Coronavirus: How To Keep Your Home Sanitized

As the Coronavirus pandemic heats up worldwide, the epicenter of the disease has switched to the United States.

While the disease started in China and Italy has had the most deaths, we here in the USA reached the point of having the most total reported cases as of Thursday, the 26th.

While some are trying to blame this on the slow start we as a nation have had in testing, in the eight days before reaching the most total reported cases, the US tested more people than South Korea had in the previous eight weeks. That’s at least somewhat significant, in that the population of the United States is over six times larger than that of South Korea; so it shouldn’t be surprising that it has taken us more time to reach a significant number of tests. We’ve had to produce a lot more kits to test with.

On the flip side of that coin, the slow start in testing has resulted in more opportunities for people to spread the disease, before being tested. But considering the long incubation period for this disease, I’m not sure that would have made a difference.

What is making a difference is the lockdowns that much of the country is currently under. While this may not have a significant impact on the total number of people who end up with the disease, it is projected to have a huge impact on the infection rate, slowing down the curve of how fast the disease spreads. That is enough to make it worthwhile doing so that we don’t end up with the same problems that Italy is having.

According to the latest figures, over one
percent of Italy’s population has come down with COVID-19. That may not sound
too bad to you, but the scary figure is that over 10% of the people who have
come down with the disease in Italy have died from it. In fact, the ratio of
deaths to those who have been cured stands at 8:10, the highest in the world.

There are many reasons why Italy has fared
so poorly in this pandemic, including having a population with the second
oldest average age in the world. But the prime reason is that their medical
community has been overwhelmed by the virus and is unable to treat all those
who need it. They started triaging off anyone 80 years of age or older and have
since lowered that age to 60 years of age. If you are more than 60 years old
and come down with the virus, they just send you home – no testing, no

That’s what our government is trying to
avoid here. While we have some of the best medical care in the world, right now
New York City has less than 1/5 of the intensive care hospital beds that they
need to treat critical COVID-19 cases. Without the seemingly drastic measures
our government is taking, we could see that same thing nationwide.

The Best Solution – Don’t Get Sick

It may seem like a trite observation, but the best thing that any of us can do is to avoid getting infected. That may be harder to do than it seems. When you’re trying to avoid something that’s so small that you can’t even see it, the only way you can avoid it is to assume that everything is contaminated. That may seem paranoid, but the real question in a case like this is, “Am I being paranoid enough?”

There are cases of COVID-19 in every state
in the country and in every country in the world, with the exception of
Antarctica. So unless you’re moving to Antarctica this week, avoiding the
disease is becoming harder and harder. In some states, like Nevada and Montana,
the low population density provides some protection. In addition, the Southwest
has an advantage, due to the heat and bright sunlight (which kills the virus).

For the rest of us, if there is one
reported case of COVID-19 in your county, I’d suggest that you assume that your
entire county is contaminated. That’s what I’m doing. Again, I know it’s
paranoid; but is it paranoid enough?

With that in mind, how do we make sure that
the virus stays out of our homes and that we don’t become infected by it?

The advice that has been put out by our various government agencies is good in this regard. It originated with the CDC (the Center for Disease Control and Prevention), which is widely recognized as the world’s premier medical research institute for infectious diseases. But as I’ve been studying the disease and the spread of disease in general, I’ve come to realize that those measures are not enough. Those measures are good to help us avoid catching the disease directly from others, but they don’t do much good to help us avoid picking up the virus from inanimate objects.

According to the latest information out of
the National Institute of Health, the 2019-nCoV virus can survive for up to
three days on some surfaces (this information has not been peer-reviewed yet)
and can linger in the air from aerosol transmission for up to three hours. This
information supersedes earlier information that projected a survival time of up
to nine days. But that information was based upon a different coronavirus than
the one we are faced with today.

Here’s the problem, as I see it; with the
amount of time that the virus can stay alive, outside a human host, there’s
much more chance of us catching the virus from picking it up off a surface,
even with the current restrictions, than there is of us catching it directly
from someone. If we could actually keep from touching our faces, we might be
able to dodge the bullet, even if we pick it up on our hands; but that’s much
easier said than done.

