The Pennsylvania Department of Health has reported four confirmed and another possible six human cases of swine flu.

The new strand is known as H3H2v and health officials told 6 News everyone infected has ties to the Huntingdon County Fair, which just wrapped up last week.

"The only cases that we have identified statewide have been in a small group of youth participants where we've confirmed the illness in four members of that group," said Dr. Stephen Ostroff of the Pennsylvania Deptartment of Health. "Then in addition to that, we have six other individuals that have an illness that looks just like the ones that have confirmed illness."

That makes 10 cases all allegedly stemming from the Huntingdon County fair, but Kurt Eysenbach, the superintendent of livestock, said that people coming down with the flu after the fair ends isn't uncommon.

"Following the fair and the week since,a higher than usual number of exhibitors and people who were at the fair have come down with a flu-like illness," said Eysenbach.

And he said he's not even sure at this time that the outbreak is linked to livestock.

"Mainly I think it's where you get congregations of large numbers of people together, you increase the likelihood of transmitting any kind of disease," said Eysenbach.

But Ostroff said otherwise.

"It's only very rarely that we see a circumstance where there are strains that normally occur in pigs, then start causing disease in humans," said Ostroff. "This is one of those circumstances."

Ostroff said the best advice he can give to fair-goers is to refrain from eating or drinking around live animals and to wash your hands, something Eysenbach said they urge people to do every year.

"We post a lot  of signs urging people to wash their hands," said Eysenbach. "We also post, at the end of barns, hand-sanitizing solutions for people to use."

Both the state health and agriculture departments told 6 News this strain of flu cannot be transmitted from human to human. They also emphasized it is not possible to become infected by preparing or eating pork.

Officials said it's not normally a life-threatening illness, but it is dangerous to people who can't fight the virus because of medical reasons.

Anyone who thinks they may be infected should see a doctor.
