Are East Asians resistant to COVID19? Is this virus for the first time in humans?

One can observe that the rate of spread of COVID19 virus in East Asian countries is much lower than the rest of the world, especially the European and US. One might suspect that this is not coincident. We know that there is very low genetic differentiation that ranges only FST (fixation index) between 0.002-0.009 among the East Asians (the Han (Chinese), Korean, Japanese) while the smallest differentiation between European and East Asian people scores FST= 0.0838 goes as high as 0.1059 (Wang et al. 2018). i.e., the genetic variation between the East Asians and Europeans is up to over 50 times the variation among the East Asian Major groups (Han (Chinese), Korean, Japanese). The low rate of spread of COVID 19 in east Asian countries, including where the disease started, perhaps is related to the genetic makeup of the people in these countries apart from the mitigation effort. Yet, the unprecedented efforts by the Chinese to bring down the virus after 80,000 cases should not be overlooked. Likewise, I acknowledge the deployment of advanced and intensive actions by Japanese and Korean to contain the virus. My view here is to bring other possibilities to attention based on what I can observe from the trend of data across regions.

Among the Europeans, we see the low death rate in Germany even though the spread is still nearly the same as the other severely hurt ones such as Italy and Spain. This somehow seems connected to the more advanced and well-structured system of Germany, not only the health care system but also many more, including the tradition of Germans exceptionally complying with rules and regulations.  The spread of the disease in North America, particularly in US, looks like what we see in European hot spot nations.  When it comes to genetics, once again, the vast majority of US citizens are of European origin.  Canada is way at a lower rate than its immediate neighbor and with also uncontrolled high population flow between the two.  Interestingly, the British Colombia province of Canada, where a large number of East Asian population in Canada lives, the virus seems spreading very slow relatively compared to the Quebec and Ontario provinces. However, BC was the province with a large number of cases when the virus entered the country.

Here is just to alert people working on this virus for one of the possibilities. East Asians might be inherently resistant to this disease. They might also acquire immunity in some unrecorded infection by the virus in the past. If the virus exists in the region, be it in batts or other animals, people might be exposed to this virus somewhere in the past, and for some reason, the virus might disappear. i.e., the current infection may not be for the first time in a human. Hence, individuals with inherited-acquired immunity from their ancestress might exist in large numbers in those regions (East Asia). There were also some unverified reports claiming Africans more resistant than Chinese. May be true.  Genetically, Africans are more deviant than European from the Chinese and/or East Asians.  But Africans and East Asians can have a similar incidence of the disease in a long history.  Or maybe due to homeoplastic evolutionary incidence.

I am sorry for my too much speculation. But it might be worthy sometimes to think of all the possibilities.

May almighty God have mercy on us and the entire world! Amen!

Thank you!

  1. Presently, the USA is the epicenter of the pandemic. To the north of that country is Canada, to the south, Mexico. By way of numbers – for both infections and deaths, Canada compares favorably with S. Korea; and Mexico with India. What is it that Canada has in common with S. Korea, and Mexico with India?

  2. Nice and well written article. It is an excellent conversational piece. There are a lot of articles out there written by many scholars where many of them are in agreement about COVID-19 and many others debunking each other. But there is one very obvious fact. The virus is new and nothing like any other contagious viruses. There are stark projections out there. Some experts are forecasting a death toll to more than 200,000 here in the USA alone between now and June with the spike happening in the next two weeks. That is if we ignore the mitigating steps we as common citizens should observe strictly as our experts advised. So dear compatriot!! Let’s hanker down and obey the do’s and don’ts as outlined in the President’s handout. This is a joke. This is not funny and this virus is not to fool around with. You should protect yourself so you will not infect the most vulnerable, the elderly and those with underlining health issues. We had come together on the hills and ravines of Adwa 124 years ago and beaten a bully who came there to call us all but we beat the living daylight out him until swore by his mama. We are faced this time by a new bully and we can beat him also. Let’s unite behind our leaders here and join the bitter fight. Let’s couple the do’s and don’ts with our daily prayers. Let’s throw ourselves at the feet of The Almighty Our Creator and beg for his blessings and forgiveness!!! This shall pass!!!!!
