Here are preventive measures that people are considering at this time and some notes that are worth your time and attention.
Using hand sanitizer
It works. Use it often. Make sure it’s alcohol based. There are some “natural” products designed to be less drying to your hands. These do not work.
Cleaning hand towels
Wash them often, too.
It’s not a clearly threatening practice, and physical touch has its own value to consider, as do gestures of respect. But consider alternative forms of greetings such as fist.
Touching your face
Avoiding touching your face is a nice idea and would be very effective, but no one is going to stop touching their face.
Here’s an unproven suggestion from me that transcends this particular outbreak: All business and public spaces should turn their bathrooms’ doors around, so you push on the way out rather than the way in. If building codes or other safety codes prohibit this, install a foot pull. If none of this is possible, at least put the trash can for paper towels outside the door so everyone can use a paper towel to touch the handle.
Disinfecting common surfaces
The crux of all the focus on handwashing is that you’re unlikely to get the virus from someone coughing or sneezing directly into your face. You are much more likely to catch the virus by touching something that someone else touched after coughing into their hand. This can partly be prevented by disinfecting surfaces.
The most commonly touched surfaces in homes and offices, especially shared spaces, are priority. Countertops, remote controls, and refrigerator handles should be disinfected regularly. That said, it’s very possible to become compulsive about this in ways that have their own risks. Any given surface is very unlikely to harbor a dangerous virus, so it’s possible to overdo this and waste a lot of time, resources, and concern. But if you’re the sort to typically only clean things that look visibly dirty, do consider the invisible.
This one warrants its own special note because phone screens may be the surface we touch the most. Other, similar coronaviruses are known to live on glass for up to four days. If you’ve been touching your phone with viral hands, then you do a beautiful job washing those hands, and then you touch your phone again, you may have just re-contaminated yourself. I’m not suggesting constantly cleaning your phone. The Centers for Disease Control and Prevention currently recommends once a day, though I don’t see how—if it’s worth doing at all—that would be often enough.
Masks seem logical as preventive measures because the disease is spread by respiratory droplets, which can travel simply by breathing but mostly distribute in plumes from coughs or sneezes. If you were sick and had to leave home for some reason, ideally you would wear a surgical mask. But even this precaution is far from perfect—the wearable equivalent of sneezing into your elbow instead of right in someone’s face. You’re still infectious and should behave accordingly. The World Health Organization has published recommendations for when civilians should use masks. But stockpiling also deprives other people who might have needed to follow those guidelines.
This week the U.S. surgeon general, Jerome Adams, urged Americans to stop buying face masks. This is a matter of short supply, should worst-case scenarios play out. In an ideal world, people who live with other people would have masks on hand when someone in the house gets sick, and they could help prevent close-quarters spread. But this is not an ideal world, and masks are needed for the people who are at the highest risk. When doctors, nurses, and first responders cannot work, new crises present themselves.
This mainly applies to people in remote areas where the town’s one grocery store could close down. Closing the store would be preferable to having sick employees report to work. In these areas, it’s always advisable to have a short-term supply of food (for any natural disaster), and this would be fair to treat similarly. Elsewhere, supply chains could be threatened, requiring certain shippers or grocers to close temporarily and certain foods to become scarce in certain areas, but none of this is cause for stockpiling.
Stockpiling prescription medications
Most U.S. prescription medications are made in China, whose own outbreak has raised concerns about medication supply chains. As of now, supplies have not been disrupted, and China is reporting declines in the spread of the virus. As with food, though, anyone who has a vital prescription and lives in a place where access would be affected by the single shutdown of a local pharmacy or a public-transit system, for example, should always have a small supply for emergencies. Health-care providers should help ensure this.
It’s always advisable to avoid travel if you’re sick. But no stay home directive is sustainable for long periods, and urgent life events will overlap with this outbreak. So guidance about this will be targeted, and ideally informed by easy screening and testing that can advise people with the sniffles whether they are fine to get on a plane or should urgently self-quarantine.
This is an extremely imperfect directive, as so many people’s jobs and other obligations make it impossible. But no single recommendation is perfect or universally applicable. And Americans have proved, flu season after flu season, that many workplaces are not accommodating enough of staying home. If workplaces are not accommodating, business may suffer even more in the long run, if more shutdown measures are taken.
Seeking medical care
This may be the most crucial question: When do mild symptoms warrant attention? Most people are not accustomed to seeking care or testing when they have a mild cough or runny nose. My hope is that, in the coming days and weeks, local and federal officials share clear guidelines for exactly how and when to seek medical attention early in the disease’s course. China’s containment measures depended on early detection that isolated people at the beginning of their infectious stage. Then again, we can’t have everyone with a cough and sniffles rushing to doctors’ offices.
South Korea, which has now identified some 5,000 cases, is pioneering drive-through screening clinics. The idea seems smart: There are no doorknobs to touch, no crowded waiting rooms with magazines that have been coughed on for months. Maybe most important, there is no paperwork to fill out and no cost. If an outbreak hits a major city, clinics and hospitals will likely be overrun with people who have cold and flu symptoms. Some of those people will need reassurance that they can go home and will be fine; others will need admission to a hospital; others may need an intermediate level of care, monitoring, and quarantine.
No matter your position, there are people who stand to lose much more than you do if they get sick. No matter how worried you are, there are people who are more worried. Look out for them, and help make sure everyone takes these basic measures and doesn’t panic. Societies break down when people fear one another as simply bipedal distributors of infectious agents. See people as allies in this unique moment of uncertainty.
