She was not hospitalized but was treated with antiviral medication.

Health department staff learned through its investigation that prior to becoming ill, she had a history of travel to the Chicago area, where the majority of Illinois' 1,200 cases are concentrated.

Cathy Coverston Anderson, from the health department, reminded residents that they should not become complacent about H1N1.

"Although we have only had two cases in McLean County and both have been relatively mild, everyone should remain aware and continue to wash their hands, practice cough etiquette and stay home when sick," Coverston Anderson said. "It is likely we will see additional cases here, but the department is ready to respond and minimize the impact of additional cases."

Symptoms of H1N1 flu are similar to regular human flu and include: fever, cough, sore throat, body aches, headache, chills and fatigue. The health department encourages anyone experiencing symptoms to stay home, but contact their health care provider to see if they should come in for testing or treatment.
