WNV was found in one mosquito found in one testing trap in this area and also in one in Crystal Lake. That's one mosquito that was caught in a trap and tested. Obviously, if there is one, there is probably more than one.
The description of WNV that follows was included in that email and purportedly came from the Mayo Clinic. That source has not been confirmed.
"West Nile virus is an infection transmitted by mosquitoes. If you become infected with West Nile virus, you may not experience any signs or symptoms or you may experience only minor ones, such as fever and mild headache. However, some people who become infected with West Nile virus develop a life-threatening illness that includes inflammation of the brain.
"Mild signs and symptoms of a West Nile virus infection generally go away on their own. But severe signs and symptoms - such as a severe headache, disorientation or sudden weakness - require immediate attention.
The email continued, "Please make sure you take the proper precautionary mesures (sic) to protect yourself and your family, this includes your players as well as the family and friends we have out to enjoy our games and practices. (recommended by Mayo Clinic) Apply mosquito repellent with DEET to your skin and clothing. Choose the concentration based on the hours of protection you need - the higher the percentage (concentration) of the active ingredient, the longer the repellent will work. Avoid using DEET on the hands of young children, in case they put their hands in their mouths, or on infants under 2 months of age. When outside, cover your infant's stroller or playpen with mosquito netting."
