COVID-19: The numbers donʻt look good
Anybody whoʻs still suggesting this
whole COVID-19 thing is overblown...theyʻre lying to you, or theyʻre
misinformed.
It is in fact frightening, and fast
getting worse. The United States is still at the start of the upward trend in
infections.
Consider this fact that you havenʻt heard
on the news: The European Union now has had three times more cases per
capita than China.
Here are the numbers: China has had
81,000 cases, and has a population of 1.4 billion. That works out to 57.5 cases
per million people.
The European Union has 69,900 cases
and a population of 446 million. Thatʻs 157 cases per million residents—three times
worse than China.
The United States so far has just 6,420
cases in a population of 331 million, or 19.4 cases per million.
Chinaʻs case load has dropped
dramatically. They did that with draconian measures, including aggressive
quarantine, bounties paid to people who turned in quarantine violators, tracking
peoplesʻ cell phones and requiring everyone wear masks whenever outside.
South Korea had a severe outbreak, and
approached it in a very different way, with the most expansive testing program
in the world: More than 270,000 of its residents were tested as it tracked down
and quarantined anyone who was sick with COVID-19.
South Korea has 8,320 cases. That
works out to 162 cases per million of its 51.5 million residents. But it has
dropped its number of new cases dramatically. The magazine Science printed a story today on how South Korea did that.
As I write this on March 17, 2020, Italy
has the worst caseload in the European Union and perhaps the world—521 cases
per million residents. (31,500 cases in a population of 60.5 million.)
Just
looking at the numbers suggests much worse is yet to come for the United
States. Our population is about 328 million.
If we are able to limit our outbreak
to Chinaʻs size, weʻre looking at 19,000 cases. (57.5 times 328 million.)
If we can keep it to Koreaʻs, then
itʻs 53,000. (162 times 328 million.)
But if we get to Italyʻs situation,
itʻs 171,000 (521 times 328 million.)
One issue is that while China and
South Korea used two different strategies to begin to get a handle on the outbreak,
the United States has been using neither. Not aggressive, almost punitive
quarantine measures like China. And not aggressive, intrusive testing like
Korea.
Our national hope seems to be that a
combination of voluntary isolation measures and a moderate testing protocol
will do the trick.

COVID-19 Fake News: Bogus "cure" rumors, debunked here
The bogus home cures for COVID-19 are showing up all over.
Fortunately
most wonʻt hurt you, and some might even ease symptoms a little, but not cure
you. That said, some of these crazy "cures" can kill you.
Hereʻs one
lie: Gargling with salt water will wash the disease out of your throat and
youʻll be better. Or gargling with warm salt water and vinegar will kill the
virus.
Simple logic
reminds you that the virus isnʻt only in your throat. Itʻs also in your nasal
passages, in your lungs, in your blood, and even in feces. Gargling isnʻt going
to have any impact on most of those locations.
Gargling with
or drinking bleach, which some have suggested, has the additional downside of
being dangerous as well as ineffective. It can burn your throat and stomach, it
can collapse your blood pressure, it can put you into a coma. Donʻt do it. Hereʻs some information from the New York State health office. Also, wiping or
spraying down your body with a bleach solution may clean your skin, but it wonʻt
have an impact on the disease inside you.
Eating garlic
or drinking garlic soup might keep people away from you due to the smell—which
is an interesting take on social distancing—but thereʻs no evidence it helps
with the disease. Here is that one and a few other myths from the World Health
Organizationʻs website.
Drinking
large amounts of alcohol or water wonʻt prevent or stop the disease. The World
Health Organizationʻs twitter feed debunks these theories.
There are
predatory personalities online, on radio and on TV who promote bogus cures of
several kinds. Often, youʻll find theyʻre selling their special
"cure." Theyʻre getting rich on the backs of the sick. Some have
already been told by government agencies to stop with the fake cures.
Fortunately,
there are several websites that are actively responding to malicious and erroneous
medical information about this outbreak. Hereʻs one.
The upshot:
donʻt do stupid stuff just because some stranger (or even a friend) told you it
might work.
If you do get
sick, here are some tips from the professionals at the Centers for Disease Control and Prevention.

COVID-19: Kaua`i has its first confirmed cases, and debunking fake news--folks, the barges are still coming
Kaua`i today was
confirmed to have its first active cases of COVID-19, in a tourist couple who
are being kept in isolation.
The couple is at an
undisclosed site overseen by Kaua`i County and being monitored by the state Department
of Health. The case is being managed according to protocols set up in advance
in anticipation of the event.
The confirmation, which was announced in a mass email from Kaua`i County a couple of hours after midnight, was
based on testing of the couple performed yesterday (Friday, March 13, 2020).
Meanwhile, the stateʻs epidemic rumor mill continues to churn.
One of the most active
rumors, that cargo to the island is being disrupted, has spawned new runs on
supplies.
"I have never
seen Costco so full. They had lines snaking away from the checkout counters,
some of them all the way back to the pharmacy," one friend told me Friday
afternoon.
At Safeway, two women
asked me whether it was true that Young Brothers barges have been blocked from
coming. Others reported rumors that the harbors have been closed.
None of that is true.
I talked to store officials, who insist their supply lines are intact, and harbors
and shipping officials. Food and toilet paper are still making their ways to
the island.
What the panic buying and hoarding has done is move supplies from store shelves, where people can get them as needed, into peoplesʻ home larders, where excess supplies are not available to people in need.

Matson took the step
of issuing a press release in response to the rumors:
“Matson intends to maintain all service schedules as normal with three arrivals a week to Honolulu and twice a week calls to each neighbor island port.

