While many Wisconsin residents are more than ready to take advantage of the warmer weather and enjoy all the resources the state has to offer, the Department of Health Services (DHS) strongly encourages everyone to take care to avoid tick and mosquito bites. Both ticks and mosquitoes can transmit various illnesses. Lyme disease, which is spread by ticks, and West Nile virus, which is transmitted by mosquitoes, account for most of the disease spread by ticks and mosquitoes in Wisconsin. A recent report from the Centers for Disease Control and Prevention (CDC) shows Wisconsin among the top 20% of states reporting cases of tick-borne disease in the country.
