Tomorow's (week 51) MMWR reportable disease page (last report for 2011) has no updates on novel influenza (remains at 8 reported in 2011, which includes 6 cases infected in 2011).

http://wonder.cdc.gov/mmwr/mmwr_reps.as ... wr_table=1Last entries were cases from Maine in October. The following cases have yet to be reported:
Indiana/10/2011 (October) H3N2pdm11 (H3N2v)
Iowa/07/2011 (November) H3N2pdm11 (H3N2v)
Iowa/08/2011 (November) H3N2pdm11 (H3N2v)
Iowa/09/2011 (November) H3N2pdm11 (H3N2v)
West Virginia/06/2011 (December) trH3N2 (H3N2v)
West Virginia/07/2011 (December) trH3N2 (H3N2v)
Minnesota/19/2011 (December) trH1N2 (H1N2v)
Wisconsin/28/2011 (December) trH1N1 (H1N1v)
Northern California (December) trH3N2/H3N2pdm11 (H3N2v)
IHR regulations require reporting within 48 hours of lab confirmation. All of the above (with the possible exception of Northern California) have been lab confirmed (and likely reported to the WHO website on notifiable diseases), but the lag in CDC MMWR reporting remains curious.
Tomorrow's MMWR also has week 52 update, which also does NOT update data on novel infleunza cases in 2011
