Flu season is coming early in parts of the United States: This time last year, flu cases were lower in the Chicago area than they are now, according to data on Google's Flu Trends. (Libertyville-specific data is not available on Flu Trends.)

In Chicago, and overall in Illinois, activity is now considered "high" on a scale of minimal, low, moderate, high and intense.

At this time in 2011, activity was considered "moderate," but reached "high" by early March, according to Flu Trends.

If you're considering getting a flu shot, here are some places in Libertyville that offer the vaccine (besides your own doctor, of course):

According to this week's CDC Flu activity report, influenza levels are on the increase across the country. 

Five states—Texas, Louisiana, Alabama, Mississippi, Tennessee—are reporting flu rates not normally seen until January, according to the Centers for Disease Control. The flu season normally peaks in January and February.

Holiday travel and more time spent indoors due to soggy weather will contribute to the spread of the flu virus, so now is the time to get vaccinated.

The Centers for Disease Control and Prevention offers the following information:

• Who should get vaccinated
• When to get vaccinated
• Selecting a flu vaccine
• Symptoms, complications and severity
• Treatment if you get the flu
• How flu spreads
