Welcome to North Shore Health Department North Shore Health Department Highlights 7/18/2017 Did You Know? The first dead bird testing positive for West Nile virus (WNV) has been reported in Milwaukee County. WNV is most commonly transmitted to humans by mosquitoes. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread the virus to humans and other animals. Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms, while less than 1% of infected people develop a serious, sometimes fatal, neurologic illness. While serious illness can occur in people of any age, those over 60 years of age are at the greatest risk for severe disease. People with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and people who have received organ transplants, are also at greater risk for serious illness. The health department recommends the following tips to prevent mosquito bites: Limit time spent outside at dawn and dusk, when mosquitoes are most active. Apply insect repellent 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. Missed the highlights? Click here to view previous highlights.
