According to Google's flu trends page, most of the country is under moderate status when it comes to the number of flu cases. They extrapolate this data based on search terms used by region/state. It's actually a good indicator, they say, since not everyone goes to the doctor for flu (or if they aren't sure if they have the flu, they're looking up information about symptoms, medications, etc. to combat the flu). The line is trending upward, with what looks like an expected peak in cases in February.
If you haven't gotten a flu shot yet, bear in mind that Lysol is offering a $5 rebate on your flu shot with purchase of one (1) Lysol product. The rebate runs through the end of February, leaving you plenty of time to get vaccinated if you haven't yet.
