Safety -- or Swine Flu Follies?

May 4, 2009— -- One woman's sniffle diverted an international flight Friday, several students' travel plans cost them their graduation ceremony Saturday and thousands of students in Dallas have had to put off their proms because of the threat of the swine flu virus.

But when Paula Martin heard last week that her two boys were sent home from school because they recently returned from a vacation in Mexico, the Boulder, Colo., mom put her foot down.

"My kids are not ill and deserve to be in class," Martin told the Boulder Daily Camera. "I said, 'This is nuts. ... My kids have a legal right to have access to public education."

Just hours after Martin's call to complain, she got an apology, and her children were let back into school, according to Briggs Gamblin, communications director for the Boulder Valley School District.

The school district now has a comprehensive guide developed in consultation with public health experts on swine flu suspicions in school: Monitor your health if you've been traveling in a high-risk area, and quarantine your family if you show symptoms, especially a fever above 100 degrees Fahrenheit.

"There's been an apology," said Gamblin. "It was an overreaction and it was made with the best of intentions."

Over about a week, the world saw some examples of possible knee-jerk reactions to reports about swine flu. People have upset their annual school exams, vacations and more over a virus that a recent Harvard School of Public Health Poll shows the public doesn't completely understand.

The Harvard poll showed 83 percent correctly said you can get swine flu from close contact with someone else who has it. But 34 percent of people incorrectly thought you could get the flu by coming in contact with pigs, 29 percent incorrectly thought you could get the flu from an infected person who's more than 30 feet away and 13 percent incorrectly thought you could get it from eating pork.

The Web site for elementary schools, individuals and doctors who suspect swine flu lurking about.

But among the estimated 46 percent of Americans who are concerned about getting the swine flu, some have gone farther than others in their caution.

The following is a list of some questionable swine flu reactions so far.

A tourist from New York at the Tijuana-San Diego border where thousands cross daily, told Agence France Presse that he debated whether to cross into Mexico.

"I'm from New York, came to California for holidays and I wanted to cross to Mexico. But 10 minutes ago, I received a call from my cousin trying to alert me not to cross," the man told AFP. "I'm not sure now. I don't know what the flu is. But in any case, I can go and come back."

Borders saw roughly half the traffic they normally did, according to reports by Reuters, AFP and the El Paso Times.

But those who did travel across the borders gave reasons that defied the travel advisory in logic and in actions.

"The business owners near the bridges in South El Paso tell me a lot of people from Juarez are coming over to El Paso, although not necessarily to shop," Alonso Flores, operations director at the El Paso Central Business Association told The El Paso Times. "They feel safe here, and they can take off the [medical] masks. They're not allowed to mill around over there, so they're coming here to do that, hang out."

"This describes an interesting behavior that the CDC is worried about," said Schaffner. "Some experts think that by wearing the mask people will do things they otherwise wouldn't that would put them at risk."

Schaffner hopes people still wash their hands, avoid public places if they're sick and keep away from sick people, whether wearing a face mask or not.

Egypt is the only country in the world so far to order a mass pig slaughter in light of the swine flu and quickly fell under criticism for the decision.

Although pork is banned in several predominately Islamic countries, pigs in Egypt largely are owned by the 10 percent Coptic Christian minority population living amid a Muslim majority that does not eat pork for religious reasons.

At one large pig farming center just north of Cairo, scores of angry farmers blocked the street to prevent health ministry workers in trucks and bulldozers from coming in to slaughter the animals, according to the Associated Press. Some pelted the vehicles with rocks, and shattered windshields -- and the workers left without killing any pigs.

Schaffner says the association between pigs and the swine flu (H1N1-09) virus has more to do with a "laboratory anomaly" of the virus and how it developed than anything to do with what's happening between humans and pigs.

"There's no suggestion that there's active transmission from pigs to people at this time," he said.

MTV reality show stars Heidi Montag and Spencer Pratt were seen on their honeymoon trip to Mexico wearing surgical masks on the beach, on the street and in each other's arms.

They might have been trying to set a good example, but their kiss in one picture likely would have rendered the flimsy protection against the flu even less effective.

Germ expert Dr. Elaine Larsen, told ABC News' "Good Morning America" that after a few hours, surgical masks start to get saturated and turn into a sponge-like device keeping germs close to the wearer's mouth.

Wet that sponge with a kiss and, well, one can imagine.

"I think that's really over the top," said Schaffner.

Schaffner said the couple's choice to wear the masks on a beach vacation -- kiss or not -- also goes well beyond public health recommendations.

"The first thing we should recognize is that surgical masks are designed to keep the surgeon's germs out of the wound of the patient," said Schaffner, who explained doctors really don't have a measure of how effective the masks are at keeping germs away from a healthy person.

"That's why the CDC does not recommend their [surgical masks] routine use."
