BOISE - Health officials say parents did it with the Chickenpox - intentionally putting a child around another who had the virus. Now, they worry some might think about throwing "Swine Flu Parties" to do the same.

The cartoon show South Park devoted a whole episode to it: "Pox Parties."

"We should intentionally have our boys play with a child who has the chicken pox," said one of the mother's one the show.

People have even posted videos on YouTube inviting other children to join their child's "Pox Party." In fact, one Boise mom remembers hearing parents exposing their child to the virus while her daughter was young.

"They thought that the sooner they got it, got it over with, the better," said Claudia, a Boise resident.

Now, it's the Swine Flu.

Boise State Football Coach Chris Peterson even made a comment about it during a press conference over the weekend.

"I think we ought to get all the sick guys and the whole team in one room and just get it over with because it seems like it's going through the whole team," he said.

In the past health officials say the intent of flu parties is for a person to become infected with a mild case of the disease so that if a more severe strain comes around later they have some natural immunity built up.

But the Centers for Disease Control and Prevention warn when it comes to H1N1 parents should not plan any kind of party.

"The most severe illnesses we are seeing are in children. It's unlike a seasonal flu in which the more severe illnesses are in older people," said Tom Shanahan, spokesman for the Idaho Department of Health and Welfare.

On Tuesday the CDC reported 44-percent of Swine Flu hospitalizations are in children 18-years-and-younger.

"You can't predict what effect it is going to have on your child," said Shanahan.

Party invite or not Boise mom Claudia says this is one party parents should skip when it comes to the RSVP.

"I think it is crazy," she said.

One of the biggest differences between a "Pox Party" and a "Swine Flu Party" is in most cases once a child is exposed to chickenpox they don't get it again. However, with the flu, new strains can develop each year meaning your child could get sick all over again.
