Parainfluenza is an infectious disease caused by human parainfluenza viruses.[2] It typically presents with symptoms of the common cold; fever, runny nose and cough.[1] There may also be a sore throat, sneezing, wheezing, ear pain, irritability and poor appetite.[1]

Spread occurs when an infected person is in close contact with another person, from the air by coughs and sneezes, or via contaminated surfaces.[3] It can spread to the larynx and trachea to cause croup.[2] Other complications include bronchitis, bronchiolitis and pneumonia.[1]

There is no vaccine for parainfluenza.[4] Treatment is symptomatic and supportive.[2] The primary methods of prevention are handwashing, not touching the eyes, nose or mouth with unwashed hands, and staying away from sick people.[4]
