issue of Respiration, Gencay et al. [1] used serology for a panel of 8 common human viruses (adenovirus, enterovirus, influenza viruses A and B, parainfluenza viruses 1, 2 and 3, and respiratory syncytial virus) to document evidence of acute viral infection in patients diagnosed with LRTI. Major endpoints studied included: comparison of the proportion of individuals showing positive viral serol...
BACKGROUND Acute respiratory tract infections (ARTIs) represent a serious global health burden. To date, few reports have addressed the prevalence of respiratory viruses (RVs) in adults with ARTIs attending an emergency department (ED). Therefore, the potential impact of respiratory virus infections on such patients remains unknown. METHODOLOGY/PRINCIPAL FINDINGS To determine the epidemiologi...
Viral infections are common causes of respiratory tract disease in the outpatient setting but much less common in the intensive care unit. However, a finite number of viral agents cause respiratory tract disease in the intensive care unit. Some viruses, such as influenza, respiratory syncytial virus (RSV), cytomegalovirus (CMV), and varicella-zoster virus (VZV), are relatively common. Others, s...
Seasonal epidemics of influenza and respiratory syncytial virus are responsible for significant morbidity and mortality worldwide. Infrequently, novel or reemergent strains of influenza A virus have caused rapid, severe global pandemics resulting in millions of fatalities. The ability to efficiently and accurately detect and differentiate respiratory viruses is paramount for effective treatment...
Recombinant simian varicella viruses expressing respiratory syncytial virus antigens are immunogenic
Respiratory tract infections (RTIs) are the most common diseases globally among children. This study aimed to assess epidemiology of admission-requiring pediatric RTI cases and evaluate effect pathogen type on length hospital stay (LOS) using FilmArray® respiratory panel, a multiplex PCR test. The age-specific distribution seasonality viruses were investigated between March 26, 2018 April 12, 2...
Airway epithelial cells are the primary cell type involved in respiratory viral infection. Upon infection, airway epithelium plays a critical role in host defense against viral infection by contributing to innate and adaptive immune responses. Influenza A virus, rhinovirus, and respiratory syncytial virus (RSV) represent a broad range of human viral pathogens that cause viral pneumonia and indu...
The NanoChip400 system uses multiplex PCR chemistry and electronic microarray detection of influenza A and B viruses; respiratory syncytial viruses A and B; and human parainfluenza virus types 1, 2, and 3. The results obtained with the NanoChip 400 system were compared with those obtained by direct fluorescent-antibody staining (DFA) and real-time PCR with 122 and 130 specimens, respectively. C...
Partial sequences of the G protein gene of 33 isolates from antigenic group B of human respiratory syncytial virus were determined. Phylogenetic analysis indicated that the evolutionary pattern of group B viruses is similar to that previously described for isolates of antigenic group A, including worldwide distribution of related viruses and co-circulation of viruses from different lineages dur...
