The Hidden RSV Rash You Can’t Ignore: Recognizing How Respiratory Syncytial Virus Alters Skin Symptoms Respiratory Syncytial Virus (RSV) is a common but often underestimated illness, especially in young children, older adults, and immunocompromised individuals. Most people associate RSV with fever, coughing, and difficulty breathing—but what many don’t realize is that RSV can also cause a subtle but critical skin symptom: an often-overlooked rash that may be the body’s invisible warning sign. ### What Is the RSV Rash? The RSV rash typically appears as diffuse, fine red or purple spots on the skin, commonly affecting the arms, legs, and face. Unlike common rashes from allergies or minor infections, this rash tends to appear during the peak of RSV illness—usually 4–6 days after initial symptoms emerge. While it’s not unique to RSV, its sudden onset alongside respiratory distress makes it a key symptom to watch.
