Among the parainfluenza viruses include various closely related viruses that cause many respiratory diseases, flu-like infections of up to influenza-like syndromes or pneumonia; Krupp is the most common serious manifestation. The diagnosis is made clinically in general. Treatment is supportive.
Parainfluenza viruses are paramyxoviruses of types 1, 2, 3 and 4. Despite common antigenic structures with cross reactivity, they tend to cause disease of varying severity. The Type 4 has a Antigenkreuzreaktivität with the mumps virus and appears to be a common cause of respiratory diseases.

Despite common antigenic structures with cross reactivity, they tend to cause disease of varying severity. The Type 4 has a Antigenkreuzreaktivität with the mumps virus and appears to be a common cause of respiratory diseases. In nurseries, pediatric wards and schools can cause outbreaks of influenza virus infections. The types 1 and 2 tend to cause epidemics in autumn, with each serotype appears alternately appear every two years. Type 3 is endemic and most children infected <1 year. In the spring, there is an increased incidence. Parainfluenza viruses can cause recurrent infections, but reinfection usually causes only mild disease. Therefore, most infections in immunocompetent adults are asymptomatic or mildly. The most common disease in childhood is a disease of the upper respiratory tract with no or mild fever. Parainfluenza Virus Type 1 likely caused Krupp (Laryngotracheobronchitis- Krupp), mostly in young children aged between 6 months and 36 months. Krupp begins with the usual symptoms of a common cold. Later, fever, a barking cough, hoarseness and stridor develop. Due to obstruction of the upper airways, it may rarely cause a potentially fatal respiratory failure then. Parainfluenza virus type 3 pneumonia and bronchiolitis may cause (bronchiolitis) in young children. These diseases are usually indistinguishable from disease caused by RSV (s. U.) Are caused, run often but less heavy. A specific virological diagnosis is not required. The treatment is symptomatic.
