An adult woman has been hospitalized with the disease, according to the Skokie Health Department.
It is the third confirmed case of West Nile in Cook County this year. The first two cases were women in their 60s from Des Plaines and Rolling Meadows.
West Nile was first detected in mosquitoes in Skokie in June 2012.
The Skokie Health Department said the hot summer weather is an ideal environment for mosquito breeding. The department urges residents to protect themselves and their families by taking these precautions:
Symptoms of West Nile infection are typically felt three to 15 days after being bitten by an infected mosquito.
Most infected people have mild symptoms such as a fever, headache and rash that last a few days.
In rare cases, West Nile 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 complications from the virus.
There is no specific treatment for West Nile other than to treat the symptoms. Contact your healthcare provider if you exhibit symptoms.
The Village of Skokie Health Department and the North Shore Mosquito Abatement District will continue cooperative surveillance and control efforts through the end of the mosquito season.
