BACKGROUND Acute bronchiolitis frequently causes infant hospitalization. Studies on different viruses or viral genomic load and disease severity or treatment effect have had conflicting results. We aimed to investigate whether the presence or concentration of individual or multiple viruses were associated with disease severity in acute bronchiolitis and to evaluate whether detected viruses modi...

BACKGROUND Unlike influenza viruses, little is known about the prevalence and seasonality of other respiratory viruses because laboratory surveillance for non-influenza respiratory viruses is not well developed or supported in China and other resource-limited countries. We studied the interference between seasonal epidemics of influenza viruses and five other common viruses that cause respirato...

DNA chips represent a major advance in microbiology laboratories, enabling the detection of a wide range of possible pathogens using a single test. This study compared a multiplex reverse transcription-PCR combined with DNA chip hybridization (ProDect BCS RV chip; bcs Biotech) with the indirect immunofluorescence test commonly used to detect respiratory viruses. A total of 39 respiratory viruse...

Acute respiratory tract infection is a leading cause of significant morbidity worldwide. It is one of the most important causes of mortality in infants and young children and disabilityadjusted life years lost in developing countries (WHO 2009). Although some viruses, such as influenza virus, respiratory syncytial virus and human adenovirus are responsible for most acute respiratory tract infec...

Background: Types of viral strains play an important role in developing respiratory infections children, but what are prominent each community and how they distributed both sexes different ages is not yet fully understood many countries, such as Iran. Objectives: We aimed to determine the prevalence caused by types viruses children with symptoms admitted a referral children's hospital Methods: ...

Viruses account for the majority of the acute respiratory tract infections (ARIs) globally with a mortality exceeding 4 million deaths per year. The most commonly encountered viruses, in order of frequency, include influenza, respiratory syncytial virus, parainfluenza and adenovirus. Current evidence suggests that the major mode of transmission of ARls is through large droplets, but transmissio...

BACKGROUND Previous ecological studies have shown a temporal and spatial association between influenza epidemics and meningococcal disease (MNG); however, none have examined more than two respiratory viruses. METHODS Data were obtained in Chile between 2000 and 2005 on confirmed cases of MNG and all confirmed cases of respiratory viruses (influenza A and B; parainfluenza; adenovirus; and resp...

Occurrence of different viruses in acute respiratory tract infections of Nigerian children was examined. Respiratory swabs were collected from 246 children referred to hospital clinics because of acute respiratory symptoms from February through May 2009. Validated real-time RT-PCR techniques revealed nucleic acids of at least one virus group in 189 specimens (77%). Human rhinoviruses and parain...

Over 200 strains of respiratory viruses cause a variety of human infections ranging from common cold to life-threatening pneumonia. Respiratory viruses implicated in this study are respiratory syncytial viruses (RSV), adenovirus, influenza viruses and parainfluenza viruses. The objective of this study is to determine the epidemiology of respiratory viruses in paediatric patients with lower resp...

This study reported a case of rhinosinusitis for Respiratory Syncytial Virus in Intensive Care Unit patient. The settings were Intensive Care Unit at Hospital das Clínicas, University of São Paulo Medical School, São Paulo, Brazil. One female HIV-infected patient with respiratory failure and circulatory shock due to splenic and renal abscesses, who developed rhinosinusitis caused by RSV and bac...
