Changing Behavior to Prevent H1N1

The H1N1 virus has disrupted the sanctity of service. At Salt Lake City Catholic churches, there's no shared cup at communion, no holy water by the front door because dipping fingers spreads germs.

"We're suggesting that people not shake hands or make physical contact," said Scott Dodge, a deacon.

In Charlotte, where hundreds have contracted H1N1, they're fighting back at football games with Purell - every fan gets a squirt.

In Glen Cove, N.Y., one school went so far as to put a ban on all touching, though it's tough to stop every chest bump.

Many people are trying to think outside of the box, reports CBS News correspondent Jeff Glor.

A recent study found hand washing does cut down on sick days. Schools that practice bad hygiene lose students for three days a year. Good hygiene - 2.4. So it may help fight some germs.

But epidemiologist Peter Palese said that for fighting the flu, it might not make that much difference.

"I think washing hands is important, but maybe not for the influenza virus transmission. Influenza virus gets transmitted mostly through the air," Palese said.

Longtime anti-handshake advocates are taking no chances.

Real estate magnate Donald Trump says he hasn't gotten a cold or the flu in 15 years.

"I've been on this bandwagon for many years," Trump said. "People shouldn't be doing it."

The king of the handshake deal doesn't refuse to shake hands, but he prefers not to.

"I have people come into my office and they shake my hand, and then I say, 'How are you feeling?' and they say, 'Oh, I'm so sick, I have the worst cold,' or 'I have the worst flu,' and I say, "What did you shake my hand for?'" Trump said.

While this wave of worry likely won't end a tradition that began in the second century B.C., it's doing wonders for the hand sanitizing business - sales are up 41 percent in the last six months. It may not be the best defense against H1N1, but they're still cleaning up.
