West Nile Virus bird surveillance program starts

 
NEWMARKET York Region Health Services announces that the West Nile Virus bird surveillance program has begun.  Residents are asked to report dead crows and blue jays as a tool to determine possible West Nile Virus activity in York Region.
 
Like humans, West Nile Virus is transmitted to the bird population by infected mosquitoes. Crows, blue jays and other raptorial species are known to be most susceptible to the disease and act as early warning signs for the presence of the virus in a particular area.
 
There were 5 human West Nile Virus cases, 22 birds and 14 mosquito pools testing positive for the virus in York Region in 2005. The Ministry of Health and Long-Term Care attributed 8 deaths in the province last year to West Nile Virus illness.
 
Report dead crows and blue jays
York Region Health Services requests that residents report sightings of dead crows and blue jays. Suitable specimens may be collected and submitted to the Canadian Co-operative Wildlife Health Centre in Guelph for testing. All crows and blue jays that are reported will help to track the travel of the virus within York Region.
 
Dead crows and blue jays are to be reported to York Region Health Services through the Health Connection information line at 1-800-361-5653.
 
 Suitable specimens - A suitable specimen must be a crow or blue jay that has died less than 12 hours prior to collection. These birds may be collected by a contractor on behalf of York Region Health Services and sent for testing
 Unsuitable specimens Most dead birds will not be suitable for testing, but knowing what species they are and where they died is important information. Even if unsuitable for testing, residents are requested to call the Health Connection information line with details. Do not handle birds with bare hands or dispose of dead birds through the municipal garbage systems. If you choose to handle a dead bird, wear rubber gloves, double bag the bird and contact Health Connection to request pick-up.
 Dead bird pick-up service is available - Please contact Health Connection for pickup of dead birds of any species.
 
West Nile Virus is a vector-borne virus that can in rare cases cause serious illness. The risk of
becoming seriously ill as a result of infection with West Nile Virus is low and most people who become infected experience no symptoms or have very mild illness. The virus is named after the West Nile region of Uganda where it first appeared in 1937.
 
The chances of being bitten by an infected mosquito are rare. In fact, for the very few who are bitten by an infected mosquito most do not even know it, with approximately four out of five people infected by West Nile Virus not showing any symptoms or signs of illness at all.
 
The symptoms for West Nile Virus illness consist of fever, muscle weakness, stiff neck, confusion, severe headache, and a sudden sensitivity to light. For a very rare few, the virus causes serious neurological illness including encephalitis (inflammation of the brain).
 
See the attached Fact Sheet on York Region's 2006 West Nile Virus Control Plan and simple,
common sense precautions that should be taken.

York Region's 2006 West Nile Virus (WNV) Control Plan
 

NEWMARKET The York Region West Nile Virus (WNV) control plan for 2006 includes:
 Mosquito, bird and human surveillance
 WNV control activities, including a larviciding strategy:
- The first larvicide application will be in June and the subsequent applications will be in July, August and September. These applications will target all catch basins along regional and municipal roads and in catch basins, as required, on private property
- Methoprene is the larvicide that will be used. It comes in a slow-release pellet-like formulation and is administered in catch basins when the mosquito is in the larval stage of development. It interferes with the mosquito life cycle, preventing the mosquito larva from reaching maturity. It is not sprayed. It has been approved by both the provincial and federal governments and is considered low risk for humans, pets and the environment when it is applied according to label directions
 The WNV control plan also includes public education regarding common sense and effective measures to prevent exposure to WNV
 
Prevention and protection are the best ways to protect yourself and your family from WNV. There are simple and common sense precautions that should be taken:
 
 Minimize outdoor activities where and when mosquitoes are most active such as dusk, night and dawn
 Wear protective clothing such as long sleeved shirts, full-length trousers, socks, light coloured clothing and tuck pant legs into socks when possible
 Consider using an insect repellent, as directed
 Make sure screens on your home are tight-fitting and in good repair
 Mosquitoes breed in still water. Eliminate stagnant water around your property which may gather in pool covers, flower pots, children's pools, old tires and birdbaths
