Croup is usually caused by a virus infection, most often a parainfluenza virus. After the third day of symptoms, a patient will begin to clinically improve. The cough may in itself represent a post-viral cough that may persist for weeks. ...Read more

Most daycares and schools require a 24 hour fever free period (without medications). ...Read more
