Yes, croup is contagious as long it is caused by a virus. Like any contagious germ, viruses that cause croup can spread easily through coughing, sneezing, and respiratory secretions (mucus and droplets from coughing or sneezing).

Do adults get croup? Can adults develop croup?
Although croup is a very common respiratory condition of children but it can also occur in adults. It is generally caused by a virus or allergies, though in rare cases, croup can also be caused by bacterial infection. It causes interrupted breathing patterns during sleep, often leaving the patient feeling fatigued.
The most common cause of croup in adults is the parainfluenza virus (a viral infection). Adults can contract the parainfluenza virus by breathing in airborne infected particles. These contain virus particles, which remain alive on different types of surfaces.
There are several other viruses that can cause croup, in addition to the parainfluenza viruses, such as the adenovirus, respiratory syncytial virus, and measles.
Croup in adults is unusual and rare, but a possible condition. An adult who has developed croup might experience worse symptoms and need a more aggressive treatment than children.
Adults with existing respiratory problems are at greater risk for complications due to the exposure to this virus. This may get spiked in the fall and winter seasons of the year.
How long does croup last in children?
In children, croup generally lasts from several days up to a week, and there is high probability of recurrence. Although the harsh noise heard when your child breathes in (stridor), may only last for 1-2 days but wet cough with mucous may last for 1 or 2 weeks.
You should not stop your child from attending daycare or school merely on the basis of cough that can last for long even after subsiding the characteristic bark sounding cough/ stridor. If the characteristic symptoms of croup are absent though the child may still have cough, they are good to attend school or daycare provided they are not having fever.
