2. Humbert Zappia (ZAP) • New to public health • Training • Aquatic ecologist • Community ecology • Entomology • Contaminants • Animal health • Histopathology • Endocrine disruption • Toxicity HZ 5/14/04

3. Previous Employment • WVDNR • Creel survey • Population studies • WVU • Hormone mimic affect on non-target species • CONSULTING • Contaminant fate studies • USGS • Contaminants (toxicity, effects, fate) • Community ecology (landscape alteration effects-multi-variate studies) HZ 5/14/04

4. Hierarchy WVDHHR BPH OEHP DSDC IDEP • Zoonosis group HZ 5/14/04

5. Active Surveillance (The Cadillac) • All of the 55 counties within West Virginia • Multiple locations • Multiple times • Surveillance in all counties would • Aid in determining the spatial distribution of competent vectors • Enable application of resources to key areas • Aid in development of baseline data for planning and timing activities • Help produce efficient and appropriate reactions to future outbreaks HZ 5/14/04

6. Active Surveillance (The Reality) • Develop capabilities stepwise • Conduct surveillance as part of epidemiological response • Conduct surveillance in response to public • Increase number of individuals with surveillance expertise • Develop statewide database aggregated from county data • Conduct routine surveillance in counties where expertise exists (identification, and testing) HZ 5/14/04

7. Epidemiological Response • Conducted to • To determine vector or agent of disease (identification) • To determine potential source of vector or agent (actual habitat) • To recommend appropriate control for vector or agent to reduce current risk • Educate the public to reduce future risk HZ 5/14/04

8. Epidemiological Response (Continued) • Response triggered by • Positive human case of mosquito vectored disease • Animals testing positive (birds, mosquitoes, etc) HZ 5/14/04

9. Epidemiological Response (Continued) • Response includes • Interviewing and educating those affected • Identifying potential habitats within at least a 2 mile radius of where disease was suspected to have been vectored • Conduct larval sampling within larval habitats identified HZ 5/14/04

10. Epidemiological Response (Continued) • Response includes • Conduct adult sampling in area where disease suspected of being vectored • Identify species present (larval and adult) • Send adult mosquito pool/pools to OLS for abrboviral testing Aedes albopictus HZ 5/14/04

11. Epidemiological Response (Continued) • Response includes • Continue investigation as results of surveillance and tests indicate • Plan for and implement vector control strategies if needed • Continue education or intensify education efforts on a local basis of public on personal protection methods and habitat reduction HZ 5/14/04

12. Epidemiological Response (Continued) • Who will respond? • Counties or local departments with expertise • Public health entomologists • Additional counties trained by county or state personnel HZ 5/14/04

13. Response to public • Respond to reports of intense mosquito activity in areas • With dense population • Facilities that house those at increased risk (children, elderly, infirmed) • Conduct the same surveillance activities as conducted during the epidemiological response • Determine vector competency • Reduce or treat breeding sites • Educate public HZ 5/14/04

14. Expanding Surveillance Spatially and Temporally • Currently personnel from 5 counties trained in surveillance • Liz Green (Mid-Ohio Valley/Parkersburg) • Doris Irwin (Mercer) • Stan Mills (Cabell) • Rick Phillips (Parkersburg/Wood) • Anita Ray (Kanawha) • Patty Rodgers (Nicholas) HZ 5/14/04

15. Expanding Surveillance Spatially and Temporally (continued) • Utilize personnel from 5 counties to train others in surveillance techniques • These personnel can then conduct surveillance • Epidemiological • Response • Routine HZ 5/14/04

16. Expanding Surveillance Spatially and Temporally (continued) • Additional training • Train the 5 county personnel to identify adult mosquitoes • Currently class scheduled for June 8 and 9 • Others welcome • Train county personnel to identify larval mosquitoes HZ 5/14/04

17. Developing Statewide Database • County personnel and state health entomologists will identify mosquitoes from collections • Initially those from 5 counties • Then those from additional counties • Voucher specimens to be maintained and sent to public health entomologists for confirmation HZ 5/14/04

18. Developing Statewide Database (continued) • Geographic data, habitat data and photos to be recorded at time of collections • Accurately give location of vector population or positive pool (GPS) • Create historic record • Quantify all collections where possible for future statistical comparisons HZ 5/14/04

19. Developing Statewide Database (continued) • All surveillance data then aggregated at State level • Potential for remotely entering the data, getting sample #’s etc. HZ 5/14/04

20. Questions • What can we do to support your work? • General comments? • Vector control programs (are you aware of any within your county our area)? HZ 5/14/04
