China: Oct 1st, 2020, celebrations of the national day. From this and other pictures, it is clear that the Chinese are not too much worried about getting close together, even without wearing face masks (source)
The text below is the translation of a post I published in Italian on the Facebook site "Pills of Optimism" on Oct 26th. There are still many things we have to understand about how China managed to control the COVID-19 epidemic. But one thing is certain: it was controlled and it is still under control.
In China, stopping the infection required little more than a regional lockdown that interested a small fraction of the Chinese territory: the Hubei province, about 4% of the total population of China. Coupled with aggressive tracking and isolating, it was enough to get rid of the virus. There have been no COVID-related deaths in China since March 2020. The Chinese economic machine is in motion, people move, travel, shop, walk around, often without face masks. In short, life is normal. And it has been normal during the past six months, at least.
In comparison, the epidemic in the West has been so badly mismanaged that one feels like crying of rage. A threat that never was overwhelming was magnified to the point that it risks destroying the very fabric of the Western economic machine. How could it happen?
Within some limits, the collapse of the Western economy was unavoidable for reasons related to the decline of the availability of natural resources. But that it happened so fast is bewildering. So surprising that some people maintain that it was a conspiracy against the West concocted by China or even a plot by the evil Western elite to get rid of their useless Untermenschen.
Maybe, but it is more likely that, simply, the West lost control of its governance system that went on by itself like an individual immune system that suddenly attacks its host.
What can we learn from this story? Mainly, that we can't afford to be dominated by the waves of self-reinforcing hysteria that go through the media and the social networks. How can we manage that? Well, good question. Imitating China would mean giving most of the power to the Communist party, and that doesn't sound so viable, nowadays, in the West. But, seriously, we must rethink our governance system, otherwise the next serious crisis will truly destroy us. (supposing that we survive the current one)

💊💊💊 From the data arriving from China, it seems that things are going very well with the COVID epidemic. In China, as well as in all of East Asia, mortality was much lower than in Europe and no deaths have been reported since March. There are still many things to clarify in this story, but China can teach us that it is possible to stop the spread of the virus without harming the economy. 💊💊💊
Do you remember when, in January, the Chinese (or those who looked like Chinese) were insulted in the street in Italy by people who believed they were spreading the plague? Things have changed quite a bit and today it is the Chinese who believe that we Italians are the plague spreaders.
In China, there have been no deaths from COVID-19 since about mid-March. As for positive cases, there have been only occasional outbreaks of a few dozen cases, almost all of them imported (2). The Chinese economy has restarted to move and is now running at full capacity.
From what we can read in the international media and from what colleagues who live and work in China tell me, the country is completely open. All commercial and industrial activities are in operation. The shops and restaurants are open and there are no restrictions on internal travel. Wearing face masks is optional and many people don't wear them. From the photos that come from China, we see that people do not pay much attention to the gatherings of people without masks. (below, celebrations of the National Day in Wuhan, Oct 1st)
Of course, the authorities are still on their guard and they intervene as soon as small outbreaks emerge. For example, the authorities of the city of Qingdao recently discovered an outbreak that, according to the international media, may be related to a batch of imported frozen cod on which someone would have observed viruses still whole. True or not, hard to say, but in any case, the local government is committed to testing all the 9 million inhabitants of the city! (3).
But, overall, it is clear that in China and elsewhere in Asia the epidemic is under control without the need for a lockdown or other harsh measures of containment. Not only does the epidemic seem to have disappeared in China. It also created very little damage, at least according to the government data. The total number of victims is reported to have been about 4,600 out of almost one and a half billion people. That means 3 deaths per million against about 600 in Italy and other Western countries. Even if we only consider the European regions where the virus has hit the hardest, we find that the province of Hubei still did better. (4)
How is such a thing possible? We often read on social media and on the media that the Chinese cheated us and that they are continuing to cheat us. Since China is a dictatorship, it is said, it follows that everything the Chinese government tells us is false by definition - including the fact that the epidemic is gone. Could it be that people are still dying of the COVID in China, but the government doesn't tell us?
Governments are not known to be reliable sources of information. We saw in a previous post how at least one European country, Belarus, may have partially falsified the data on the epidemic (5). As for China, there are previous cases of falsified data. For example, an analysis of fisheries data arriving from China in the 1990s indicated obvious falsifications to hide the depletion of stocks (6), (7)). But an epidemic is a far more serious and more extensive business than a fraud in a specific commercial sector. It would also be very difficult for the Chinese government to hide it if there was one in progress.
