[1] Signs and symptoms may vary from mild to severe, [1] and usually start two to five days after exposure. [2]
In immunosuppressed people, parainfluenza virus infections can cause severe pneumonia, which can be fatal. [19] HPIV-1 and HPIV-2 have been demonstrated to be the principal causative agent behind croup (laryngotracheobronchitis), which is a viral disease of the upper airway and is mainly problematic in children aged 6–48 months of age.
