Louisville, Ky. (WHAS11)- The Center for Disease Control says the swine flu could be making a comeback.
Since August, 12 people have come down with a specific sub-type of the disease.
It has showed up in five states, including Indiana.
If you remember the swine flu was a global problem in 2009.
Now there is some worry over a possible recurrence in the US.
They say this year's flu vaccine should protect you from the strain.