Young Brothers, the
inter-island barge service, issued its own statement:
"There are currently NO changes to sailing schedule or cargo acceptance at all ports. YB will continue to monitor COVID-19 and its impact to the State."

COVID-19 Fake News: Stuff people are saying about the disease thats just bull
There is lots
of information about COVID-19 out there, and some of it is bad information.
Hereʻs some
of the stuff Iʻve been hearing thatʻs not true, or not entirely true.
Q. A friend
asked whether, once youʻve had the virus, youʻre immune in the future.
A. The answer
is, probably, but not certainly.
Youʻre
generally immune to a virus after having gotten it—at least for a while.
However, there have been rare cases in which people have appeared to be over COVID-19,
and then got sick again. Was it simply a relapse of the original infection or a
new one? Thatʻs not yet clear.
There is also
indication that the virus has evolved, at least in China, and that there are
now at least two versions of COVID-19 out there. If youʻve had one, you might
still be susceptible to getting the second. Hereʻs a link to a scientific paper
on that.
The Centers
for Disease Control says this: "The immune response to COVID-19 is not yet
understood. Patients with MERS-CoV infection are unlikely to be re-infected
shortly after they recover, but it is not yet known whether similar immune
protection will be observed for patients with COVID-19."
Q. Another person
said flu goes away in the summer, so this will be gone by mid-year.
A. Donʻt count on it. This
disease has not been around long enough to know. Hereʻs what the Centers for
Disease Control says about that:
"It is not yet known whether weather and
temperature impact the spread of COVID-19. Some other viruses, like the common
cold and flu, spread more during cold weather months but that does not mean it
is impossible to become sick with these viruses during other months. At this time, it is not known whether the
spread of COVID-19 will decrease when weather becomes warmer. There is much more to learn about the
transmissibility, severity, and other features associated with COVID-19 and
investigations are ongoing."
Q. A
co-worker told me he read that if itʻs a dry cough itʻs COVID-19, but if itʻs a
wet cough itʻs the flu.
A. Wrong.
(Sometimes.)
As this guide from Johns Hopkins Medicine notes, thereʻs no sure thing with symptoms. A dry
cough occurs most often in COVID-19, but not always. Same with fever—some patients
have one, some donʻt. Same with soreness and tiredness. Same with shortness of
breath.
A World Health Organization study in Chinaʻs outbreak found that fever occurs 88 percent
of the time, dry cough in 68 percent of
cases, fatigue in 38 percent, sputum
production in 33 percent, shortness of breath in 19 percent, sore throat in 14
percent, headache in 14 percent, joint pan in 15 percent, chills in 11 percent,
nausea or vomiting in 5 percent, nasal congestion in 5 percent, diarrhea in 4
percent, and coughing up blood in 1 percent and and watery or inflamed eyes 1 percent.
Q. Someone
asked, if I get tested, will I know for sure that I am or am not infected?
A. If you
have symptoms and a positive test, youʻre infected. The test can confirm that
the disease youʻve got is not a cold or flu or other virus and is COVID-19.
If you have
no symptoms and you can get someone to test you, chances are it will be
negative. But that doesnʻt necessarily mean you donʻt have it. It could mean you donʻt. Or it
could mean youʻre infected but havenʻt been infected long enough to test
positive.
"As with all currently available tests, it’s
not yet clear how long a person needs to be infected before testing positive,
or whether someone who's infected could be identified by the test before
displaying symptoms."
Q. If I get sick,
I can only infect others while I have active symptoms.
A. Wrong. You
can infect people a day or two before your active symptoms show up,
and you might be able to pass the virus to others for a week or more after youʻve recovered.
This German study found active viruses for many days after symptoms disappeared.

Drying laundry efficiently: air dry is best, but in a dryer long and cooler is more efficient than short and hot.
A friend
asked a question about energy use in clothes dryers.
The discussion started
with the understanding that if you can hang your clothes in the breeze on a
clothesline, youʻve found the most energy efficient way to dry your laundry.
But if you
need to use a dryer, she asked, is more energy efficient to run the dryer
longer at a cool temperature, or shorter at a higher temperature.
There are all
sorts of variables in this calculation. Different types of fabric. Different
starting moisture levels. The more-dry setting (uses more energy) compared to
the less dry setting (more efficient.) Gas dryers with electric motors (more
energy efficient) versus all-electric dryers (less efficient.) And within those
categories, newer dryers that emphasize efficiency versus ones that donʻt.
But given
equivalent conditions, and assuming all-electric, it looks like running a dryer
longer at a slightly cooler temperature saves energy compared to running it
hotter shorter.
Thatʻs
because the heating requires so very much more electricity than the motor.
This paper
from the American Council for an Energy-Efficient Economy (ACEEE) found that energy savings are available from "using a lower heat setting to reduce
the energy spent heating air, cloth, and metal. The clothes get just as dry, though
drying time may be longer."
Thereʻs a lot
more in that paper, so if youʻre interested, read through it, or at least read
the recommendations and conclusions in the last four pages.
And this piece of research is old, but it was authoritatively done by the Oak Ridge National Laboratory,
and it also found that itʻs the heating that uses most of the power in a dryer.
The dryers back then were not all that different than those today, and ORNL
calculated that 91 percent of the energy was used for heating, and 9 percent
for all the dryerʻs other functions: tumbling, blowing and running the
controls.
The U.S.
Governmentʻs Energy.gov website comes to the same conclusion: "Use lower
heat settings in the dryer. Even if the drying cycle is longer, you’ll use less
energy and be less likely to over-dry your clothes."
The site also
has lots of other tips on saving energy in the laundry arena.
