Influenza-like Illness (ILI)

PSSS, EPI - WK 28, 2022 Influenza-like Illness (ILI) cases compared to WK 27, 2022 ILI cases are as tabulated as below for comparison. For an added perspective on the figures and trends percentage, country sentinel sites reporting for WKs 27 & 28 are also shown. Please refer Seasonal Influenza for regional updates

  • Actual increase in the number of ILI cases is seen in Samoa, Palau, Kiribati, Wallis & Futuna, Pitcairn Islands, Cook Islands and RMI for the week.

  • A reduction of ILI cases were seen in Fiji and Solomon Islands. The decrease seen in New Caledonia and Vanuatu may be due to the increased number of sites reported for the week.

  • No changes in ILI numbers from CNMI for the week.

  • No reports were available from French Polynesia, FSM, Tuvalu, Tokelau, Tonga, and Niue for the week. American Samoa, Guam and Nauru have not participated in the surveillance.

  • Surveillance figures are not intended to capture all country cases but to describe trends over time and are invaluable when trends rise beyond country baselines which should then trigger alerts and timely actions to characterize the actual nature and magnitude of the disease.

  • Influenza A and B in Samoa: As of 12th July 2022, the Pacific Epidemic and Emerging disease alerts map marked a red alert for Samoa for influenza A and B after increasing ILI was seen in outpatients and laboratory confirmed cases. The Ministry of Health has issued a second warning for influenza virus through the public media. The increase in cases of the influenza have been detected since June and compared with the past two years. Further verification will be provided by health authorities. Source
