how long after exposure to croup do symptoms appear
Croup is an upper respiratory infection that transmits similar to colds or influenza, and generally affects kids up to the age of 5. Once exposed, it can take roughly 2-5 days to develop symptoms.Croup typically can last 3-7 days. I found the information on both the Mayo Clinic website, and on this Healthy Children page: http://www.healthychildren.org/english/tips-tools/symptom-checker/pages/...he Mayo Clinic page has information on how to deal with symptoms (night wheezing, etc.), and when to see the doctor (high fever, or signs of poor oxygenation): http://www.mayoclinic.com/health/croup/DS00312/DSECTION=symptoms.
