The Door County Public Health Department was notified that a dead crow found in Door County on July 19 tested positive for West Nile virus. This is the first bird this year that tested positive for West Nile virus in Door County since surveillance for the mosquito-transmitted virus began May 1. Door County also had a dead crow test positive for West Nile virus in July 2017. Since one bird has tested positive for 2018, no more testing will be done with Door County birds this season. The positive bird means that residents of Door County need to be more vigilant in their personal protective measures to prevent mosquito bites. West Nile virus is spread to humans through the bite of an infected mosquito. Mosquitoes acquire the virus by feeding on infected birds. Door County residents should be aware of West Nile virus and take some simple steps to protect themselves against mosquito bites. West Nile virus is here to stay, so the best way to avoid the disease is to reduce exposure to and eliminate breeding grounds for mosquitoes.
The Door County Public Health Department recommends applying an insect repellent with DEET, IR3535, picaridin or oil of lemon eucalyptus to exposed skin and clothing; Make sure window and door screens are in good repair to prevent mosquito entry; Prevent breeding by removing stagnant water from items around your property.
