  • What proportion of children with WHO-defined severe pneumonia (PNG classification of moderate or severe pneumonia) had respiratory viruses isolated?
  • What were the proportions of children with severe pneumonia who had Human Metapneumovirus (HMPV), Influenza A and RSV
  • What proportion of children with RSV had chest x-ray changes of pneumonia?
  • What was the relationship of RSV and other viruses to weather and seasons?
  • What are the limitations of this study, and what are the considerations in applying the study results in PNG?
