Illinois Reports Year’s First Case of West Nile, Officials Urge Precautions

Illinois health officials have confirmed the first human case of West Nile virus in 2023, marking an early start to the mosquito season.

The individual, who resides in southern Illinois, was hospitalized with complications related to the mosquito-borne illness.

This case is the earliest report of West Nile virus in the state since 2016, signaling a need for vigilance, especially as warm weather brings more mosquitoes.

What is West Nile Virus?

West Nile virus is transmitted by the bite of a Culex mosquito, which contracts the virus after feeding on infected birds.

Although most people infected with West Nile virus experience no symptoms, some may develop fever, nausea, headaches, and muscle aches that can last from several days to a few weeks.

In rare cases, the virus can lead to more severe illnesses, particularly in people with weakened immune systems and the elderly.

Early Warning for Mosquito Season

Dr. Sameer Vohra, Director of the Illinois Department of Public Health (IDPH), noted, “The fact that we are seeing the first human case of West Nile virus so early in the season serves as a timely reminder—especially for seniors and those with weakened immune systems—to protect yourself from illnesses caused by mosquito bites.”

Protect Yourself From Mosquitoes

With mosquito season starting earlier than usual, it’s crucial to take steps to reduce your risk of exposure:

REPEL: Wear long sleeves, pants, and use insect repellent with active ingredients like DEET, picaridin, or oil of lemon eucalyptus. Always follow the label instructions, and consult your doctor before using repellent on babies.
REMOVE: Eliminate standing water in your yard, such as in roadside ditches, flooded yards, or water containers, as these are prime breeding grounds for mosquitoes.
REPORT: Contact your local health department if you notice areas of standing water that haven’t drained within a week. They may be able to treat the area to help stop mosquito breeding.
