- Impact –The impact of circulating influenza on society, as measured through the proportion of people with influenza-like illness (ILI) taking time off work, and the burden placed on hospitals with people admitted with influenza, was low.
- Severity –Clinical severity for the 2018 season, as measured through the proportion of patients admitted directly to intensive care unit (ICU), and deaths attributed to influenza, was moderate.
- Virology –Influenza A(H1N1)pdm09 predominated nationally, accounting for an estimated 53% of notified laboratory confirmed cases of influenza for the year to date.
- At-risk populations: Children aged less than 10 years appear were more commonly infected with influenza; however the severity of illness in this population was on par with other age-groups.
- Vaccine effectiveness: Based on preliminary data, vaccinated individuals were 68% less likely to present to a general practitioner (GP) and 58% less likely to be hospitalised due to influenza, when compared to unvaccinated individuals.
