ST. PAUL, Minn. (KTTC) -- If you're planning to visit a county or the state fair soon, you might not want to pet the pigs especially if they look sick.
There's a new strain of H3N2 flu and the Centers for Disease Control and Prevention has reported a five-fold increase in the number of cases.
The CDC has been tracking H3N2 since 2011. The strain is spread from pigs to people. Pigs can spread their sickness just like people through coughing, sneezing, and runny noses.
The H3N2 case count jumped from 29 a week ago to 158 this week after more cases were reported in Indiana and Ohio.
Health officials say all the people who got sick were exposed to pigs either on a farm, visiting a swine barn, or attending a state or county fair.
So far, there have not been any confirmed cases in Minnesota.
