Croupis caused by a number of viruses, all of whom are responsible for the common cold. Some of these viruses include parainfluenza virus type 1 and 2, influenza virus A and B, adenovirus, measles virus and respiratory syncytial virus.

In some instances, croup might also be caused by bacteria such as staphyloccus aureus, streptococcus pneumonia, hemophilus influenza and Moraxella catarrhalis.

What are the signs and symptoms of croup?

The virus which leads to croup affects the respiratory tract causing it to become inflamed and swollen. A person suffering from croup starts off with symptoms of common cold such as fever, sore throat and cough followed by difficulty breathing, hoarseness of voice, stridor which is a creaking noise heard when the individual inhales and signifies an obstruction of the airways. The sufferer also experiences a typical type of cough known as the “barking cough.”
