West Nile cases primarily occur in midsummer or early fall.

This mosquito-borne disease was brought to the U.S. by travelers from the Caribbean. It’s now found in more than half of the US states, including Illinois. The disease is rarely fatal but causes symptoms such as severe headache, fever, vomiting, rash, and joint pain. Joint pain can linger for several months.

Zika Virus

The Zika Virus is a relatively new mosquito-borne disease. It has become a problem in South America, primarily Brazil. It raised concerns when persons suffering from the Zika virus developed Guillain-Barre syndrome, and affected pregnant women began giving birth to babies with severe birth defects. In response, the CDC has issued travel notices for people traveling to regions and certain countries where Zika virus transmission is ongoing.

2025 Tire Collection has wrapped up 

The Livingston County Health Department assists in the collection of unused tires in an effort to reduce mosquito breeding grounds by providing a means of environmentally safe tire disposal. Tires are notorious breeding grounds for mosquitoes. After sitting outdoors, tires often fill with stagnant water and nutritious leaves making them perfect environments for mosquitoes to thrive.

Tire disposal program eligibility requirements:

• Collection dates TBA.
• Appointment is required. No exceptions. Call the LCHD Environmental Health Division at 815-842-5921 to schedule.  
• No farm or construction equipment tires can be accepted.
• Tires can be off or on the rim.
• Tires must be unloaded by the individual dropping them off
• Collection will end once funding has been allocated for disposal costs.
