First Human Cases of West Nile Virus for 2017 Reported in Wisconsin 

Protect yourself against mosquito bites

State and local health officials are advising residents to continue to protect themselves against mosquito bites as they announce this year’s first confirmed human cases of West Nile virus (WNV) in residents of Oconto and Fond du Lac Counties.

The majority of WNV human cases in the state occur during the months of August and September. However, the risk of contracting WNV and other mosquito-borne illnesses is present anytime mosquitoes are active, so it is important for people to be vigilant in their personal protective measures to prevent mosquito bites throughout the summer and early fall.

The chances of a person contracting WNV are very low and most people infected with West Nile virus will not have any symptoms. Those who do become ill may develop a fever, headache, and rash that lasts a few days. Symptoms may begin between three to 15 days after being bitten by an infected mosquito. In rare cases, WNV can cause severe disease with symptoms such as muscle weakness, stiff neck, disorientation, tremors, convulsions, paralysis and coma. Older adults and people with compromised immune systems are at an increased risk of severe disease from the virus.

There is no specific treatment for West Nile virus other than to treat symptoms. If you think you have West Nile virus infection, contact your healthcare provider.

WNV is spread to people through the bite of an infected mosquito and is not transmitted person to person. Although few mosquitoes actually carry the virus, the Wisconsin Department of Health Services (DHS) and your local health department recommend that you follow these tips to minimize your exposure and eliminate breeding grounds for mosquitoes:

  • Limit time spent outside at dawn and dusk, when mosquitoes are most active.
  • Apply an EPA-registered insect repellant to exposed skin and clothing 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.

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 2016, 13 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. Please contact your local health department to report information regarding the above.

Lead Information:




Your health and your family’s health can be hurt by lead.



Everyone can be affected by lead, but pregnant women and children under the age of 6 are most at risk.

The main health concerns from lead exposure are damage to the nervous system and brain. The kidneys, red blood cells, and reproductive system can also be affected at higher exposures to lead.

If you are worried that you or your family has been exposed to lead, talk to your doctor about getting a blood lead test.


Lead can come from a number of sources in the home.



Most lead comes from old paint, as well as other things like toys, food, and soil. Information about these sources can be found at:

Water can also be a potential source of lead.  The City of Watertown Water Department follows and meets all requirements of the EPA & DNR pertaining to testing for lead in the water, please see link below for information regarding the City’s water quality.

You can test your water for lead. Contact a certified water testing laboratory to find out how to do this.


Individuals can reduce their exposure to lead in many ways.



You can reduce your exposure to lead in water by taking these steps:

  • Flush your pipes before using water.
  • Never use water from the hot-water tap for cooking or drinking.
  • Install a reverse osmosis water purification system designed to remove lead.

It is important to take steps to fix other lead sources in your home. For more information see:
