Fifth disease. Can I treat this kind of rash? Or will it go away on its own?

Fifth disease, also known as erythema infectiosum, is a viral infection that commonly affects children. It typically starts with cold-like symptoms followed by a red rash on the cheeks that can spread to the arms, legs, and trunk. In most cases, the rash will go away on its own without any specific treatment. It is important to keep the affected individual comfortable and avoid exposing them to heat or sunlight, as this can worsen the rash. Applying a cool compress to the affected areas for short periods of time may help relieve any discomfort.
