  2. LEARNING OBJECTIVES • To identify the cause of West Nile Virus (WNV) • To identify symptoms associated with WNV • To explain current and ongoing action in the state of Illinois • To create awareness of the reality of the WNV threat and adherence to prevention measures.

  3. WHAT IS WEST NILE VIRUS? • A mosquito-borne virus (WebMD, 2009) • WNV can cause inflammation of the brain, spinal cord and surrounding tissues WebMD. (2009). West Nile Virus. Retrieved from http://www.webmd.com/a-z-guides/west-nile-virus-treatment-overview United States Geological Survey (USGS, 2002). Wild Birds Help Scientists Understand West Nile Virus. Retrieved from http://www. nwhc.usgs.gov/publications/fact_sheets/pdfs/fact_westnile_res.pdf

  4. HOW DOES WEST NILE VIRUS INFECT PEOPLE? • Through infected mosquito bite (CDC, 2006) • Mosquitoes get infected after feeding on infected birds (Chicago Tribune, 2009) • The mosquitoes that carry the infection spread WNV to human beings and to other animals when they are bitten (CDC, 2009) Chicago Tribune.

  5. SYMPTOMS ASSOCIATED WITH WNV • Serious symptoms are associated with WNV (CDC, 2006) • Milder symptoms are seen in some infected persons (CDC, 2006) • Some infected individuals show no noticeable symptoms (UPI.com, 2009) UPI.com (2009).

Retrieved from http://www.upi.com/Science_News/2009/10/13/Cells-predict-West-Nile-virus-infection/UPI-42941255450721/ Center for Disease Control. (CDC, 2006). West Nile Virus. Retrieved from http://www.cdc.gov/ncidod/dvbid/westnile/wnv_ factsheet.htm

  6. WNV AWARENESS IN ILLINOIS • West Nile Virus has a “seasonal epidemic pattern” in North America (CDC, 2006). • About 2,000 cases of WNV and deaths have been identified in Illinois since September, 2001 (IDPH, 2009). Center for Disease Control. (CDC, 2006). West Nile Virus. Retrieved from http://www.cdc.gov/ncidod/dvbid/westnile/wnv_factsheet.htm Illinois Department of Public Health. (IDPH, 2009).

  7. HISTORY OF WNVIN ILLINOIS • In 2001, laboratory analysis confirmed WNV in two dead crows found in Chicago southwestern suburb of Oat Lawn (Watson, 2004, IDPH, 2009; & Devitt, 2009) • In 2002, Illinois recorded, positive birds, mosquitoes, horses and first human cases and deaths from WNV IDPH, 2009) • In late 2002, Illinois reported more than 884 human cases, and 67 deaths (IDPH, 2009) Dewitt, T.(2009). University of Wisconsin News. Do Chicago’s Suburbs hold the key to understanding West Nile Virus? Retrieved from http://www.news.wisc.edu/16916 Watson, J. T; Jones, R. C; Gibbs, K; & Paul, W.

  8. HISTORY OF WNV INILLINOIS • In 2003, the attention-created by West Nile disease shifted westward. • Colorado recorded the highest infected cases of 2,947, passing the caseload number set the previous year by Illinois. • In 2004, Illinois infection rate went up a little • In 2005 and 2006, IDPH number of reported cases was at 252.

  9. CURRENT STATUS OF WNV IN ILLINOIS • Only 5 reported human cases this year in Cook, St. Clair, Tazewell and Williamson counties • Most affected are the middle aged and elderly • 1.5 times as many males as females are diagnosed with WNV Illinois Department of Public Health. (IDPH, 2009). West Nile Virus- 2009. Human Case Data. Retrieved from http://www.idph.state.il.us/envhealth/wnvsurveillance_humancases _09.htm

  10. NEXT LINE OF ACTION • More aggressive WNV surveillance is needed by IDPH for proper control and eradication measures • Recruit more personnel Illinois Department of Public Health. (IDPH, 2009). West Nile Virus. Retrieved from http://www.idph.state.il.us/envhealth/wnv.htm=surv

  11. AWARENESS INSCHOOLS AND NEIGHBORHOODS • Inform youth of protection measures • Reduce mosquito dwelling places • IDPH campaigns involving posters, bill boards and the use electronic media Illinois Department of Public Health. (IDPH, 2009). West Nile Virus. Retrieved from http://www.idph.state.il.us/envhealth/wnv.htm=surv

  12. PARTNER WITH HEALTH CARE • WNV information sharing between IDPH and health care facilities in the state • Monitoring of the elderly in nursing homes and other medical facilities • Posting of WNV recent updates on strategic places in hospitals, clinics and other health care agencies

  13. MORE PUBLIC AWARENESS Need for IDPH and other stakeholders in the state of Illinois to step up public awareness. IDPH partnership with CDC for efficient education tools and programs for health professionals. Mobile health clinics in the affected areas of the state Illinois Department of Public Health.
