Epidemiology of parainfluenza virus type 1, 2 and 3 infections based on virus isolation between 2002 and 2011 in Yamagata, Japan.
Summary of "Epidemiology of parainfluenza virus type 1, 2 and 3 infections based on virus isolation between 2002 and 2011 in Yamagata, Japan."
To clarify the epidemiology of viral acute respiratory infections (ARIs), we isolated 305 human parainfluenza virus type 1 (HPIV1), 154 HPIV2 and 574 HPIV3 strains from 16,962 nasopharyngeal swabs obtained between 2002 and 2011 at pediatric clinics in Yamagata, Japan. The total isolation frequency for HPIV1-3 was 6.1%. Unlike HPIV1 infections, HPIV3 showed clear seasonality with yearly outbreaks in the spring-summer season. HPIV2 tended to appear biannually in autumn-winter. Our results suggested that HPIV1-3 should be considered an important causative agent of ARIs in children, although no reliable technique for the laboratory diagnosis of these infections has been established.

Medical and Biotech [MESH] Definitions
Sendai Virus
The type species of RESPIROVIRUS in the subfamily PARAMYXOVIRINAE. It is the murine version of HUMAN PARAINFLUENZA VIRUS 1, distinguished by host range.
Bronchiolitis, Viral
An acute inflammatory disease of the upper RESPIRATORY TRACT, caused by paramyxoviruses, occurring primarily in infants and young children; the viruses most commonly implicated are PARAINFLUENZA VIRUS TYPE 3; RESPIRATORY SYNCYTIAL VIRUS, HUMAN; and METAPNEUMOVIRUS.
Parainfluenza Virus 1, Human
A species of RESPIROVIRUS also called hemadsorption virus 2 (HA2), which causes laryngotracheitis in humans, especially children.
Central Nervous System Infections
Pathogenic infections of the brain, spinal cord, and meninges. DNA VIRUS INFECTIONS; RNA VIRUS INFECTIONS; BACTERIAL INFECTIONS; MYCOPLASMA INFECTIONS; SPIROCHAETALES INFECTIONS; fungal infections; PROTOZOAN INFECTIONS; HELMINTHIASIS; and PRION DISEASES may involve the central nervous system as a primary or secondary process.
Parainfluenza Virus 4, Human
A species of RUBULAVIRUS causing endemic upper respiratory infections in children. It produces only a mild clinical disease and often goes undetected.
