## Breakout Summary:

**Breakout Summary:**
**Vector Management Programs**
**and**
**West Nile Virus Responses**

**Purpose - Review operational aspects of WN surveillance - response programs**
**Initiating and maintaining an integrated vector control program - J. Miller**
**Trigger events for mosquito adulticide applications in 2001 - B. Matyas**
**Planning for the arrival of WN virus.  V. Kramer**

## Degradation of NYC’s program since 1970
Development of program since 1999
Budget Sources
Personnel
Contractual services
Communication activities

**Initiating and maintaining an integrated vector control program - J. Miller**

## Regulatory environment
Pesticide controversy
Integrate DEP into activities
Environmental Impact Statement - Worth the cost
Recommendation
Invest in efforts to gain public confidence
Pesticide health effects

**Initiating and maintaining an integrated vector control program - J. Miller**

## Adulticide decision local unless public health emergency
Controversy - Adulticide use, not other activities
First year of WNV response
Aggressive (adulticide 2 mi. radius around event)

**Controversy - Adulticide use, not other activities**
**First year of WNV response**
**Aggressive (adulticide 2 mi. radius around event)**

**Trigger events for mosquito adulticide applications in 2001 - B. Matyas**

## Second WNV year response
More conservative, require more evidence to support adulticide decision
Based on EEE plan and 2001 WNV guidelines
Risk categories - defined indicators
Flexible - allow local interpretation
Triggers in plan not met in towns with horse/human cases
Recommendation
Refine surveillance indicators as new information accumulated
Expand surveillance/response into Fall, beyond traditional adulticide windows.

## California system - 30 years of accumulated surveillance data.
Existing components enhanced to deal with WNV
Sentinel chickens 
Mosquito surveillance
Human case surveillance
Veterinary (horse) surveillance
Dead bird surveillance added
WNV preparedeness workshop - for health agencies
Anticipate effect of WNV on system
Enhance lab capacity
Algorithm for bird testing
Refine public outreach to facilitate bird reporting/collecting

## California Encephalitis Program
Human encephalitis of unknown etiology
Extra testing for WNV
Quantified arbovirus risk model developed, being evaluated
WEE, SLE

## Involve / inform primary civic leaders
Involve / inform public
Refine surveillance tools - accumulated experience
Improve lab turnaround time 
Required for adequate response
Have a plan, develop flexible adulticide triggers
Anticipate effect of WNV on entire system
Maintain appropriate levels of interest in WNV and related health effects
What can health agencies do to maintain support for surveillance?

**Discussion / Recommendations**

## Personal Protection message
How do we communicate?
How do we know if it is working?
Rely on advice from professionals
Public health, mosquito control
Politically unfavorable recommendations
Control efforts must include efficacy monitoring
Do control efforts, particularly adulticiding, perform adequately?
Burden of accountability on control programs to document effectiveness
Basic research needed
Transmission ecology - vector biology
Predictive models
Intervention effectiveness
