It Is Easy to Overreact to the Chinese Coronavirus

Recently, a new coronavirus has been causing many illnesses and deaths. The virus first became active in Wuhan, China, but it has already spread to the rest of China. Scattered cases have been identified around the rest of the world as well.

There are two important questions that are already being encountered:

  • How much of an attempt should be made to limit the spread of the new virus? For example, should businesses close to prevent the spread of the virus?
  • Should this disease be publicized as being far worse than flu viruses that circulate each year and cause many deaths among the elderly and people in poor health? The median age of those dying from the new coronavirus seems to be about 75.

Unfortunately, there aren’t easy answers. We can easily see the likely outcome of under reaction. More people might die of the disease. More people might find themselves out of work for a couple of weeks or more with the illness. We tend to be especially concerned about ourselves and our own relatives.

The thing that is harder to see is that reacting too vigorously can have a hugely detrimental impact on the world economy. The world economy depends on international trade and tourism. China plays a key role in the world economy. Quarantines of whole regions that last for weeks and months can have a very detrimental impact on the wages of people in the area and profits of local companies. Problems with debt can be expected to spike. The greater the reaction to the coronavirus, the more likely the world economy will be pushed toward recession and job loss.

The following are a few of my thoughts regarding possible overreaction:

[1] The Chinese coronavirus seems to be extremely contagious, even before a person who has been exposed shows any symptoms. The only way we can be certain to contain the virus seems to be through quarantines lasting up to 14 days.

China’s National Health Minister, Ma Xiaowei, has provided information that seems quite alarming. With the new virus, a person may become communicable shortly after he/she has been infected, but symptoms may not appear for up to 14 days. This allows the infected person to infect many others without realizing that he/she is a carrier for the disease.

Today, the United States and many other countries screen for the virus by checking passengers arriving on planes from affected areas for fevers. Given the information provided by China’s National Health Minister, this approach seems unlikely to be sufficient to catch all of the people who may eventually come down with the disease. If a country really wants to identify all the potential carriers of the disease, it appears that a 14-day quarantine for all travelers from infected areas may be needed.

Such a quarantine becomes administratively difficult to handle for the huge number of people who are likely to travel from China. Such a quarantine would make it impossible for pilots and other airline workers to make a living, for example. They would be spending too much of their time in quarantine to do the work needed to support themselves and their families.

A related concern is that person-to-person transmission is very easy with the Chinese coronavirus. We don’t know for certain how many people each infected individual infects, but one estimate is that each infected person transmits the disease to an average of 2.5 other people. With this transmission rate, the number of people having the disease can be expected to grow exponentially, perhaps for several months.

Based on these concerns, it seems to me that funds spent on trying to contain the coronavirus are likely to be largely wasted. The new Chinese virus will spread widely, regardless of attempts to contain it. At most, quarantines will slightly slow the transmission of the disease. At the same time, quarantines will be quite disruptive of commerce. They will tend to reduce both total wages and total output of goods and services of the area.

[2] Deaths from pathogens are part of the natural cycle. They help prune back the population of the old and weak.

We know that in ecosystems, one of the functions of naturally occurring fires is to clear out “deadwood,” to allow healthy new growth to occur. In fact, some types of seeds seem to require smoke for germination. When inadequate natural burning takes place, bushfires as seen in Australia and forest fires as seen in California become an increasing problem.

Deaths from pathogens seem to play a similar role in human economies. This is especially the case with pathogens that especially target the weak and old. Most flu viruses have this characteristic. Early reports of deaths from the coronavirus suggest that this same pattern of targeting the old and weak is occurring with this virus as well. As noted above, the median age of those dying from the new coronavirus seems to be about 75 years.

Since the 1940s, modern medicine has been able to develop antibiotics and vaccines to counteract the impact of many pathogens. This, of course, makes citizens happy, but it has the disadvantage of changing the population in a way that leaves the economy with a much higher percentage of elderly people and others in poor health. This higher level of elderly and medically needy people makes it easy for viruses and other pathogens to make their rounds, just as leaving deadwood on the forest floor makes it easier for fires to spread.

