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

Eight states – Alabama, Alaska, Mississippi, New York, North Carolina, Ohio, Rhode Island and South Carolina – 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.

• Who should get vaccinated
