Respiratory syncytial virus (RSV) is a significant cause of respiratory infections in young children. Since 2021, RSV has been a notifiable disease in Australia. However, current surveillance systems focus on hospitalised RSV, with limited surveillance at a community level through primary care clinics. This approach only captures RSV requiring hospitalisation. Less severe illnesses, while not captured, may have significant social and economic impacts including the associated cost of care and absenteeism. The aim of this study is to establish an understanding of the broader burden of RSV in young children in a community setting.

The PATROL (Parents Actively Tracking RSV in Little Ones) project is a prospective longitudinal observational study of RSV and other respiratory viruses in children

Incidence rates of RSV illness and asymptomatic carriage will be calculated and compared with the incidence rate ratios of other respiratory viruses.

The Government of Western Australia Child and Adolescent Health Service Human Research Ethics Committee approved all study materials. Results and findings will be disseminated through manuscripts, conference abstracts and presentations, participant newsletters and appropriate general news media items.
