Influenza-like illness data were retrieved from the World Health Organization’s Global Influenza Programme.16 We collated weekly data for Australia from the week starting January 2, 2012 to the week starting December 25, 2023 inclusive. The data described: (1) the weekly number of cases of influenza-like illness; and (2) the weekly number of specimens positive for influenza by subtype (and the number of negative tests). We grouped the influenza specimens into: influenza A subtype not determined; influenza A H3N2; influenza A H1N1 (influenza A H1N1, influenza A H1N1pdm09); influenza B (influenza B Yamagata, influenza B Victoria, influenza B lineage not determined); and negative tests. Negative tests likely reflect individuals infected with other ILI-causing pathogens or other unknown causes which we do not have data to determine.
