BACKGROUND Human parainfluenza viruses account for a significant proportion of lower respiratory tract infections in children. OBJECTIVE To assess the prevalence of Human parainfluenza viruses as a cause of acute respiratory infection and to compare clinical data for this infection against those of the human respiratory syncytial virus. METHODS A prospective study in children younger than f...

Parainfluenza viruses are important causes of respiratory disease in both children and adults. In particular, they are the major cause of the serious childhood illness croup (laryngotracheobronchitis). The infections produced by parainfluenza viruses are associated with the accumulation of ions and fluid in the respiratory tract. It is not known, however, whether this accumulation is because of...

Aim The study was designed to measure the seroprevalence of viral and bacterial diseases: Infectious bovine rhinotracheitis, bovine viral diarrhea, bovine leukemia, bovine parainfluenza, bovine respiratory syncytial disease, brucellosis, and paratuberculosis among bovine of Himachal Pradesh during the year 2013-2015. Materials and Methods The serum samples were collected from seven districts ...

Human parainfluenza virus (HPIV) is a common cause of upper and lower respiratory illness in infants and young children. In order to classify the HPIV isolates circulating in the central part of Thailand, 650 samples obtained from the lower respiratory tract of patients from two hospital pediatric wards during 2010 to 2013, were analyzed for the presence and types of HPIVs by multiplex semi-nes...

Human-to-primate disease transmission can potentially cause significant morbidity and mortality among wild primate populations and thus constitutes an important conservation issue. Our cross-sectional study examines serological evidence of exposure to human pathogens among wild and pet macaques in Sulawesi. Serum samples taken from 11 pet and 15 wild macaques (Macaca tonkeana) were analyzed for...

The aetiology of Kawasaki disease has not yet been precisely determined. It has been associated with a variety of bacterial and viral agents. Some viruses including human adenovirus, coronavirus, and parainfluenza virus type 3 have been isolated from patients with Kawasaki disease. Clinical presentation of patients with human coronavirus and adenovirus infections mimics Kawasaki disease. In add...

The purpose of this study was to determine the seropositivity circulating viral pathogens and their association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seropositivity. In a cross-sectional design, inhabitants (aged 10–60 years) slum surrounding non-slum areas Dhaka Chattogram Metropolitan cities in Bangladesh were enrolled from October 2020 February 2021. Antibodies SA...

BACKGROUND Human parainfluenza viruses (HPIVs) are common viral causes of community-acquired pneumonia, particularly in children. The four types of HPIV have world-wide distribution; however, limited information exists about the epidemiological profile of HPIV in Latin-America. OBJECTIVE Provide epidemiologic and phylogenetic information about HPIVs that circulated in Latin America between 20...

We have analysed data on respiratory syncytial (RS) and parainfluenza type 3 (PF3) viruses reported to the Communicable Disease Surveillance Centre, London, over the period 1978-87. These confirm the annual winter epidemic of RS virus and show that, in England and Wales, PF3 is a summer infection with regular yearly epidemics.

Parainfluenza virus types 1 to 4 (PIV1 to PIV4) are important human pathogens that cause upper and lower respiratory tract infections, especially in infants and children. PIV1, PIV2, and PIV3 are second only to respiratory syncytial virus as a cause of croup in young children. Although some clinical symptoms are typical of PIVs, etiologic diagnosis always requires detection of infectious virus,...
