FOND DU LAC COUNTY, Wis—A dead crow, found on July 25th in Fond du Lac County has tested positive for West Nile virus.
The Fond du Lac County Health Department says it is the first bird to test positive since the surveillance started in May.
In nature, mosquitoes become infected with West Nile virus by feeding on infected birds and can transmit the virus to other animals, birds, and humans.
The Department of Health Services has monitored the spread of West Nile virus since 2001 among wild birds, horses, mosquitoes, and people. During 2002, the state documented its first human infections and 52 cases were reported that year. During 2015, 9 cases of West Nile virus infection were reported among Wisconsin residents. West Nile virus infections in humans have been reported.
The Fond du Lac County Health Department recommends the following to help avoid the spread:
* Limit time spent outside at dawn and dusk, when mosquitoes are most active.
* Apply insect repellant to clothing as well as exposed skin since mosquitoes may bite through clothing.
* Make sure window and door screens are in good repair to prevent mosquito entry.
* Properly dispose of items that hold water, such as tin cans, plastic containers, ceramic pots, or discarded tires.
* Clean roof gutters and downspouts for proper drainage.
* Turn over wheelbarrows, wading pools, boats, and canoes when not in use.
* Change the water in birdbaths and pet dishes at least every three days.
* Clean and chlorinate swimming pools, outdoor saunas, and hot tubs; drain water from pool covers.
* Trim tall grass, weeds, and vines since mosquitoes use these areas to rest during hot daylight hours.
* Landscape to prevent water from pooling in low-lying areas.
