Hello, social distancing. Goodbye, handshakes?

By Omar Younis and Clare Baldwin

LOS ANGELES (Reuters) – It started centuries ago as a symbol of peace, a gesture to prove you weren’t holding a weapon, and over time it became part of almost every social, religious, professional, business and sporting exchange.

But the new coronavirus has forced a rethink of the handshake. No matter how friendly, it is an exchange of potentially infectious microorganisms.

“Hands are like a busy intersection, constantly connecting our microbiome to the microbiomes of other people, places, and things,” a group of scientists wrote in the Journal of Dermatological Science. Hands, they said, are the “critical vector” for transmitting microorganisms including viruses.

But if it is no longer automatically acceptable, what will replace the handshake as a fixture of post-coronavirus social etiquette? A fist or elbow bump? Maybe a traditional Japanese bow or hat doff? How about Spock’s Vulcan salute from Star Trek?

We are social beings. When we meet one another, we press flesh. We take our largest organ, skin, and mash it together with someone else’s – naked. In the middle of the coronavirus it has become clear just how intimate such a gesture is.

The human hand is fecund. We have hundreds of species of bacteria and viruses on our palms.

“Think about it,” says Charles Gerba, a microbiologist and public health researcher at the University of Arizona, who also answers to Dr Germ. “Every time you touch a surface, you may be picking up up to 50 percent of the organisms on that surface.”

Our hands can carry Salmonella, E. coli, norovirus and respiratory infections like adenovirus and hand-foot-mouth disease. And, given how frequently scientists find poop on our fingers and palms, our hygiene habits are far less fastidious than we think.

BACTERIAL EFFERVESCENCE

We can’t see any of this with the naked eye.

And so we rely on scientists with agar plates to make visible the arching, spiraling, exploding patterns of bacterial effervescence that show just what our intermingling of fingers risks, something so simple as a handshake rendered in terrifying technicolor.

Scientists can also show us viruses. Those must be studied in animal cells, in a mosaic of tiny semi-circles that scientists often stain purple or red.

The cells are lovely, says Gerba, “and then when they die, they become colorless.”

Gerba studies the movement of viruses. He’ll put a virus on an office doorknob or in a hotel room or someone’s home.

He says it takes just four hours for a virus on an office doorknob to reach half the hands and half the surfaces in an office building, or about 90 percent of the surfaces in someone’s home. A virus in a hotel often moves from room to room and sometimes to nearby conferences.

Gerba says he himself stopped shaking hands during the first SARS outbreak, in 2003. “I always say I have a cold,” he says. “That way I don’t have to shake their hand.”

Top U.S. infectious diseases expert Dr Anthony Fauci sees it the same way since the pandemic hit.

“You don’t ever shake anybody’s hands,” Fauci said this month. “That’s clear.”

LONG, HARD SQUEEZE

Handshakes have long been a way for humans to signal one another, and part of the ritual of seeking common ground.

“The handshake is what gets photographed at the time of any agreement,” says Dorothy Noyes, a professor of folklore at Ohio State University.

The long, hard squeeze of U.S. President Donald Trump and French President Emmanuel Macron in 2018 was a classic display of two males seeking dominance. Some handshakes, like the bouncing clasp of Chinese President Xi Jinping and Japanese Prime Minister Shinzo Abe, take months to negotiate.

Awkward or smooth, handshakes are a hard habit to break, even if we want to.

Minutes after announcing a ban on shaking hands to combat COVID-19, Dutch Prime Minister Mark Rutte enthusiastically pumped the hand of Jaap Van Dissel, the head of the Dutch Centre for Infectious Disease Control.

“Sorry, sorry! No, that’s not allowed! Let’s do that again,” Rutte said, breaking into a laugh.

No hugs, handshakes as U.S. churches take new precautions against coronavirus

By Rich McKay

ATLANTA (Reuters) – With a wide smile and arms outstretched, but quickly dropped into double elbow bumps, James Harper warmly greets fellow congregants at Our Lady of Lourdes Catholic Church on Sunday in Atlanta’s Old Fourth Ward neighborhood.

“We’re all tight here,” said Harper, 51, a salesman. “Normally it’s nothing but deep hugs. But it’s a different day now.”

Churches across the United States are advising parishioners to avoid direct contact with fellow members as an oft-reiterated warning against spreading the coronavirus, which emerged in China last year and causes the sometimes deadly respiratory illness COVID-19.

At least 19 people have died out of about 450 reported cases in the United States. The outbreak has killed more than 3,600 worldwide.

Reverend Jeffery Ott, pastor of Our Lady of Lourdes, said that the biggest change on Sunday was omitting the ceremonial sharing of wine in the common cup, or chalice, during the Holy Communion service, as well as receiving the wafer or bread in the hand only, not the mouth.

“Traditionalist may want the service, but this is not just the flu,” he said. “We are all responsible to stop the spread.”

The instructions, now widespread across archdioceses across the nation, involve changes to relatively new ceremonies, such as the exchange of peace, which was introduced in the 1960s, as well as age-old traditions such as Holy Communion that are at the core of Catholic ritual.

Thomas Groome, a professor of theology at Boston College and a former priest, said the new measures show how seriously the church is taking the risks of coronavirus.

“All of these things are traditions that many are sentimental about,” he said. “But none of these symbols are essentials to the church.”

Traditionally Catholics embrace or shake hands during the so-called “exchange of peace” while repeating the greeting “peace be with you.”

But the Roman Catholic Archdiocese of Atlanta is one of many that have told parishes to discourage physical contact during the ritual, which is designed to remind worshippers they are members of a community. Some dioceses want the “peace” ceremony eliminated all together until the coronavirus outbreak abates.

As an alternative to touching, the Archdiocese of New York is encouraging worshippers to wave at fellow parishioners during the greeting, said Joseph Zwilling, a spokesman for the archdiocese.

Groome said that at his church in Boston, the congregation nods or trades fist-bumps.

“This is the responsible thing to do,” he said.

In the Archdiocese of Miami, churches have been urged to empty the holy water fonts at the church doors as a precaution. When entering a church, many Catholics dip their fingers in the fonts and make the sign of the cross with the water which a priest had blessed. Experts say it is an obvious conduit for infection.

Keeping people healthy is more important than tradition, Reverend Ott said.

“Some of our older members might not like the changes but we have to be responsible,” he said.
