Ohio, which ranked second nationally last year for swine flu, made it through the fair season without any cases, state health officials said.
One Ohio man who did contract the virus had attended a fair in West Virginia, said Tessie Pollock, spokeswoman for the Ohio Department of Health.
In 2012, Ohio experienced its largest outbreak of the H3N2v (variant) with 107 cases and Butler County led the state with 17 cases. Most cases across the state were related to prolonged exposure to pigs at the fairs.
Fair officials said the extreme heat and dry conditions last year caused the pigs to stress out and more easily become sick.
The Ohio Department of Agriculture called for stricter handling of pigs to identify and isolate sick swine among other safeguards for the 2013 fair season.