So, if we want to believe that the Chinese are telling us lies about the epidemic we must bring some evidence on this. Remaining with the example of the fishery data, one of the reasons that led to mistrust the validity of the Chinese data were the anomalies that were noticed when comparing with data from other similar regions. Can we find any such anomaly for the pandemic? Apparently not: the data on the spread of COVID-19 in China are comparable to data from other neighboring Asian countries which, in general, have had minimal or no mortality.
For example, Taiwan did even better than mainland China with a total of 7 deaths per 23 million inhabitants (less than one death per million). Other countries did a little worse but still remained at very low mortality levels. Singapore reports 5 deaths per million, Hong Kong 13. Neighboring Japan also suffered only 13 deaths per million. Then, both Mongolia and Macao even report zero deaths. Sure, one might say that Mongolia doesn't count because it's a country of camel drivers living in tents in the middle of the desert. But, of course, that's not the case. The capital of Mongolia, Ulan Bator, is a metropolis with over one million inhabitants. Macau, then, is a city of 700,000 inhabitants with a very high population density, perhaps the highest in the world. And the epidemic went through both Ulan Bator and Macau without leaving a single victim! It is hardly credible that all these governments have agreed to hide an ongoing epidemic from the rest of the world.
But why are things so much better in Asia than here? Did the Chinese have used particularly effective containment measures? In some ways, this year's Chinese lockdown may have been more drastic than the Western one, but it didn't last longer than in Europe. It is not even possible to say that it was more timely if, as the Chinese themselves say, the virus was already circulating in December. The lockdown was established in Wuhan only on January 23 and a few days later for the entire province of Hubei.
In terms of "social distancing," we all know that in Asia there is a tendency to avoid physical contact between people. But it is also true that if you have ever taken the subway in an eastern city (for example in Tokyo (8)) you will have a very specific idea of the meaning of the expression "squeezed like sardines". If you never had this experience, take a look at this link to an impressive video of the Beijing metro (9). Eastern metropolises are extremely crowded and, under certain conditions, it is simply impossible to avoid physical contact.
Could it be then that the trick was in contact tracking and isolating? From what we can read, it seems that Asian countries have been very aggressive in tracking and isolating people who have been in contact with people affected by the virus (10). This is an interesting explanation, but tracking and isolating was done in Europe, too. Maybe we haven't done it well enough? It is possible, but we have no quantitative comparisons that can tell us if this is the only explanation for the whole story.
There is also another possible interpretation that has nothing to do with what governments have done or not done. It may be that the Chinese have been exposed to the virus for longer than we in the West and therefore approached herd immunity first. You probably heard of Li Wenliang, the Chinese doctor who first noticed cases of abnormal pneumonia in December and who later died of contracting the infection himself. Initially, he was not believed, but today he is considered a hero in China.
Li had begun to sound the alarm towards the end of December 2019, but nothing prevents us from thinking that the virus had already existed in China for some time, perhaps even in slightly different forms from the one that then hit Europe. It was just that those affected were diagnosed as normal cases of pneumonia.
Is it possible that the Chinese population had been exposed to the virus long before the declaration of the emergency? There is a fact that could give us a strong indication in this regard: excess mortality. If the epidemic already existed in November-December 2019, or even earlier, we should see an abnormally high mortality in China, compared to the average for that period.
Good idea, but with a problem: nowhere on the Web we can find data on the additional mortality in China during the COVID pandemic. Note that this does not mean that the Chinese government is hiding anything from us. Hardly any government in the world disseminates these data in an easily accessible form. Europe is an exception with a database on excess mortality called "Euromomo" managed by a network headed by WHO, but there is no such thing for East Asia. So, for the moment, the idea of an early start of the epidemic in China remains a hypothesis.
There are other factors we could look at but this virus has accustomed us to the fact that predictions and interpretations always turn out to be wrong. Even in a recent article in Nature (11), the authors frankly said that "we are not yet able to provide a generalized explanation for the observed quantitative mortality differences between countries". Thus, we must content ourselves with saying that the epidemic has done much less damage in Asia than it did for us for some reason that, at the moment, we cannot identify with certainty.
But let's stick with what we know, which is that at the moment things are going very well in China and in the whole East Asia, just while the West is experiencing a "second wave." At least, we can conclude that we are not facing an invincible enemy. It is possible to beat the Sars-Cov-2 without necessarily having to destroy the economy with prolonged and generalized lockdowns. Of course, we are in a very difficult moment here, in Europe, but there is no reason to think that we will have to continue living in terror for centuries to come.
