influenza surveillance refresher
Influenza Surveillance Refresher
  • VDH Office of Epidemiology tracks the following key indicators to establish the statewide influenza activity level each week
    • Visits to emergency departments and urgent care centers for influenza-like illness (ILI)
      • ILI = fever with cough and/or sore throat
    • Laboratory test results confirming influenza
    • Outbreaks
2011 2012 influenza season
2011-2012 Influenza Season
  • Late, short, and mild
    • Virginia and U.S.
    • Compared to past 15 flu seasons
  • Late – reached widespread level (affecting majority of regions of the state) week of February 25, 2012
    • The latest time in the seasons studied
  • Short – stayed at widespread for only 3 weeks
    • Average of 9 weeks at widespread in 14 seasons (excluding May-December 2009 pandemic period)
  • Mild – highest percent of visits for ILI only 2%; only 4 confirmed outbreaks
    • Peak ILI 5% in 2010-2011; 33 outbreaks in 2011
vaccine composition for 2012 2013
Vaccine Composition for 2012-2013
  • Composition has been identical for past two seasons
  • WHO and FDA recommend changes for next season’s vaccine
    • A/California/7/2009-like (2009 H1N1) – same
    • A/Victoria/361/2011-like (H3N2) – change
    • B/Wisconsin/1/2010-like (B/Yamagata lineage) – change
  • Recommendation based on surveillance on circulating viruses, serological responses to 2011-2012 trivalent seasonal vaccines, and availability of candidate strains and reagents
who surveillance for influenza a h5n1 avian flu
WHO Surveillance for Influenza A/H5N1 (Avian flu)
  • 600 cases since 2003 (as of 4/5/2012)
  • 353 (58.8%) have died
  • 2012
    • 22 cases, 13 deaths
    • Bangladesh, Cambodia, China, Egypt, Indonesia,Viet Nam
  • Cases associated with exposure to sick or dead poultry or to live bird markets
  • Spread to household or community contacts not being seen
conclusion
Conclusion
  • Influenza continues to behave unpredictably
  • Relatively mild season in U.S. this year
  • Circulating viruses matched vaccine strains
  • WHO continues to actively monitor avian influenza
  • Surveillance, vaccine, and vigilance are necessary for influenza control