With this rising population of people who cannot support themselves, tax rates for the remaining citizens tend to become very high. Young workers may become discouraged because they do not have enough income remaining after paying taxes to raise their own families. In effect, they cannot support both their young families and the many old people.

Viewed from this unusual perspective, the operation of the Chinese coronavirus might even be considered a benefit to society as a whole. The world has overcome the impact of measles, typhoid, polio, and many other diseases. In some sense, it “needs” a new disease added to its portfolio, to replace the ones that have been mostly taken care of by modern medicine. In this way, pensions and other payments targeting the old and weak don’t become too great a burden on the young.

[3] If the Chinese coronavirus were simply allowed to run its course, without publicity that it was in any way unusual, somewhat less than 1% of the world’s population might be expected to die. 

To see what would happen if the Chinese coronavirus were to run its course, we might look at what happened with the Spanish Flu, back in 1918. At that time, doctors did not have a way of treating the virus and authorities downplayed concern for the disease. The US Center for Disease Control reports that 500 million people, or one-third of the world’s population, became infected. At least 50 million people (about 10% of those infected) died.

We don’t yet know with accuracy how many of those infected will die from the current virus. A recent estimate is that about 2.3% of those who are infected will die of the disease (based on 107 dying out of 4,600 infected). If we assume that the percentage of the population that will ultimately catch the new virus is 30%, then the share of the world’s population that would be expected to die would be about [(1/3) x 2.3% = 0.76%].

The UN estimates that the world’s population can be expected to grow by about 1.05% in 2020. If this is the case, the effect of the Chinese virus would be to sharply dampen the population increase for the year. Instead of population rising by 1.05%, it would rise by only 0.29% (= 1.05% – 0.76%), assuming all of the deaths associated with the Chinese coronavirus take place within a year. While this would be a change, it would be a fairly small, temporary change.

All of these deaths would be tragic for the families involved but, in a way, they would be less of a problem than the deaths that took place back in 1918. At that time, mortality was high for healthy 20- to 40-year olds, making the flu particularly disruptive for families. The total percentage of the population that died was also much higher, about 3% instead of 0.76%.

[4] A major danger of the virus seems to be one of overreaction.

Today’s world economy is fragile. China, like other countries, has a large amount of debt. Debt defaults related to poor profits of companies closing their operations for a time and workers losing income could easily skyrocket.

Closing down transportation from China would risk pushing the world economy into a very bad recession. In fact, simply having a very large number of people out sick from work would be expected to have an adverse impact on the economy. Spending a large amount of money on hospitalizations and face masks cannot compensate for the loss of productivity of the rest of the economy. Thus, the tendency would be toward recession in China, even if no action toward cutting off travel were taken.

China is a huge supplier of goods to the rest of the world. In fact, in 2016, it used more energy in producing industrial output than the United States, India, Russia and Japan combined.

Figure 1. Chart by the International Energy Agency showing total fuel consumed (TFC) by industry, for the top five fuel consuming nations of the world.

China’s economy has been growing very rapidly since 1990. Figure 2 shows this one way, in GDP comparisons using inflation-adjusted US dollars.

Figure 2. GDP of China and the United States, computed as percentages of World GDP. All amounts in 2010 US dollars, as provided by the World Bank.

Figure 3 is similar to Figure 2, except the growth comparison is made in “2011 Purchasing Power Parity International Dollars.” This adjustment is made because typically the currencies of less developed nations float far below the dollar, in terms of what the local currency will buy. The inflation-adjusted PPP comparison compares output on a basis that is expected to be more consistent with what the local currency will really purchase.

Figure 3. Ratios of the GDP of China and the United States to the World GDP. All amounts in 2011 Purchasing Power Parity International Dollars, as provided by the World Bank.

