  4. 2012 Human case counts in Tarrant County* • Total cases: 279 • WNF -178 • WNND - 101 • Deaths - 11 • Incidence rate per 100,000: 14.5 • Cities with cases - 24 *For 2012 Arboviral season; Based on data reported as of 5:00 PM 02/22/2013

  7. Tarrant County Response • Mosquito surveillance • Resurgence of interest in participation • TCPH LRN operated to capacity • Adulticide application • Varied among municipalities • No generalized aerial spraying • Targeted ground spraying effective • IR was average among the metroplex counties…not the highest or the lowest • Risk communication

  8. Lessons learned • Limitations of using human case data to drive control efforts • Limitations of mosquito surveillance data • program implementation • No standard/structured trapping • No historical trap data • Effective communication is critical • Stakeholders • Media • Public • Local/regional partners

  9. West Nile Neuroinvasive Disease CSTE Epidemiologic Case Definition Must meet Laboratory Criteria AND Clinical Criteria Clinical Criteria: Fever, (>100.4 or 38C) as reported by pt or HCP, AND Meningitis, encephalitis, acute flaccid paralysis, or other acute signs of central or peripheral neurologic dysfunction, as documented by a physician, AND Absence of a more likely clinical explanation

  10. Recommendations for future response • Review/revise • response plans to increase mosquito pool surveillance • operational plans to reflect surveillance data (mosquito data to drive response) • communication plans • Communications with those in the position to make decisions
