A cluster of flu cases linked to contact with pigs has doctors at the Centers for Disease Control and Prevention warning people to wash up and avoid eating around animals as they attend county and state fairs.
The new influenza strain sickened at least 12 people last week. All cases involved recent contact with pigs at agricultural fairs. Hawaii and Indiana each has one case, and 10 were linked to last week's Butler County Fair in Ohio. Four other cases have been linked to a county fair in Indiana that ran July 8-14. None resulted in hospitalization or death.
