My daughter has a rash on her chest. sandpaper feel, itchy, with cough and chest congestion, no fever associated. although vague, what could this be?

Scarlet fever ?: Sandpapery texture suggests scarlet fever - which is strep throat with a rash. But the cough and chest congestion make a viral rash more likely. Scarlet fever usually goes with a red sore throat and red lips and tongue, headache, stomach ache and fever. It's diagnosed with a throat culture. Otherwise, if it's a viral rash, there is not so much you can do.

Viral Exanthem: Most likely symptoms are related to viral illness but if she starts having a fever and sore throat then it could be scarlet fever related to Streptococcal infection. Finally the two symptoms could be unrelated with a common cold and dry winter skin or skin irritation from an agent contacting her skin.