On this PPP basis, China’s GDP surpassed the US’s GDP in 2014. Figure 3 also shows that the United States has slipped from about 20% of the world’s GDP to about 15% on this basis.

We cannot simply cut off trade with China, regardless of how bad the situation is. China is too big and too important now. The rest of the world desperately needs goods and services produced in China, in spite of what is going wrong from an illness perspective. China plays too key a role in supply chains of many kinds for the country to be left out.

Even cutting off tourism becomes a problem. The share of China’s revenue from tourism amounted to 11% in 2018. While not all of this would drop off, even a dip would lead to lower employment in this part of its economy. Jet fuel use would drop as well.

[5] A particular problem today is low prices for many commodities, including oil and other fossil fuels. These prices are likely to fall further, if China’s economy falters further. 

We used to hear that the world would “run out of” oil and that oil prices would rise very high. In fact, if the people who were concerned about the issue had studied history, they would have figured out that a far more likely outcome would be “collapse.” In such a situation, prices of many commodities might fall too low. Revelation 18:11-13 provides a list of a number of commodities, including humans sold as slaves, for which prices dropped very low at the time of the collapse of ancient Babylon.

The problem is a different squeeze than a high-price squeeze. It is more of a growing wage disparity problem, with fewer and fewer of the world’s workers being able to afford the goods and services made by the world economy. This problem feeds back to commodity prices that fall too low for producers of many types. The problem is an affordability issue, rather than one of running out. I have written about this issue many times.

Prices of fossil fuels have been low for a very long time–essentially since late 2014. OPEC has cut back its oil production because of low oil prices. Several US natural gas producers have taken big write offs on natural gas investments. China’s coal production has remained below its 2013 level, because of low prices.

Figure 1. China energy production by fuel, based on 2019 BP Statistical Review of World Energy data. “Other Ren” stands for “Renewables other than hydroelectric.” This category includes wind, solar, and other miscellaneous types, such as sawdust burned for electricity.

If China finds it necessary to cut back on production of goods and services for any reason (excessive sickness within China, visitors aren’t traveling to China, tariffs, customers around the world aren’t buying cars), this reduction in output would be likely to further lower the prices of commodities. More producers would go bankrupt. Countries exporting products as diverse as oil, iron ore, copper and lithium might have economic difficulties.

Lower fossil fuel prices may lead to a cutback in their output, but it is doubtful that this cutback would be offset by an increase in the production of renewables. Falling fossil fuel prices would make the price comparison of renewables to fossil fuels look even worse than it does today. China has cut back on its subsidies for solar panels, and this has led to decreasing Chinese solar installations in both 2018 and 2019.

[6] The best approach might just be to let the Chinese coronavirus run its course. Authorities might also discourage stories about how awful the illness is.

Today, we seem to think that we can fix all problems. Unfortunately, this medical problem doesn’t seem to be fixable in the near-term. We should probably do as governments through the ages have done, which is not very much. We should not publicize the disease as being a whole lot worse than flu viruses in general, for example.

We should certainly look for inexpensive treatments for the disease. For example, there seems to be an effort to examine the possibility of using existing antiviral drugs as a treatment. It seems like an effort could be made to look into ways of treating the disease at home, perhaps using supplemental oxygen for a period. In time, perhaps a vaccine can be developed.

Individuals around the world should be encouraged to get themselves in as good health as possible, so that their own immune systems can fight off pathogens of all types, not just this particular virus. Common sense should be used in washing hands and in avoiding being with sick people. I doubt that it makes sense to encourage the use of masks, goggles and other protective devices.

We, as individuals, cannot live forever on this earth. We also cannot spend an unlimited percentage of GDP on health care: It becomes too high-cost for most citizens. At some point, we need to call a halt to the expectation that we can fix all problems. We live in a world with limited resources. We need to start lowering our expectations, if we don’t want to make our problems worse.

