†Weeks 23, 30, 33, and 37 data were not available because CDC reported results only through week 20 in the 2005–06 influenza season and began reporting results on week 40 in the 2006–07 influenza season. The last day of the CDC week reports vary by several days from the last day of the survey results reported in Tables 3 and 4.
