  5. Since August 1, 2014, "Complicated Influenza" has been renamed as "Severe Complicated Influenza". The case definition for "Severe Complicated Influenza" has also been changed since then. Only cases of influenza with complications and have been admitted to ICU or died are required to be reported.
  6. Yearly statistical data must be compiled using 'Year' or 'Year-Month' as the statistical units, with an appropriate data period selected. The 'Year-Week' unit should be used for weekly statistical data. Since weeks may span across different years, the total sum of all weekly data in a year does not equal the yearly statistical data.
