  • Colorado 2015-16 Flu Season



    Synopsis: For the week ending October 31st, flu activity was minimal.

    * Since the official start of the 2015/16 season, two influenza-associated hospitalizations have been confirmed (both during the week ending 10/24). No influenza-associated hospitalizations were confirmed during the most recent week (10/31).
    * Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area increased slightly from 0.6% to 0.7%, but remained below seasonal baseline (1.0%). Influenza-like illness reported by Mesa County remained low at 0.5%.
    * Sentinel hospital labs (19/25 reporting) tested 407 specimens and 6 were positive for influenza (three each for influenza A and influenza B). Caution should be used when interpreting these data based on the possibility of false positive results with the current use of rapid flu tests
    * Since 10/4/2015, 15 specimens have been sent to the State lab for confirmation (seven from inpatient hospital visits and eight from outpatient hospital visits). Of which, two (13%) confirmed positive for influenza A (H3).
    * No outbreaks associated with influenza have been reported thus far.  No pediatric deaths associated with influenza have been reported thus far.

                          during the week ending April 9 and 47 from previous weeks. The total number of hospitalizations was
                          1337 from 49 counties. The number of hospitalizations due to influenza B appears to have peaked the
                          week ending March 26, 2016. (See Figures 1 and 2 and Tables 1 and 2.)
                           Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area fell to
                          1.3% (compared to 1.5% the previous week). Influenza-like illness reported by Mesa County decreased to
                          1.0% (compared to 1.3% the previous week). (See Figures 3 and 4.)
                           Since Oct. 4, 2015, 1557 specimens have been sent to the State lab for confirmation (420 from inpatient
                          hospital visits and 1137 from outpatient hospital visits). Of the 1331 PCR positive tests, 1194 (89.7%)
                          tested positive for influenza A and 137 (10.3%) tested positive for influenza B. Among influenza A
                          positive specimens, 229 (17.2%) were H3N2 and 963 (72.4%) were 2009 H1N1. (See Table 3.)
                           Sentinel hospital labs (21 of 25 reporting) tested 1292 specimens and 180 (13.9%) were positive for
                          influenza. (See Figure 5.)
                           21 outbreaks associated with influenza in a long-term care facility have been reported thus far.
                           The first pediatric death associated with influenza of the season was confirmed during the week ending
                          March 26.
                           Among recent seasons, this is the latest influenza peak week since 2011-2012. (See Figure 6.)

                            Influenza Season 2015 - 2016
                            Reporting through the week ending April 16, 2016


                            Synopsis
                            For the week ending April 16, flu activity decreased across the state. After accounting for reporting delays,
                            the number of hospitalizations due to influenza appears to have peaked the week ending March 12, 2016.
                             There were 85 additional influenza-associated hospitalizations reported; 43 with a collection date during
                            the week ending April 16 and 42 from previous weeks. The total number of hospitalizations was 1422
                            from 50 counties. It is unclear if the number of hospitalizations due to influenza B has peaked yet. (See
                            Figures 1 and 2 and Tables 1 and 2.)
                             Influenza-like illness reported by Kaiser Permanente for the Denver-Boulder metropolitan area fell to
                            1.0% (compared to 1.3% the previous week). Influenza-like illness reported by Mesa County decreased to
                            0.9% (compared to 1.0% the previous week). (See Figures 3 and 4.)
                             Since Oct. 4, 2015, 1598 specimens have been sent to the State lab for confirmation (457 from inpatient
                            hospital visits and 1141 from outpatient hospital visits). Of the 1366 PCR positive tests, 1213 (88.8%)
                            tested positive for influenza A and 153 (11.2%) tested positive for influenza B. Among influenza A
                            positive specimens, 243 (17.8%) were H3N2 and 968 (70.9%) were 2009 H1N1. (See Table 3.)
                             Sentinel hospital labs (23 of 25 reporting) tested 1236 specimens and 129 (10.4%) were positive for
                            influenza. (See Figure 5.)
                             25 outbreaks associated with influenza in a long-term care facility have been reported thus far.
                             The first pediatric death associated with influenza of the season was confirmed during the week ending
                            March 26.
                             Among recent seasons, this is the latest influenza peak week since 2011-2012.
