    Re: Texas 2013-14 Flu Season Wk 45-04: 0 New Pediatric Deaths, 9 Total

    Wk 03, ending Jan 18

    Influenza-Associated Pediatric Mortality
    Three influenza-associated pediatric deaths occurred during week 3. The first death occurred in a 12-year-old resident of HSR 6/5S who had underlying health conditions. A specimen collected from the child was positive via PCR test for 2009 influenza A (H1N1). The child had multiple bacterial co-infections. The child was vaccinated for the current influenza season.

    The second death occurred in a 16-year-old resident of HSR 6/5S. A specimen collected from the child was positive via PCR test for influenza A (not subtyped). The child had an underlying medical condition and a blood culture positive for Pseudomonas aeruginosa. The child was not vaccinated for influenza for the current season.

    The third death occurred in a 3-month-old resident of HSR 8 with no underlying medical conditions. A specimen collected from the child was positive via rapid influenza test for influenza B. The child also had a cerebrospinal fluid culture positive for Streptococcus pneumoniae. The child was too young to be vaccinated for influenza during the current season.

    Nine influenza-associated pediatric deaths have been reported in Texas during the 2013-2014 influenza season. Cases of influenza-associated pediatric mortality (children <18 years of age) are reportable year-round and by law in Texas.

    Wk 04, ending Jan 25

    No new pediatric deaths were reported in wk 04.

    Influenza laboratory data and influenza-like illness (ILI) indicators have demonstrated a consistent decrease for the last four weeks; however, ILI intensity is still high throughout Texas.

    Antigenic Characterization
    * Influenza A (H1N1) [52]
    Fifty-two viruses were related to A/California/07/2009. This virus strain was included in the 2013-2014 influenza vaccine for the Northern Hemisphere

    * Influenza A (H3N2) [3]
    Three viruses were related to A/Texas/50/2012, an A (H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011. This virus strain was included in the 2013-2014 influenza vaccine for the Northern Hemisphere.

      1 new pediatric death was reported by the CDC in week 8. However, this one was apparently from an earlier week, as reported by Texas.

        Wk 13, ending Mar 29

        One influenza-associated pediatric death was reported in week 13.

        An influenza-associated pediatric death of a 10-year-old resident of HSR 2/3 occurred during week 13. The child had underlying medical conditions. A specimen collected from the child was positive for influenza B by PCR test. The child had received an influenza vaccination during the current season.

        Seventeeninfluenza-associated pediatric deaths have been reported in Texas during the 2013-2014 influenza season.

        Antiviral Resistance
        Three 2009 influenza A (H1N1) viruses from 354 samples have tested positive for the mutation that confers resistance to oseltamivir.

        Week 13 Positive specimens by type/subtype [n (%)]
        Influenza A: 29 (12.9%)

        Subtyping performed:6 (20.7%)
        * A (H1N1): 3 (50.0%)
        * A (H3N2): 3 (50.0%)
        Subtyping not performed : 23 (79.3%)
        Influenza B: 196 (87.1%)

          Wk 14, ending Apr 5

          Influenza-Associated Pediatric Mortality
          One influenza-associated pediatric death was confirmed in week 14.
          An influenza-associated pediatric death of a 17-year-old resident of HSR 2/3 with an underlying medical condition occurred during week 52 of 2013 (week ending December 28, 2013). A tissue specimen collected from the child was positive for influenza A (not subtyped) by PCR test and was also positive for Streptococcus by immunohistochemistry. The child was not vaccinated for influenza for the current season.

          Positive specimens by type/subtype [n (%)]
          Influenza A: 9 (5.9%)
          Subtyping performed: 1 (11.1%)
          A (H1N1): 0 (0.0%)
          A (H3N2): 1 (100.0%)
          Subtyping not performed: 8 (88.9%)

          Influenza B:144 (94.1%)

            Wk 29, ending July 19

            According to Texas influenza laboratory data and influenza-like illness (ILI) indicators there is low influenza activity occurring around the state. In addition, ILI activity increased ever so slightly compared to last week, but remains below the 2013-2014 state ILINet baseline of 4.35&#37;.

            Antigenic Characterization
            Since September 29, 2013, CDC has reported antigenic characterization results from 85 influenza A (H1N1) viruses, 25 influenza A (H3N2) viruses, and 48 influenza B viruses received from the Texas Department of State Health Services (DSHS) Laboratory. The DSHS Laboratory sends a representative sample of influenza viruses to the CDC throughout the flu season.

            Influenza A (H1N1) [85]
            Eighty-five (100%) viruses were related to A/California/07/2009. This virus strain was included in the 2013-2014 influenza vaccine for the Northern Hemisphere

            Influenza A (H3N2) [25]
            Twenty-five (100%) viruses were related to A/Texas/50/2012, an A (H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011. This virus strain was included in the 2013-2014 influenza vaccine for the Northern Hemisphere.
            Influenza B [48] Yamagata lineage [16]: sixteen (33%) influenza B/Yamagata-lineage viruses have been characterized from Texas. B/ Massachusetts/2/2012-like is included as an influenza B component of the 2013-2014 Northern Hemisphere trivalent and quadrivalent influenza vaccines.
            Victoria lineage [32]: Thirty-two (67%) influenza B/Victoria-lineage viruses have been characterized from Texas B/Brisbane/60/2008-like, which is included as an influenza B component of the 2013-2014 Northern Hemisphere quadrivalent influenza vaccine.

            Antiviral Resistance
            H1N1: 354 tested, 3 resistant
            No resistance was found in H3N2 or Flu B tested

            Influenza-Associated Pediatric Mortality
            NOTE: Texas reports its last pediatric death in June but the total number agrees with the CDC total.

            No influenza-associated pediatric deaths were reported during week 29.

            Nineteen influenza-associated pediatric deaths have been reported in Texas during the 2013-2014 influenza season. Cases of influenza-associated pediatric mortality (children <18 years of age) are reportable year-round and by law in Texas.
