Plague of Fiery Serpents and COVID-19

Numbers 21 tells the story of the Israelites being affected by a plague of fiery serpents. Moses, by the direction of God, made a serpent of brass and asked the Israelites to look at it to be cured from the plague. While many of them did, many of them, thinking the thing was so simple, did not. Another example is in 2 Kings, chapter 5, where Pharpar is asked to bathe in the river Damascus seven times, a particularly dirty river, to cure leprosy. At first he was hesitent, but then, in verse 13, we read "Naaman's servants went to him and said, "My father, if the prophet had told you to do some great thing, would you not have done it? How much more, then, when he tells you, `Wash and be cleansed'!"

With this plague, we have been asked to do a few similar things, ones that even have the backing of science, but have been encouraged by religious leaders, including those of my faith, that of the Church of Jesus Christ of Latter-Day Saints. Of some note I can't find anything from any apostles, but it was certainly encouraged by example from the highest levels. We have been asked to wear masks to help prevent the spread of COVID-19. We have been encouraged to socially distance ourselves to minimize the spread. And while I haven't seen it explicitly stated, we are encouraged to get vaccinated when we are able to to even further prevent the spread.

While the effects of not following these simple guidance aren't as dramatic as that of the fiery serpents, I can't help but wonder how many people have had a similar reaction of that of the Isrealites, of not doing the thing because of its simplicity. It sadens me deeply that it seems like the evangelicals are those on the leading edge of anti-mask and anti-vaccine behavior. To me, these are those who are not looking at the brass serpent.

Masks and COVID-19

There are a lot of misconceptions out there about wearing masks, so let's talk about them!

div class="separator" style="clear: both;">

The first thing to mention is the conflicting information on masks. In Febuary and March, the guidance was to not use masks of any kind, to save them for the medical community. The reasoning was two fold. First of all, the medical community then had, and continues to have, a severe shortage in N95 masks. These are the only kind of masks that can filter virus sized particles with any kind of large success. As we continued to understand better, the advice was changed to encourage wearing masks all the time, be them cloth or otherwise. That continues to be the suggestion. That change of guidance has lead to considerable confusion, so let's clear that up now.

COVID-19 is transmitted primarily breathing water droplets that contain virus particles from a person who is infected. These water droplets are much larger than virus. This makes it much easier to to be absorbed by some kind of a mask. What changed primarily, at least at first, is that control over COVID-19 was lost. People frequently were contageous without showing symptoms. Thus, everyone could be considered potentially contageous. Wearing a mask, therefore, changed from being about protecting the wearer from getting disease to help keep others from getting sick, when you might be sick and don't know it yet.

Wearing a mask to prevent the spread of disease is nothing new. For years, if you arrive in a doctor's office and are sick and coughing or sneezing, they have requested that you wear a mask. This helps prevent you from spreading the disease you have. The fact that so many people have had COVID-19 and not even known it lead for a request to be made for everyone to wear masks when in public.

Mask wearing works by absorbing the droplets of water before they leave the vicinity of one's mouth. They very effectively will catch all of the spit droplets when one sneezes, for instance, and also work well for coughs and just when speaking. It turns out that stopping an air borne virus isn't required, just catching these droplets of mostly water will do just fine. This helps keep one from spreading the disease. Cloth masks work fine for this purpose. The latest studies show that their use is 90% effective against transmitting the disease, and about 50% effective against receiving it. In other works, everyone wearing a mask works as well as a low end vaccine!

For the record, every state, Republican or Democrat, either requires or requests that one wears a mask when in close proximity to others. In fact, as of now, every single state either requires the use of a mask when in public or at least recommends it. While President Trump has often been dismisive of wearing a mask, and was not photographed in public wearing one for 3 months after the recommendation was posted, face masks have been passed out at his political rallys, and at least at the entrance people were encouraged to wear them. The last two holdouts were South Dakota and Iowa, but even they are now recommending their use.

How effective is actually wearing a mask? Let's look at some data to compare. To do this let's compare similar states where one has a mask requirement, and one does not. Note that I chose these states without looking before infection rates, to show you what they are really like. The pairs, listed by mask required/ not required are Alabama/ Mississippi, Colorado/ Utah, Kentucky/ Tenessee, and Kansas/ Nebraska. To adjust for the sizes, I am going to use per capita numbers. I am using their total rates according to Worldometers.info

Let's start out with those not requiring masks. Mississippi is #12, Utah #6, Tenessee #10, and Nebraska #5. For those requiring masks, Alabama #15, Colorado is #32, Kentucky #30, and Kansas #17. In every instance, when compared to a nearby state, the state with the mask requirement has a lower rate of infections per capita. These states should be quite comparable as a whole, similar size of cities, mostly similar politics, the main difference is one requires wearing a mask in public, the other does not. Let's look at the raw numbers then from these states. The mask wearing ones have a per capita infection rate of 41049 per million, while the non-mask wearing has an average of 52915 per million. The death rate for mask wearing is 519 per million, while for non-mask is 644.

