_Editor’s note: The toll of the coronavirus grows, with California under a state of emergency, and more than 150 cases and 11 deaths reported in the U.S.. Also, more than 300 million school
children worldwide are facing closures of their schools. What does this mean for you in your personal life? We asked Brian Labus, professor of public health at the University of Nevada Las
Vegas, about what kinds of physical contact are safe while COVID-19 is spreading._ We are exposed to numerous viruses from our day-to-day interactions with other people all the time.
However, our risk of being infected by a simple greeting usually isn’t in the forefront of our minds. The spread of COVID-19 has changed that. Conferences have banned handshakes, churches
have changed their worship services, and even politicians have changed the way they greet each other. But what’s the risk in a simple hug or a handshake? If someone’s hand is covered in
virus because they coughed into it right before they shook your hand, it is no different than handling their dirty tissue. Your hand is now contaminated, and if you absentmindedly rub your
eye or touch your mouth, you have potentially just infected yourself. You are relying on other people to wash their hands in order to protect you, but we know that people are terrible about
hand-washing, even after using the bathroom. The simple fact is that we put ourselves at some risk of infection every time we interact with other humans. So what should you do if a stranger
extends their hand to greet you or a friend tries to hug you? Pulling your hand away from that potential big sale or recoiling in shock from your friend’s embrace is probably not the best
approach. It’s about balancing the risk of infection with the negative consequences of breaching social etiquette. Health experts around the world have been recommending that people reduce
unnecessary physical contact with other people, such as shaking hands or kissing on the cheek. Even the French have recommended no cheek kissing. You can still greet each people warmly and
politely without touching them, by bumping elbows or fists, tapping feet (the “Wuhan shake” popular on social media), simply waving hi, or one of the many other creative suggestions that are
popping up online. This isn’t about making extreme changes to our social interactions; it’s about taking simple steps to help reduce your risk of disease. The other important step in
protecting yourself is to frequently wash your hands or use hand sanitizer if soap and water are not readily available. This is a critical part of protecting yourself, as you can’t introduce
a virus into your mucous membranes if you have removed it from your hands. As this outbreak progresses, maybe we will see the refusal to shake hands not as a snub, but as an expression of
genuine concern for each others’ health. If you are worried about offending someone by using hand sanitizer after shaking someone’s hand, offer them some of your sanitizer as well. Change
the conversation and help make having clean hands something that not only important to you, but socially desirable as well. [_You’re smart and curious about the world. So are The
