Human parainfluenza viruses Virus classification Group: Group V ((-)ssRNA) Order: Mononegavirales Family: Paramyxoviridae Human parainfluenza viruses Classification and external resources ICD-10 B34.8, J12.2, J20.4 ICD-9 480.2 DiseasesDB 30631 MedlinePlus 001370 MeSH D018184
Repeated infection throughout the life of the host is not uncommon. Symptoms of later breakouts include upper respiratory tract illness as in a cold and sore throat. The incubation period of all four serotypes is 1 to 7 days. In immunosuppressed people, such as transplant patients, parainfluenza virus infections can cause severe pneumonia, which can be fatal.
Though no vaccines currently exist, research is underway.
Parainfluenza viruses last only a few hours in the environment and are inactivated by soap and water.
There are four serotypes. These include:
- HPIV-1 (most common cause of croup; also other upper and lower respiratory tract illnesses typical)
- HPIV-2 (causes croup and other upper and lower respiratory tract illnesses)
- HPIV-3 (associated with bronchiolitis and pneumonia)
- HPIV-4 (includes subtypes 4a and 4b)
