Australian Influenza Surveillance Report - week ending 28 July 2019 (#07/2019)

The Australian Influenza Surveillance Report and Activity Updates are compiled from a number of data sources, which are used to monitor influenza activity and severity in the community. These data sources include laboratory-confirmed notifications to NNDSS; influenza associated hospitalisations; sentinel influenza-like illness (ILI) reporting from general practitioners; ILI-related community level surveys; and sentinel laboratory testing results.

Australian Influenza Surveillance Report No 07 - week ending 28 July 2019

Summary

  • Activity – Currently, influenza and influenza-like illness (ILI) activity is slightly higher than average for this time of year compared to previous years. However, the disparity between this season and previous years has been decreasing over the last few weeks. At the national level, notifications of laboratory-confirmed influenza have decreased in the past fortnight; however, this may be due in some measure to data entry backlogs.
  • Severity – Clinical severity for the season to date, as measured through the proportion of patients admitted directly to ICU, and deaths attributed to influenza, is low.
  • Virology – The majority of confirmed influenza cases reported nationally were influenza A in the year to date (82%) and past fortnight (79%). After an increase in the proportion of cases attributed to influenza B since early May, the proportion has declined in the past month.
