BACKGROUND The highest incidence of childhood acute lower respiratory tract infection (ALRI) is in low- and middle-income countries. Few studies examined whether detection of respiratory viruses predicts ALRI outcomes in these settings. METHODS We conducted prospective cohort and case-control studies of children 1-23 months of age in Botswana. Cases met clinical criteria for pneumonia and wer...
An indirect immunofluorescence respiratory virus panel containing monoclonal antibodies directed against respiratory syncytial virus, parainfluenza virus types 1, 2, and 3, adenovirus, and influenza viruses A and B was used to screen specimens in the nonpeak respiratory syncytial virus seasons in 1989 and 1990. The results indicate that the respiratory virus panel is fairly sensitive (79%) and ...
Respiratory disease has always been present amongst children, but the importance of viruses in its causation is a recent discovery. An historical approach shows the rapid development of our knowledge of the part played by viruses in the aetiology of respiratory infection. The three influenza viruses were the first of the respiratory viruses to be discovered: influenza A by Smith, Andrewes, and ...
The optimal method for identifying respiratory viruses in adults has not been established. The objective of the study was to compare the sensitivities of three sampling methods for this purpose. One thousand participants (mean age, 63.1 +/- 17.8 years) were included. Of these, 550 were patients hospitalized for acute febrile lower respiratory tract infections and 450 were controls. Oropharyngea...
Humans are highly susceptible to infection with respiratory viruses including respiratory syncytial virus (RSV), influenza virus, human metapneumovirus, rhinovirus, coronavirus, and parainfluenza virus. While some viruses simply cause symptoms of the common cold, many respiratory viruses induce severe bronchiolitis, pneumonia, and even death following infection. Despite the immense clinical bur...
