Objectives At the end of the session, members will have the capacity to: Identify three research facility techniques to test tolerant examples for flu. Portray contemplations in the utilization and understanding of fast tests for flu. Outline gets ready for lab based observation of flu in Wisconsin amid the 2009-10 season .

Slide 4

Brief Recap of Last Season Antigen Detection (Rapid) Testing Data Reported to WSLH, 2003/4 – 2008/9 Seasons Not an especially energizing year, until…

Slide 5

Brief Recap of Last Season The "season" turned out to be all the more energizing in May Novel H1N1 PCR testing was performed at WSLH, Milwaukee Health Department Laboratory, Midwest Respiratory Virus Program, Marshfield Clinic Research Foundation

Slide 6

Brief Recap of Last Season April 15, 2009 : CDC testing affirms 1 st human instances of novel H1N1 infection. April 17, 2009 : CDC testing affirms 2 nd human instance of novel H1N1 infection. April 23, 2009: 7 add up to cases - 5 instances of novel H1N1 affirmed in California; 2 cases in Texas. April 26, 2009: U.S. announces general wellbeing crisis . April 30, 2009: Per CDC - 91 add up to instances of novel H1N1 flu in: Arizona, California, Indiana, Kansas, Massachusetts, Michigan, Nevada, New York, Ohio, Texas. May 3, 2009: Per CDC – 226 aggregate cases in 30 states, including Wisconsin . June 11, 2009: W.H.O. raised the overall pandemic ready level to Phase 6. 

Brief Recap: novel H1N1 Influenza Detected all through the State In Wisconsin: Confirmed Cases: 4,583 Probable Cases: 1,814 Total Cases: 6,397 Source: http://pandemic.wisconsin.gov

Slide 8

Brief Recap: Influenza Detections Continued through the Summer

Slide 9

Expectations for 2009-2010 Season Probable (?) coursing infections Seasonal Influenza infections (in the immunizations) Influenza A (H1N1) - A/Brisbane/59/2007 (H1N1) Influenza A (H3N2) - A/Brisbane/10/2007 (H3N2) Influenza B - B/Brisbane/60/2008 (B/Victoria heredity) Novel H1N1 Influenza An infection Influenza A/California/07/2009 (H1N1) Concerns: Novel H1N1 Influenza An infection could transform into a frame that would bring about more serious disease. Antiviral defenselessness examples could change.

Slide 10

Expectations for 2009-2010 Season Purpose of expense absolved testing amid Spring 2009 reaction was case recognizable proof Purpose of charge excluded testing amid 2009-2010 season is reconnaissance . WSLH will cease expense for-administration testing

Slide 11

Laboratory-Based Influenza Surveillance in Wisconsin

Slide 12

Expectations for 2009-2010 Season Objectives of flu reconnaissance Determine when flu infections are coursing * Determine where flu infections are circling * Track geographic spread of flu Track flu related disease Measure the effect of flu on genuine sickness and mortality Detect changes in flu infections * Infection by novel infections * Optimize utilization of immunizations and antivirals * = reliant on research facility commitments

Slide 13

Components of Wisconsin's Laboratory-Based Influenza Surveillance Virology Laboratories (~11) PCR Laboratories (? number) Sentinel Submitters (~30) Rapid Test Sites (~145) WSLH Public Health Epidemiologists Laboratories Clinicians WSLH = Wisconsin State Laboratory of Hygiene

Slide 14

Laboratory-Based Influenza Surveillance During 2009-10 Season Sentinel Submitters: ~ 30 enlisted human services suppliers give predetermined number of examples to WSLH. Virology (culture) Laboratories: ~ 11 research facilities give week by week reports and chose viral detaches. PCR Laboratories: ? Research centers give week after week reports and chose positives.

Slide 15

Laboratory-Based Influenza Surveillance During 2009-10 Season Rapid Test (antigen recognition) Sites: Sites give week by week reports and chose tests to WSLH. 20 selected "Organized" accommodation destinations to send initial 5-10 every week ( paying little respect to quick test outcome ) These locales will be particularly enlisted and selected. Other quick test locales to send first positives, until told to stop. Notification will be given in Virus Surveillance Reports, WCLN Laboratory Messages and posted on the WSLH site. Demands for examples and notification to stop entries will be founded on local movement.

Slide 16

Laboratory-Based Influenza Surveillance During 2009-10 Season Fee-absolved testing criteria for novel flu A (H1N1): Pregnancy Child 2 years old or less Healthcare Worker Resident or Staff of Residential or Correctional Facility Hospitalization Death Public Health Department Approval

Slide 17

Laboratory-Based Influenza Surveillance During 2009-10 Season Note: " Positive fast flu A test outcome " is no longer included as a programmed foundation for fee–exempt testing, however … Fee-excluded corroborative testing of quick flu A test outcomes will be accessible (pretty much as in earlier years), yet will be suspended in every district in view of action.

Slide 18

Laboratory-Based Influenza Surveillance During 2009-10 Season Packet of data , including shapes & directions, will be given to viral culture, PCR, & fast test destinations (as in earlier years). Will likewise present parts on the WSLH site Web-based reporting is accessible for fast testing locales; directions will be in the parcel.

Slide 19

Laboratory-Based Influenza Surveillance During 2009-10 Season New structures will be given in bundles and presented on WSLH site. "Fillable" order shape for novel H1N1 reconnaissance will be posted on the WSLH site. It would be ideal if you finish submitter data before printing.

Slide 20

Laboratory-Based Influenza Surveillance During 2009-10 Season Updates and reports will be given by means of WCLN research facility message, WSLH Virus Surveillance Report, and site. State and territorial diagrams for Culture, PCR, & antigen identification will be presented on the WSLH site – tap on "Reconnaissance Reports" at http://www.slh.wisc.edu/labupdates/

Slide 21

Laboratory-Based Influenza Surveillance During 2009-10 Season Teleconferences and online classes will be held as required. Yearly flu redesign video chat will be given in October.
