In brief: Croup
Croup is caused by the parainfluenza virus most of the time and causes swelling around the vocal cords in the throat which results in a distinctive cough.
Asthma is a disease of the lungs, and although flare ups are sometimes triggered by viruses they do not cause it. Some viruses, like RSV (respiratory syncytial virus), can cause damage to the lungs resulting in asthma-like symptoms.

In brief: Association
Croup and recurrent croup are associated with bronchial asthma.
Association seems essentially based on the presence of hyperreactive airways and less on the presence of allergic sensitivity, although latter can be considered an aggravating factor.

In brief: Possible association
Croup, especially recurrent croup, can be associated with asthma.
In certain patients, this may related to an allergic trigger, moreso than a virus (the typical cause of croup). Some studies have shown an association between patients with croup and those later diagnosed with asthma. This is not to say that all patients with croup will go on to have asthma.

In brief: Possible
Research over the past several years has suggested that infection with RSV may place that individual at risk for asthma in the future.
