BACKGROUND As the threat of zoonoses and the emergence of pandemic-prone respiratory viruses increases, there is a need to establish baseline information on the incidence of endemic pathogens in countries worldwide. OBJECTIVES To investigate the presence of viruses associated with influenza-like illnesses (ILI) in Uganda. METHODS A cross-sectional study was conducted in which nasopharyngeal...

BACKGROUND Acute respiratory illness (ARI) accounts for a large proportion of all visits to pediatric health facilities. Quantitative real-time polymerase chain reaction (qPCR) analyses allow sensitive detection of viral nucleic acids, but it is not clear to what extent specific viruses contribute to disease because many viruses have been detected in asymptomatic children. Better understanding ...

Respiratory syncytial virus BA genotype has reportedly replaced other group B genotypes worldwide. We report the observation of three group B viruses, all identical in G sequence but lacking the BA duplication, at a coastal district hospital in Kenya in early 2012. This follows a period of six consecutive respiratory syncytial virus (RSV) epidemics with 100% BA dominance among group B isolates....

Because the lung is in constant contact with the environment, infections with respiratory viruses are a common and potentially serious complication of lung transplantation. Infection can cause direct effects, typically manifested as respiratory symptoms and changes in pulmonary function, and indirect effects, such as an enhanced risk of developing chronic allograft rejection. Infections with al...

Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease and a major contributor to the bovine respiratory disease (BRD) complex. BRSV infects the upper and lower respiratory tract and is shed in nasal secretions. The close relatedness of BRSV to human respiratory syncytial virus (HRSV) has allowed researchers to use BRSV and HRSV to elucidate the mechanisms by which th...

conclusions infection with hmpv and rsv are most frequent infections among pediatric patients with respiratory tract symptoms. coinfection with these viruses may exacerbate the clinical symptoms and increase hospitalization rates, especially in children younger than one year old. results the hmpv and rsv were detected in 44 (15.7%) and 84 (30.0%) samples, respectively. coinfection with both vir...

Viruses account for a substantial portion of respiratory illnesses, including pneumonia, in the elderly population. Presently, influenza virus A H3N2 and respiratory syncytial virus are the most commonly identified viral pathogens in older adults with viral pneumonia. As diagnostic tests such as reverse-transcription polymerase chain reaction become more widely used, the relative importance of ...

OBJECTIVE To identify the viruses involved in acute respiratory tract infections and to analyze the rates of hospitalization and death in children on palivizumab prophylaxis. METHODS Prospective cohort of 198 infants up to one year old who were born before 29 weeks of gestational age and infants under two years old with hemodynamically unstable cardiopathy or chronic pulmonary disease who rec...

BACKGROUND Seasonal influenza viruses and respiratory syncytial virus (RSV) are primary causes of acute respiratory tract infections (ARTIs) in children. New respiratory viruses including human metapneumovirus (hMPV), human bocavirus (hBoV), and influenza 2009 A(H1N1) virus have a strong impact on the pediatric population. OBJECTIVES To evaluate epidemiological and clinical features of ARTIs ...

Antibody prevalence against respiratory viruses was noted, as follows: adenovirus (1.3%), influenza A (0.6%), influenza B (12.7%), parainfluenza-1 (22.3%), parainfluenza-2 (2.5%), parainfluenza-3 (18.5%) and respiratory syncytial virus (0.6%). The difference in antibody prevalence between the different virus antigens was statistically significant. High antibody rates to influenza B, parainfluen...
