Information on the West Nile Virus

It was reported in the D&C front page headlines on August 5, 2006 that the West Nile Virus was found for the first time this year in Monroe County in two different crows. According to the article, we are just the third county in upstate NY to identify the virus in crows this summer. However, this is not a panic situation as we have found it each year in Monroe County since 2000, with eight crows being found positive in 2005. The surprise is that the first occurrence was later than normal this year, and this could be a good sign that the disease is leveling off. The way people get West Nile virus is through a bite from an infected mosquito, and the crows are an indicator that the virus is around as they are especially susceptible to it. Keep in mind that only 1 in 5 people that are bitten by a infected mosquito ever show any symptoms and only 1 in 150 develop the brain swelling that makes the disease potentially life threatening. Age is a factor in vulnerability with those over 50 having a higher risk of the disease causing serious symptoms.

Information on how to avoid the virus:

The best way to reduce this risk is to avoid being bitten by mosquitoes. Stay away from wooded, marshy or high grassy areas at all times. And stay inside during the most active feeding periods. For the species we are most concerned about, this is from dusk to a few hours after dusk. Just prior to sunrise is another time period of concern. If someone chooses or has to be out in the above locations or during the most active feeding period, long pants, socks and long sleeve shirts are recommended. They may also want to use some form of repellent, but they should be careful with children. There are products available made specifically for children which generally have less active ingredient.  Another way to help themselves is to make sure there is no standing or stagnant water in their immediate area. This goes for things like tires or any other thing in their yard that would collect water.
