Abstract:The United States was the hardest hit area by the 1918 bet365 casino bonus。The national policy of “War Priority”、Unprecedented military training and worldwide military mobilization and fighting have created conditions for the widespread spread of the epidemic，At the same time, it also seriously weakened the United States’ epidemic prevention capabilities。The unprecedented epidemic has plunged American society into extreme panic，Having spawned various “geographical traceability” of epidemics，Some media have turned "flu tracing" that should be a scientific category into a "flu stigma" with geopolitical overtones，Theories such as “Spanish Flu”, “Russian Flu”, “German Poison” and “Chinese Plague” have appeared one after another。The unreasonable "geographical origin" of the pandemic was criticized by knowledgeable people in the American medical community at the time、Even questioned by Chinese medical experts。After the epidemic is over，Tracing the origin of the pandemic has become a professional issue in the field of pure medical science，Finding the real pathogen causing the epidemic has become the primary issue。Scientists from the United States and other countries have successively discovered the 1918 influenza virus and completed genetic sequencing，Making epoch-making progress in discovering the pathogen of the 1918 influenza，The importance of tracing the place of origin has taken a backseat。Although the geographical origin of the 1918 bet365 casino bonus cannot yet be determined，But the development of medical science is enough to deny the absurd "geographical origins" during the 1918 bet365 casino bonus in the United States。Historically speaking，During the 1918 bet365 casino bonus，The rash remarks of some media people hinder scientific exploration of the origin and spread of the epidemic，It has undermined normal international cooperation and international relations，worth pondering。
