The presence of West Nile has been confirmed in about half of all Wisconsin counties, according to the health department.

Residents are urged to protect themselves from mosquito bites.

Last year, four cases were confirmed in Macomb County.

West Nile Virus is a disease transmitted to humans through infected mosquitoes. Repellents with picaridin, IR3535 and some oil of lemon eucalyptus and para-menthane-diol products also provide protection against mosquito bites.

Limit outdoor activities, wear trousers and long sleeves and use repellent during the hours from dusk to dawn.

Empty water from mosquito breeding sites around the home, such as buckets, unused kiddie pools, old tires or similar sites where mosquitoes lay eggs.

Maintain window and door screening to help keep mosquitoes outside. Mosquitoes become infected if they bite a bird infected with the virus. Many people infected with the virus will not have any symptoms or will experience a mild illness such as body aches, fever and headache. People over 50 and those with immune system deficiencies are at a higher risk for severe illness from the virus.
