  • The actual increase in the number of ILI cases is seen in Fiji, Wallis & Futuna, FSM, Kiribati, Tokelau and Marshall Islands.
  • The increase in Cook Islands may reflect an increase in the number of sentinel sites that report.
  • Tuvalu and Vanuatu reported a reduction in the number of ILI cases.
  • The reduction seen for Solomon Islands and Tonga can reflect a reduction in the number of sites reporting ILI for this week.
  • No changes in the number of ILI were reported in French Polynesia (1) and Palau (0)
  • There are no reports available from American Samoa, Western Samoa, Guam, CNMI, Nauru, New Caledonia, Niue, and PNG for this week.

Surveillance figures are not intended to capture all state cases but to illustrate trends over time and are invaluable when the trend goes up beyond the state baseline and then must trigger timely warnings and actions to characterize the actual nature and magnitude of the disease.
