Don’ts and Dos on Coronavirus
by Jane M. Orient, M.D.
Some of the views expressed here are controversial. So, do ask your doctor. I hope you have one—not just the HMO or retail clinic
“provider.”

Don’t panic. That is always good advice. If you, like the world’s economy, operate on just-in-time inventories, and did not take advice to
stock up 3 weeks ago, do not join a mob at a big-box store. Somebody there is no doubt infected. Plus, there’s the risk of getting trampled
or injured in a fist fight over the last roll of toilet paper. Most of the world survives without that luxury good. If you have no rice or beans or
pasta in the pantry, that is more serious, but you should still avoid mobs if at all possible. Take-out and drive-through places are booming.
Don’t treat fever without a doctor’s advice. Fever is not a disease. It is an important defense mechanism. Very high fevers (say 105
degrees) can cause brain damage, and children can have seizures. But don’t pop Tylenol or ibuprofen at the first sign of fever. Many of the
casualties in the 1918 pandemic might have been caused by heavy use of aspirin. Like aspirin, popular nonsteroidal anti-inflammatories
(NSAIDS) such ibuprofen also have detrimental effects on blood clotting. Try lukewarm sponge baths for comfort.

Don’t rush out and get a flu shot. I know, a lot of doctors and public health authorities urge everybody to do this. Influenza can kill you, and
the flu shot decreases that risk by 30% to 60%—but there is evidence that it can make COVID-19 worse, both from the earlier SARS
epidemic and lab research. Like with so many things in medicine, we have to play the odds.

Don’t go to the emergency room or urgent care unless you are severely ill. There will be sick people there, and you might catch
something. You also might end up with a big bill, say for a CT scan you didn’t really need. And if you have the flu or a cold or COVID-19,
and don’t need IV fluids or oxygen, they can’t do anything for you. Telephone advice lines could help greatly.

Don’t go to events that are crowded, especially indoors in poorly ventilated rooms. Staying home is good.

Don’t demand to be tested and rely on the results. The tests are still in short supply and not very accurate. If you are at low risk, a
positive test is likely to be a false positive. And if you are infected, the test may be negative at first. We need much more testing—mainly
for public health monitoring.

Don’t waste. Expired medications are probably still good. Most drugs or essential ingredients are made in China, and supplies are
running out. Masks (also mostly made in China) are meant to be disposable, but likely can’t be replaced (see below).
Don’t touch your face or your eyes. That is very hard—preventing that is one function of a mask and eye protection.
Don’t fall for internet scams, or malware. Hucksters will always be around to try to profit from panics. A new type of malicious virus is
embedded malware in sites that come up on a search for information. (If you want to find the Johns Hopkins University dashboard of
cases and deaths, go to the university’s website, don’t Google “coronavirus map.”)

Now for some dos:
Do prepare to take care of yourself and your family.
Be sure you have a fever thermometer, disposable gloves, plastic garbage bags,
and cleaning supplies. A pulse oximeter, available in many places for around $40, is good to have to check oxygen levels.
Do clean and disinfect surfaces such as doorknobs, telephones, computer keyboards, toilets, and countertops often. Virus can persist
there for days.

Do remember that sunlight is the best disinfectant. If you don’t have a pocket ultraviolet lamp (they are or were available on amazon), try
putting things like masks or paper currency out in the sun. The idea should be rigorously tested, but in times of need, you may have to
guess.

Do wash your hands often and use hand sanitizer. With SARS-CoV-2, most disinfectants work, including 70-percent-alcohol-based
sanitizers.

Do put a mask on sick people if you can.
For protecting yourself you need a minimum of an N95 mask and eye protection.

Do take your vitamins. Most people may be vitamin D deficient. Your need for vitamin C escalates with infection. Some 50 tons of
vitamin C was shipped to Wuhan, and studies of effectiveness are underway.

Do get your essential prescriptions refilled for 90 days—the supply chain depends on China. If your managed-care plan won’t pay,
consider paying cash. You may be able to get a good price with a coupon from goodrx.com.

Do protect your immune system, with adequate sleep, exercise, fresh air, and diet, especially avoiding sugar if you feel ill.

Do help your neighbors, and be responsible about protecting others as well as yourself from contagion.
