We cannot exclude the hypothesis that coronavirus is an American made virus that has gone out of control and a part of it went back to the US.
The virus passes over states not involved in major issues of world politics, and is spreading on territories where the global stakeholders’ interests collide. Of course, other countries are affected, but the virus does not present any danger for them.
The virus has selected China, Iran, Italy and Spain as targets. Stuck between Spain and Italy is France. Their neighbours are affected less, if affected at all. In Mongolia on 23 March there was only one case, though the country is populated by as many Chinese as Mongolians and the borders between China and Mongolia have remained open.
An baseless conspiracy theory with no evidence given. For accurate and up-to-date data on the spread of COVID-19, see the sites of the European Centre for Disease Control or the World Health Organisation.
