• In Oceania, influenza activity remained
low, with a few detections of influenza
A(H3N2), A(H1N1)pdm09, and B viruses
in Australia. In the Pacific Islands, ILI
activity was low overall and broadly
decreased except in French Polynesia,
Samoa, and Tuvalu. RSV activity
decreased in all states across Australia
and remained stable and low in New
Zealand.
