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.

Questions

• What can we do to support your work?
• General comments?
• Vector control programs (are you aware of any
  within your county our area)?
