Parainfluenza is an infectious disease caused by human parainfluenza viruses. It typically presents with symptoms of the common cold; fever, runny nose and cough. There may also be a sore throat, sneezing, wheezing, ear pain, irritability and poor appetite.
Spread occurs when an infected person is in close contact with another person, from the air by coughs and sneezes, or via contaminated surfaces. It can spread to the larynx and trachea to cause croup. Other complications include bronchitis, bronchiolitis and pneumonia.
There is no vaccine for parainfluenza. Treatment is symptomatic and supportive. The primary methods of prevention are handwashing, not touching the eyes, nose or mouth with unwashed hands, and staying away from sick people.
