PORTAGE COUNTY — West Nile virus has been detected in the area, according to a Portage County Health & Human Services (PCHHS) release.

The Division of Public Health reports that a dead crow found in Portage County on August 7, 2018 has tested positive for the virus. This is the first crow that tested positive for West Nile virus in Portage County since surveillance for the mosquito-transmitted virus began May 1.

“The positive bird means that residents of Portage County need to be more vigilant in their personal protective measures to prevent mosquito bites,” said Gary Garske, health officer.

West Nile virus is spread to humans through the bite of an infected mosquito. Mosquitoes acquire the virus by feeding on infected birds.

“Portage County residents should be aware of West Nile virus and take some simple steps to protect themselves against mosquito bites,” said Garske. “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 Division of Public Health at Portage County Health and Human Services recommend the following:
-Limit time spent outside at dawn and dusk, when mosquitoes are most active.
-Apply an insect repellant 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 mosquitoes from breeding by removing stagnant water from items around your
property, such as tin cans, plastic containers, flower pots, discarded tires, roof gutters,
and downspouts.
-Turn over wheelbarrows, wading pools, boats, and canoes when not in use.
-Change the water in bird baths and pet dishes at least every three days.
-Clean and chlorinate swimming pools, outdoor saunas, and hot tubs; drain water from
pool covers.
-Landscape to prevent water from pooling in low-lying areas, and trim tall grass, weeds,
and vines since mosquitoes use these areas to rest during hot daylight hours.

According to the PCHHS, The majority of people (80 percent) who are infected with West Nile virus do not get sick. Those who do become ill usually experience mild symptoms such as fever, headache, muscle ache, rash, and fatigue. Less than 1 percent of people infected with the virus get seriously ill with symptoms that include high fever, muscle weakness, stiff neck, disorientation, mental confusion, tremors, confusion, paralysis, and coma.

Older adults and those with compromised immune systems are at greater risk of developing central nervous system illness that can be fatal.

The Wisconsin Department of Health Services (DHS) 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 2017, 51 cases of West Nile virus infection were reported among Wisconsin residents. West Nile virus infections in humans have been reported from June through October; however, most reported becoming ill with West Nile virus in August and September.

DHS will continue surveillance for West Nile virus until the end of the mosquito season. To report a sick
or dead crow, blue jay, or raven, please call the Dead Bird Reporting Hotline at 1-800-433-1610.