About Gail Tverberg

My name is Gail Tverberg. I am an actuary interested in finite world issues - oil depletion, natural gas depletion, water shortages, and climate change. Oil limits look very different from what most expect, with high prices leading to recession, and low prices leading to financial problems for oil producers and for oil exporting countries. We are really dealing with a physics problem that affects many parts of the economy at once, including wages and the financial system. I try to look at the overall problem.

    taxi driver dies from virus:

    “Taiwan reports first death from virus:
    The first death due to COVID-19 has been reported in Taiwan, its health minister said.
    The deceased was a taxi driver in his 60s and was hospitalised on February 3 due to shortness of breath, which led to a diagnosis of pneumonia. He died late on Saturday, Health and Welfare Minister Chen Shih-chung told a televised news conference.

    According to Chen, one of the man’s family members also contracted the virus. While the man had not travelled abroad, he had previously transported people from China, Hong Kong and Macau.”

    “Taiwan reported the first death from coronavirus on Sunday, and added two more confirmed cases, bringing the total to 20…”

    so a 10% increase in one day…

    these numbers seem small, but…

  2. Covidinamonthorayearoradecade says:


    “All passengers who have already disembarked from a cruise ship docked in Cambodia are now being tracked, after an American passenger tested positive, according to a Reuters report.

    Holland America Line said it is working with governments and health authorities to track the other 1,454 passengers, who had been given the go-ahead to travel by Cambodian authorities after health checks were done. Many have left the country as of Sunday, the report said. The ship has 802 crew.”

    “Many have left the country…”

    good to go “by Cambodian authorities after health checks were done”…

    whew… that’s okay then… they did “health checks”…

    wouldn’t want the virus to spread further…

    • Covidinamonthorayearoradecade says:

      An American woman who disembarked from a cruise ship in Cambodia last week has tested positive twice for the coronavirus since flying on to Malaysia, officials in that country said on Sunday.

      Cambodia allowed the ship, the Westerdam, to dock after five other ports turned it away over concerns about the coronavirus.

      Officials said more than 140 passengers from the ship had flown from Cambodia to Kuala Lumpur, Malaysia’s capital. All but the American woman and her husband had been allowed to continue to their destinations, including airports in the United States, the Netherlands and Australia.

      The woman, who is 83, and her husband, who is 85 and also an American citizen, were both hospitalized and placed in isolation. The husband tested negative for the virus, but he has pneumonia, which is often a sign of the virus.

      Dr. Eyal Leshem, director of the Center for Travel Medicine and Tropical Diseases at the Sheba Medical Center in Israel, called the disclosures “extremely concerning” and said, “We may end up with three or four countries with sustained transmission of the virus.”
      The Westerdam, carrying 2,257 passengers and crew, departed from Hong Kong on Feb. 1 and was at sea for nearly 14 days.

    • The cruising line company (+embassies & bankers) clearly pushed and bribed the easiest target around, Cambodian govs to open the proverbial gates. Giving what we have learned meantime about the ship in Japan this is outrageous, yet reflective of the state of the world and or human nature.

      • Xabier says:

        The dispersal of those passengers after probably no more than the ineffective temperature test is a scandal.

        Even worse, perhaps, the persistent acceptance of unrestricted Chinese flights by the Ethiopians, serving as the entry point to Africa.

        I wouldn’t care to be a Chinese worker in Africa once they are seen as the source of a fatal infection – do the Chinese have troops there one wonders?

        • Well. it could be “all of the above” – keeping the Chinese investments in Africa humming, taking their African biz partners (and workforce) es expendable, as well as now most likely knowing the virus has got racial bias for Chinese/Asians anyway..

        • Country Joe says:

          “McAuliffe argues that our dread of contamination is an evolved defense against parasites. The horror and revulsion we are programed to feel when we come in contact with people who appear diseased or dirty helped pave the way for civilization, but may also be the basis for major divisions in societies that persist to this day.”

          THIS IS YOUR BRAIN ON PARASITES ( is a somewhat light hearted title for a well-researched book on parasitic behavioral influence and on our increased conservatism and prejudice to avoid contact when contagion is perceived.

