appropriately and do not develop complications.