Perhaps the most dangerous thing that any
of us are doing today is to go to the grocery store. Chances are, someone has
been in that store before you, who is infected with the virus and doesn’t even
know it. That means that everything they touch is likely to have the virus on
it; not just the handles of the shopping carts, but the products on the shelves

That’s what we have to keep from getting
into our homes.

Let’s Talk Masks and Gloves

The Surgeon General and other medical officials have asked the American people to stop buying surgical and N-95 masks because there aren’t enough for all the medical professionals who need them. Apparently, the government’s stockpile of 100 million medical masks wasn’t restocked after the Swine Flu pandemic in 2009. We’re now suffering the results of that bad decision.

Regardless of how we’ve gotten here, we
have to deal with the situation as it is; there aren’t enough masks to go around.
So the medical community has asked that we not buy them, stating that those
masks really aren’t going to keep us from getting infected anyway. The reason
that doctors wear surgical masks isn’t to protect them from catching anything
the patient might have, but to protect the patient from any germs the medical
personnel might have. In surgery, this is a major concern.

I won’t argue with those medical
authorities. I’m sure they know more than I do. On the other hand, I can’t help
but see that in the countries which are being held up as an example for their
handling of the pandemic, everyone is wearing masks. So apparently the masks
are helping. I don’t think that’s because it is helping keep people from
breathing the virus in, but rather it’s helping keep infected people from
breathing and coughing the virus out.

At some point, I believe that it will be necessary for us to all don masks; at least for when we are out in public. Hopefully, the supply chain will catch up and the supply of masks will soon be in place to allow for that. In the meantime, we must depend on social distancing.

I’ve taken to wearing disposable rubber
gloves when going out in public, especially when going to the store (which is
about the only place I’m going). The gloves I’m using came out of my workshop,
where I use them for things like staining wood and working with fiberglass. I
bought them at Harbor Freight, and as of the last time I looked, they still had
lots of gloves in stock, even though their supply of masks was decimated.

The purpose of the gloves is to avoid picking up any viruses off of the packaging. Since I don’t know if things in the store are contaminated and I don’t have any ready way of testing, I have to assume that they are. As far as I’m concerned, wearing disposable gloves is better, because it protects my hands from picking up the virus, rather than depending on my ability to wash it off.

Once I leave the store, the gloves come
off, turning them inside-out in the process, and are deposited in the garbage
can. I’ve got plenty more gloves for the next time I go to the store.

One other little detail I’ve come up with, which the half-empty shelves in our grocery stores make easy. That’s to pick up an item from the back of the shelf, rather than the one in the front. That way, there are probably fewer hands that have handled that package. Please though, don’t make a mess in the process, just reach around through the empty area on the shelf and only touch the package that you’re going to take. Be considerate of others.

Decontaminating the Things I Buy

Anything I’m buying is assumed to be
contaminated, whether I buy it in the local grocery store or order it online. I
have no way of knowing whether the person who picked and packed that order was
infected and contagious or not; therefore, I must assume that they were.

There are several different ways of
decontaminating purchases, depending on what it is and how it is packaged. But
to start with, I need two decontaminated work areas; these can be two halves of
a table I’ve decontaminated or the floor of my kitchen and the countertop, with
the counter decontaminated. In either case, items that haven’t yet been
decontaminated are kept separate from those which have been.

The tools for this process are mostly paper
towels and disinfectant spray. The paper towels should be soaked with the
disinfectant, just about to the point where you can squeeze it out. You can
either choose to wear disposable rubber gloves or not. Either way, you should
wash your hands thoroughly before and after the process.

You’ll also want to set out open containers
to put the food that you’re going to repackage into. Do this, before bringing
the grocery bags in from your car, while you are disinfecting your
decontamination area.

