                       This is a summary of current Emergency Department sentinel surveillance (EDSS) data for
                       respiratory viral, gastroenteritis, and varicella presentations. Baselines are calculated from the last
                       two years average number of presentations per week.
                                                                                                                                                                       No. of respiratory

                       There was a slight decrease in the number of respiratory viral presentations to Perth EDs this
                       week. The percentage of respiratory viral presentations admitted to hospital remains stable at
                       5.5%. The majority of cases were seen in children aged 1 to 4 years olds (54%: 188/345) and
                       infants aged less than 1 year old (28%: 98/345).
