1 influenza-associated pediatric death; total 4

During week 8 (February 19-25, 2012), influenza activity in the United States increased slightly, but remained relatively low.

U.S. Virologic Surveillance: Of the 3,947 specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories and reported to CDC/Influenza Division, 726 (18.4%) were positive for influenza.
Pneumonia and Influenza (P&I) Mortality Surveillance: The proportion of deaths attributed to P&I was below the epidemic threshold.
Influenza-associated Pediatric Mortality: One influenza-associated pediatric death was reported and was associated with an influenza virus for which the type was not determined.
Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 1.9%, which is below the national baseline of 2.4%. Regions 1, 5, and 7 reported ILI at or above region-specific baseline levels. Three states experienced high ILI activity; 2 states experienced moderate ILI activity; 6 states experienced low ILI activity; New York City and 39 states experienced minimal ILI activity, and the District of Columbia had insufficient data.

Re: Fluview 2011-2012 Flu Season: Weeks 40-9 (One Pediatric Death; Total Five)

Is it unusual that there were no additional antigenic characterizations for H3N2 during Week 9 from Week 8? Typo perhaps?

Week 8:

?Three hundred nineteen (78.4%) of the 407 viruses were characterized as A/Perth/16/2009-like, the influenza A (H3N2) component of the 2011-2012 influenza vaccine for the Northern Hemisphere.
?Eighty-eight viruses (21.6%) tested showed reduced titers with antiserum produced against A/Perth/16/2009.

Week 9:
