  • Fluview 2011-2012 Flu Season: Weeks 40-39 (No Pediatric Deaths; Total 34)

    During week 40 (October 2-8, 2011), influenza activity was low in the United States.

    Viral Surveillance: Of the 1,343 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, 16 (1.2%) were positive for influenza.
    Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below the epidemic threshold.
    Influenza-associated Pediatric Deaths: No influenza-associated pediatric deaths were reported
    Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 1.0%, which is below the national baseline of 2.4%. All 10 regions reported ILI below region-specific baseline levels. Forty-eight states and New York City experienced minimal ILI activity and the District of Columbia and two states had insufficient data.
    Geographic Spread of Influenza: The geographic spread of influenza in the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and 20 states was reported as sporadic; Guam and 29 states reported no influenza activity, and one state did not report.

    Re: Fluview 2011-2012 Flu Season: Weeks 40-38 (No Pediatric Deaths; Total 34)

    Week 38:
    No influenza-associated pediatric deaths; total 34

    ILI: 1%
    2.4% positive for influenza (61% B)
    P&I deaths: 6.2%

    From July 12 through September 27, 2012, a total of 306 infections with influenza A (H3N2) variant (H3N2v) viruses have been reported from ten states. One new case has been reported since last week’s update. Cumulative totals by state since July 12 are: Hawaii [1], Illinois [4], Indiana [138], Maryland [12], Michigan [6], Minnesota [4], Ohio [107], Pennsylvania [11], West Virginia [3], and Wisconsin [20]. Sixteen H3N2v-associated hospitalizations and one H3N2v-associated death have been reported. The vast majority of cases have occurred after prolonged swine exposure, though instances of likely human-to-human transmission have been identified. At this time no ongoing human-to-human transmission has been identified.

    As a result of enhanced surveillance activities for H3N2v, one infection with an influenza A (H1N1) variant (H1N1v) virus and three infections with influenza A (H1N2) variant (H1N2v) virus have been detected since July 2012, bringing the total number of variant influenza virus infections to 310.

    Week 36:
    No influenza-associated pediatric deaths; total 34

    ILI: 1.1%
    2% positive for influenza
    P&I deaths: 6%

    From July 12 through September 13, 2012, a total of 305 infections with influenza A (H3N2) variant (H3N2v) viruses have been reported from ten states. This is an increase of 9 over last week’s report. Cumulative totals by state since July 15 are: Hawaii [1], Illinois [4], Indiana [138], Maryland [12], Michigan [6], Minnesota [4], Ohio [106], Pennsylvania [11], West Virginia [3], and Wisconsin [20]. Sixteen H3N2v-associated hospitalizations and one H3N2v-associated death have been reported. The vast majority of cases have occurred after prolonged swine exposure, though instances of likely human-to-human transmission have been identified. At this time no ongoing human-to-human transmission has been identified.

    As a result of enhanced surveillance activities for H3N2v, one infection with an influenza A (H1N1) variant (H1N1v) virus has been detected in Missouri in a patient who became ill after contact with swine. The patient has recovered from their illness. Confirmatory testing at CDC identified H1N1v with the matrix (M) gene from the 2009 H1N1 influenza virus in specimens collected from this patient. Cases of H1N1v have been detected previously, and the current case marks the second report of H1N1v with the M gene from the 2009 H1N1 virus. This H1N1v case, in addition to the H3N2v cases outlined above and the H1N2v cases reported previously, brings the total number of variant influenza virus infections detected since July 2012 to 309.

    Novel Influenza A Virus:

    From July 12 through August 9, 2012, a total of 153 infections with influenza A (H3N2) variant (H3N2v) viruses have been reported in four states (Hawaii [1], Illinois [1], Indiana [120], and Ohio [31]). So far during the current outbreaks, two persons have been hospitalized as a result of their illness; no deaths have occurred. At this time no ongoing human-to-human transmission has been identified and all cases have reported contact with swine prior to illness onset. Public health and agriculture officials are investigating the extent of disease among humans and swine, and additional cases are likely to be identified as the investigation continues. Additional information on these cases can be found in the MMWR. Because of reporting deadlines, the state totals reported by CDC may not always be consistent with those reported by state health departments. If there is a discrepancy between these two counts, data from the state health departments should be used as the most accurate number.
    CDC is required to report all cases of human infection with novel (non-human) influenza viruses – including influenza viruses of swine origin – to the World Health Organization (WHO) as part of the International Health Regulations (IHR). Domestically, CDC reports these cases in this report and on its website. Early identification and investigation of human infections with novel influenza A viruses is critical in order to evaluate the extent of the outbreak and possible human-to-human transmission. Additional information on influenza in swine, variant influenza infection in humans, and strategies to interact safely with livestock can be found at http://www.cdc.gov/flu/swineflu/infl...uses-h3n2v.htm.

    Re: Fluview 2011-2012 Flu Season: Weeks 40-29 (One Pediatric Death; Total 34)

    Week 29:
    One influenza-associated pediatric death was reported to CDC during week 29 and was associated with an influenza B virus. The death reported during week 29 occurred during the week ending March 31, 2012 (week 13); total 34

    ILI: 0.9%
    4.4% positive for influenza: majority B
    P&I deaths: 5.6%

    Four human infections with novel influenza A viruses were detected in Indiana. The four persons were infected with an influenza A (H3N2) variant virus similar to those identified in the 13 human infections that occurred between July 2011 and April 2012 in Indiana (2), Pennsylvania (3), Maine (2), Iowa (3), Utah (1) and West Virginia (2). None of the four persons were hospitalized and all have recovered. All four persons reported close contact with swine prior to illness onset. Public health and agriculture officials are investigating case contacts and sources of exposure; no additional confirmed cases have been detected at this time.
