Viral exanthems are skin rashes caused by viral infections, commonly seen in children. These rashes often appear alongside other symptoms like fever, cough, or sore throat. Some well-known viral exanthems include those caused by measles, rubella, and roseola. The rashes usually start on the face or trunk and can spread to other parts of the body. Most viral exanthems are self-limiting, meaning they resolve on their own without treatment. However, it's essential to monitor symptoms and consult a healthcare provider if there are concerns. Vaccination against certain viruses, like measles and rubella, can help prevent these infections and their associated rashes.
