title: Respiratory syncytial virus infection and immunoprophylaxis for selected high-risk children in Central Australia.
abstract: BACKGROUND
  There are limited data on the epidemiology and viral aetiology of bronchiolitis in Central Australia and respiratory syncytial virus (RSV) immunoprophylaxis in an Australian population.
  
  
  OBJECTIVE
  To (i) determine the incidence and the viral aetiology of bronchiolitis hospitalisations and (ii) report on the usage of RSV immunoprophylaxis in selected high-risk infants and children in Central Australia.
  
  
  METHODS
  A retrospective review was performed of all hospital separations for bronchiolitis for a three-year period, 1998-2000. Respiratory viruses in the nasopharyngeal aspirates were identified from the cases in the year 2000. A combined retrospective chart review and prospective follow up study was undertaken of all the infants and children who received RSV immunoprophylaxis at the Alice Springs Hospital, Central Australia.
  
  
  RESULTS
  Incidence of bronchiolitis hospitalisation in infants for 1998, 1999 and 2000 were 176, 200 and 180 per 1000, respectively. Nine high-risk children had RSV immunoprophylaxis on a total of 46 occasions and there were two mild RSV-related illnesses in them. None had severe lower respiratory tract illness.
  
  
  CONCLUSIONS
  The incidence of bronchiolitis in Central Australia is extremely high. The usage of RSV immunoprophylaxis may be justified in selected high-risk children living in high endemic areas.