The bottom line is, wearing masks saves lives. I know, they are uncomfortable, trust me, I have to wear one every day, as I am required to go in to work and am required to wear a mask. But wearing a mask really does save lives. If these numbers hold true, as many as 50,000 US deaths or more could have been saved if everyone would simply wear a mask when in public.

How has President Trump really handled COVID-19?

It is pretty widely stated that President Trump has done a horrible job of managing COVID-19. Let's look in to how truthful that statement. As I usually do, we will talk about the actions coming out of the White House contrasted with what President Trump did via Twitter and other direct outreach efforts.

Let's start looking way back. COVID-19 was discussed about as a very harmful disease in China. For most of the month of January, it was only a concern to those who had been in China recently. The CDC began to start screening passengers coming from China on January 17, only 3 weks after the disease became publicly known. At that time, President Trump was informed of the disease, but was not particularly interested in it.

The CDC, under their own guidance, developed a test for the disease, but it was found to be defective, causing delays. Only the most likely cases were tested, primarily those who had either been to Wuhan, China, where it first was noticed, or had close contact with someone who had.

The White House did formally announce a Coronavirus Task Force at the end of January. The primary concern then was to get US citizens home from China safely, and keeping travelors out of the US. In fact, shortly thereafter, they began to restrict people from entering the US who had been in China, the first such restriction in 50 years in the US. The US was the 7th country to have such restrictions, but was not the first by about a week.

To this point, while somewhat typical of Trump to be dismissive, the response coming from the CDC and the White House seems to be quite reasonable. During the month of Febuary, the biggest concern was the possibility of a lack of Personal Protective Equipment, such as masks and glove and other such things, as China was then in a state of lockdown, and manufactures much of those goods. President Trump requested funds on Feb 5 to help secure such equipment, but it took over a month before the funding was authorized. During this time period, President Trump continued with a pattern seen during much of his Presidency. The official actions coming out of the White House were much the right thing, but he was extremely dismissive of it publicly. This may have contributed to the delay in funding, as so many people were dismissive, despite the White House knowing full well it had serious damage potential early in the month.

The bottom line is, 3 major issues plagued the US in the early days of COVID-19. The first was a lack of a good test, which I have not seen, but was primarily a CDC issue. The second was the lack of funding for personal protective gear. The last was related to the first, because tests could not be done quickly enough, the disease escaped in to the community. COVID-19 genuinely didn't seem as bad in the US as other countries in those days. In my opinion, except for these issues, it seems like it was relatively well managed.

As a preemptive action, many states began issuing restrictions in early March. Mid-March, the first formal guidance came out of the White House, restricting gatherings of more than 50 people Shortly thereafter, that number was decreased to 10. This was perhaps a week or so late, but was very much the right thing to do.

Another item of note is Operation Warp Speed, a greatly accelerated vaccine program. In my opinion, this is the single best thing that President Trump has done to combat COVID-19. This program works with private labs to help them work faster, including in many instances pre-ordering potential candidates even before Phase 3 trials had been complete. In the very early days, Bill Gates was talking about doing this, however, it seems he stepped aside after the US started to fund these efforts directly. It seems like Operation Warp Speed was in development at that time, but was not publicly annouced until the end of April.

As there is now a vaccine that is approaching the critical stage of Phase 3 trials compelte, let's look at what Operation Warp Speed really is. Fundementally it does 4 things. First, it directly funded several vaccine efforts. Secondly, it pre-ordered candidates to allow for manufacturing before the final approval was made. The same safety standards apply to the public, although the 3 phases of vaccine trials could be combined to some degree. Fundementally it is the same thing as Bill Gate's idea, fund multiple candidates production lines before the vaccine has been approved to speed up the process of getting it in to people's hands. It also helps facilitate the logistics of transporting the vaccine to states, and requires each state to have a plan to distribute it to the masses.

From May to the present date, I would say that by far President Trump's biggest problem has been a lack of following the guidelines that the CDC and White House are issuing. President Trump frequently refused to wear a mask, it wasn't until July 12, about 3 months after the CDC suggested wearing masks, before President Trump was photographed wearing a mask. He was ferquently dismissive of them. It is worth noting that for each rally he had on his re-election campaign, each atendee was provided a mask and encouraged to use them, although as Trump was so dismissive of them publicly, it seems that was not in fact followed.

So how do I grade Trump's response overall? He did a fair job at trying to restrict the entrance of COVID-19 in to the US in the early days. While he recognized the problems early on, he was unable to convince Congress to fund measures quickly, likely owing to his dismissal of the disease. Still, until the end of April, I think he did a fair job. After April, he was less involved in the day-to-day fight for COVID-19, not issuing further guidelines, trying to coordinate with states, and setting a bad example with his campaign rallies and lack of using a mask. Therefore, I rate his plan to fast-track a vaccine as good, his January-April performance as fair, and his May to current date as poor.

What does it mean to be a "Free" nation?

One of the things that I frequently see in online discussions is the concept of a "free" nation. But what exactly does that mean?...