Items that are packaged in cans, bottles, boxes, and bags can be decontaminated by wiping them with wet paper towels. This can even be done with meat that has been packaged by the butcher. However, a more secure method is to remove the contents and repackage them in containers that you have kept at home, which you know are not contaminated. That won’t work well for canned and bottled items, but it will for things like bagged rice and beans, or packaged cookies.

For items that are bagged inside of a box,
like breakfast cereal and crackers, you can open the box and remove the inner
bag. That bag will be clean, even if the outer box isn’t. So all you have to do
is to open the box and dump out the clean bag into your decontaminated food

Fruits and vegetables which are packaged in plastic bags can be stored as-is, once the plastic packaging has been decontaminated. But produce that has been put in mesh bags, berries in plastic boxes or product that you select and bag yourself must all be assumed to be contaminated. Rather than using the disinfectant spray on them (which may not be good to eat), wash them in the sink with soap and water, just like your hands, being sure to rinse them well to remove the soap.

Once all your food is removed from the packaging, gather up the packaging and the grocery bags and throw them away in the outside garbage can. Then come inside and disinfect your hands and the area that you were using as a holding area for the food to be decontaminated.

During this entire process, you should only touch the outside of the packaging and your disinfectant soaked paper towels. Don’t touch anything inside the packages, as you might be transferring the virus to the outside of the packages to the food inside with your own hands. If you have to close containers, wait until you have finished decontaminating the food, have disposed of the packaging and have disinfected your hands.

Decontaminating Food with Sunlight

It is a known fact that sunlight is a
strong disinfectant. Actually, it’s the ultraviolet (UV) light in sunlight that
is. Sunlight is uniformly deadly to both bacteria and viruses. For bacteria,
only 10 seconds of exposure to direct sunlight is needed to kill them. However,
no such definitive study seems to have been done for viruses. So, while it is
known that UV light will kill viruses, it is not known how much UV is required.

Nevertheless, we can use UV light to
decontaminate the food we bring home from the grocery store, at least that
which doesn’t need to be refrigerated. All that you have to do is set your
purchases out on a table or even in your driveway, making sure that they are
spread out far enough so that nothing is in the shadow of anything else. After
a while, go back and turn the items 180 degrees, so that the other side, which
had been in shadow, is exposed.

Once done with this UV decontamination
process, disinfect your hands and then repackage the groceries in new bags to
bring them into the house, not the ones you brought home from the store; they are
assumed to be contaminated and must go in the garbage.

Something similar can be done with any
shipments you receive at your home. First leave the package in the sun for UV
decontamination, just like I discussed for your groceries. Then open the
package and leave the item in the sun, repeating the process while you throw
away the outer package. In this way, if the person who picked and packed the
package was contagious, you won’t be bringing the virus into your home.

Decontaminating Your Clothes

Finally, you have to assume that any
clothing you wore out in public is contaminated and treat it that way. The best
thing to do is take it off, once you have finished decontaminating your hands,
and put it in the laundry to be washed. Don’t wear it again, until you wash it.

But is just washing it enough? Again, am I
being paranoid enough?

There are a couple of different ways that you can ensure that your clothing is decontaminated. The first is to use chlorine bleach in your wash. Of course, that only works for whites or clothes that you don’t care about become discolored. For the brighter colored clothes, that’s not a good idea.

So will “color-safe” bleach work? Surprisingly, it will. The whitening agent in color-safe bleach is hydrogen peroxide, which is also a strong disinfectant. You can disinfect a load of clothing by adding one cup of hydrogen peroxide per load.

If you can’t find hydrogen peroxide or
color-safe bleach, you can add 20 Mule Team Borax to your wash. This old-school
laundry additive combines with the water in your wash, to create hydrogen
peroxide, making it ideal for disinfecting your clothes.

Finally, to be extra sure that your clothing is fully disinfecting, you can dry your clothes on an old-fashioned clothesline, where the UV from the sun can reach it. While sunlight won’t work as effectively as a disinfectant on cloth, as it does on harder surfaces, it still works. Besides, your clothes will be hanging out there for a while, giving the sun plenty of time to work.
