New swine flu strain prompts fairground health warning

Health officials are warning the public to keep a distance from pigs,after reports that more than 200 people in the U.S.contracteda relatively new strain of swine flufollowing contact withpigs at fairgrounds and petting zoos.

"Many Canadian families visit agricultural fairs taking place at this time of year and may be exposed to this flu virus," according to a public health notice issued by Health Canada earlier this week.

"The H3N2v virus doesn't spread easily from swine to peopleand even less easily from person to person. In most cases, the virus causes only mild illness in people," said the notice.

Still,Health Canadarecommends that pregnant women, children under five, and anyone at risk of serious complications from the flu avoid pigs altogether.

Not yet detected in Canada

TheH3N2 strainwas first detected in humans last year, according to Dr. Danuta Skowronski of the B.C. Centre for Disease Control.

"Even though we haven't seen this H3N2 virus in Canada we haven't detected it yet it's likely just a matter of time," she said.

The centreis tracking the virus to see if it has the potential to become the next pandemic, but Skowronski says a previous swine flu outbreak has provided some immunity for most people.

In 2009 the H1N1 virus also originated from swine, and was so novel that most people had no built-in immunity like they do now.

"The population is not completely naive, they've seen this before. There is some protection that will dampen the chances of spread of this virus and will diminish the chance of a pandemic," Skowronski said.

No contact at PNE pig races

In Vancouver the Pacific National Exhibition does allow children to get close to other animals, like newly hatched chicks, but apetting zoo at the fair was ended following an E.coli outbreak in 2009.

This year the fairis featuring pig races, but the public is being kept at a distance, according to spokeswoman Laura Ballance

"There's no direct guest-to-pig contact as part of that show... So we feel confident that is a show that is going to provide very, very low risk to the general public," said Ballance.
