Here are the main takeaways from the above entitled article:
"East Asians, Japanese, and Han Chinese are the most likely people to become severely sick by the coronavirus with a chance of more than 90% when exposed. Europeans only rank in the 50%, Africans in the 60% range, and considered low to medium. It also makes a difference if one is a smoker or non-smoker."

"The novel coronavirus (2019-nCov) was identified in Wuhan, Hubei Province, China in December of 2019.
This new coronavirus has resulted in thousands of cases of lethal disease in China, with additional patients being identified in a rapidly growing number internationally.
2019-nCov was reported to share the same receptor, Angiotensin-converting enzyme 2 (ACE2), with SARS-Cov.
Here based on the public database and the state-of-the-art single-cell RNA-Seq technique, the ACE2 RNA expression profile in the normal human lungs. The result indicates that the ACE2 virus receptor expression is concentrated in a small population of type II alveolar cells (AT2).
Surprisingly, studies found that this population of ACE2-expressing AT2 also highly expressed many other genes that positively regulating viral reproduction and transmission.
A comparison between eight individual samples demonstrated that the Asian male one has an extremely large number of ACE2-expressing cells in the lung. This is based on an unfinished study by Yu Zhao, Zixian Zhao, Yujia Wang, Yueqing Zhou, Yu Ma, Wei Zuo and published by Bio Rxiv :
A second study investigates how and why the virus will enter the human body, by Michael Letko, Vincent Munster
Apparently the coronavirus enters a human body through some connection with something called the ACE2 receptor. East Asians and men have more than say white Europeans and women. Being a white woman seems to be the way to have much lesser risk.
According to this study and based on the assumption in this study and in regards to the receptor, Angiotensin-converting enzyme 2, human populations where samples were available were categorized by risk in obtaining a dangerous version of the virus. Most ill may not feel more than a common cold, for others Coronavirus can be fatal."

Abstract
Angiotensin converting enzyme (ACE) gene polymorphism insertion (I) or deletion (D) has been widely studied in different populations, and linked to various functional effects and associated with common diseases. The purpose of the present study was to investigate the relationship between the ACE I/D frequency in different populations and geographic location.
