But for those with weakened immune systems, like young children or the elderly, RSV can develop into a more severe condition, like bronchitis or pneumonia. Anyone who experiences a cough so severe that it interferes with sleeping, eating and drinking should contact a doctor. Parents should watch for signs of difficulty breathing in young children, according to the CDC.
To prevent RSV, the CDC recommends avoiding close contact with sick people, washing hands often with soap and water, avoiding touching children's faces with unwashed hands and limiting the time children spend in child care centers.
Researchers are currently developing a vaccine for RSV, but none are available yet.