          From the information in these studies it would appear that the current publicity around COVID-19 should add strength to our current political trajectory.

  3. Always kind of funny when topics debated years on the internet finally appear on the msm as self evident truths.. Like on this Gulfies msm “.. destabilization period (almost prewar)..”

    For the gist of it, you can rewind for the last ~third..

  4. Harry McGibbs says:

    “The novel coronavirus is spreading silently and invisibly through its human carriers, inflicting fear and sickness. Likewise, malaise can spread through the “carriers” of the global economy: the supply chains that link myriad manufacturing and service-sector firms around the world.

    “These supply chains are the circulatory or nervous systems of the global economy and, like their equivalents in the human body, receive little or no attention until things go wrong. Once they do – which is increasingly often – our extreme vulnerability to these hidden links is exposed.”

  5. Harry McGibbs says:

    “”The sharp drop in output after October’s sales tax hike supports our view that Japan’s economy will shrink this year,” Capital Economics wrote in a note after the data was published. “But after today’s release, our forecast of a 0.2% drop in GDP in 2020 looks optimistic.”

    “Other economists warned the longer the virus continues to infect people, the more the risks to Japan’s economy will grow.”

  6. Harry McGibbs says:

    “Prime Minister Boris Johnson has been warned that he will face a tough battle with the European Union in his efforts to secure a trade deal in the aftermath of Brexit.

    “France’s foreign minister Jean-Yves le Drian gave the prediction during the Munich Security Conference, as both sides prepare to begin negotiations…

    “The UK’s chief negotiator David Frost is set to make it clear that Mr Johnson will walk away from talks with the EU, unless it drops what he calls its “ridiculous and unreasonable” demands.”

    • Harry McGibbs says:

      “Pantheon Macro economist Claus Vistesen said the fall of the Eurozone may get worse due to coronavirus spreading… He warned “Germany is on verge of recession again and these numbers are all from before coronavirus”.

      “But Berlin is not alone in dragging the Eurozone down into an economic crisis. The French economy has also ground to a halt, largely due to protests triggered by French President Emmanuel Macron’s crippling pension reforms.”

    • Robert Firth says:

      I doubt it. The Eurozone is in crisis, because the departure of the UK has left an unfillable hole in its budget. The oligarchs in Brussels cannot reduce their exactions, because their sole power base is an enormous army of grossly overpaid bureaucrats busily interfering in anything and everything. But they cannot extort more from the member states, because the latter are already rebelling: the contributors (both of them) cannot pay more, and the spongers (the rest of them) are kept in the game only by open ended subsidies and bribes.

      So create an external enemy to hold the ranks together. Just as France did to the Templars, and Germany to the Jews. It won’t work, because the EU has no means of projecting power against a sovereign state. The pitiful excuse for an EU “army ” was practically run out of Paris when it dared to show its armoured vehicles, and anyway was trained only for internal oppression, not external defence. The EU more and more seems to resemble the Bourbons of France or the Romanovs of Russia, holding on to the illusion of power even as the reality drains away into history.

      • So it sounds like the Eurozone needs to cut back on their staff and the services they provide. Maybe they need to back off on some of the requirements that they are trying to enforce, such as lower CO2 emissions from cars.

  7. Harry McGibbs says:

    “Global defense spending saw its biggest jump in a decade in 2019, driven by the U.S. and China as rivalries and conflicts stoke military investment.

    “The International Institute for Strategic Studies said the 4% rise, compared to a year earlier, was fueled by competition between major powers, new military technologies and rumbling warfare from Ukraine to Libya.”

    • Both the U.S. and China increased spending by 6.6 percent, the report said, to $684.6 billion and $181.1 billion respectively.

      Lots of employment for young people, I expect. Keeps people’s concerns off of general economic problems.

    • The Orange Jesus clan will collect commission from this one as well, the only question is how much? Say 4% hike out of 684B is 27B, now if you strip it out of inflation, dividends (for fellow bankers and manufs), and kickbacks for low level staffers in various offices, one can reasonably assume Donny’s family is in at at least for $1-5B.

      That’s why and how you climb the ladder from “impoverished almost billionaire class” to proper lesser billionaire rank status.. well and there are at least ~2-3layers above that..

  8. Yoshua says:

    “Cruise ship stats:
    Total on board (initially): 3,700
    Positive for coronavirus: 454 (12%)
    Tested so far: 1,723”

    • Most of the number of tests quantities I have seen do not distinguish how many times a particular person has been tested. Thus, I expect that the 1,723 amount is the “number of tests given,” not the number of different people on the cruise ship tested. Some people could be suspected of having the virus, but test negative over and over, for example. Perhaps 1,400 different people were tested, out of the 3,700.

      • Yoshua says:

        I don’t know. But if it’s one test per person then then infection rate is 25% so far.

        • Yoshua says:

          I came down with the flu 15 days ago and still have symptoms. This flu is no killer though.

          I asked my Chinese friend if she has received any packages, letters or postcards from China lately.

          She smiled and said: Don’t worry!

          She has no symptoms.

          • Covidinamonthorayearoradecade says:

            “The source also said the virus has “outsmarted all of us,” as it can hide symptoms for up to 24 days.”

          • Chrome Mags says:

            “I came down with the flu 15 days ago and still have symptoms.”

            Something my wife and I noticed is when we lived in a more congested area, we got colds and flus much more often. Out in the country where there are about 10,000 people but scattered about, we rarely get sick now. So that’s likely a big factor on a cruise ship for quicker transmissibility.

    • Chrome Mags says:

      Of those tested 454 out of 1723, is actually 26.35%, quite higher than the 12% of 3700. We better hope the % getting this globally, should this become a pandemic in huge numbers, that 26.35% don’t get it, because then it would be a full blown disaster.

      • It really depends on how sick these people get from the flu.

        I plan to put up a post later today that will talk a little about what seem to be differences in genetic groups in how sick they get. It may be that people of European ancestry don’t get as sick with this illness as their Chinese counterparts.

  9. Yoshua says:

    We have something in common with the Flatearthers. They too live in a finite world. They have the rim. We have the Seneca cliff.

  10. kevin moore says:

    I think the coronavirus probably originated at the Wuhan Virology lab reportedly situated 300 yards from the wet market u fee scrutiny. Just too much of a coincidence.

    • kevin moore says:

      “…wet market under scrutiny.”

      • Chrome Mags says:

        Now I’m going to post this first then a 2nd post with a link to a video. It was deleted yesterday but maybe today the link will post, but first let posters know what the video was saying; that Chinese scientists are implicating the research lab as they call it, that is only 280 meters from the wet market implicated in the spread of the Corona Virus. That lab they say in the video has 600 infected bats.

        In China it’s likely these scientists would only disclose such information if allowed by the govt. because of possible harsh penalties if they just went rogue and announced it. My thought on this is the govt. instructed them to leak this suggestion as a way of easing into the fact it came from that lab. You be the judge if I can get the video posted in the next posting.

        • Chrome Mags says:

          Ok, so it’s awaiting moderation and may not go live. I understand that video’s take up a lot of compute space, so no worries if that’s why it’s not being posted.

          But you can do a search on YouTube and find it – put in: Chinese scientists says COVID-19/coronavirus could have originated from government …

          • kevin moore says:

            The Wuhan Virus Lab became the first and is still the only lab in all of China with top level bio safety certification (level 4) in 2015. What are the chances that in all of China the coranavirus would originate so close to this location? Will China be liable for costs and suffering resulting from this disease?

            • Are you kidding? Or do you mean like the precedent as WWII polish and other pilots flying (and dying) for RAF had to pay up her majesty afterwards for all their gear incl. shoe laces.. ?
