Novel coronavirus pneumonia outbreak China has been studying the sources and various aspects of the virus. Many people believe that the pneumonia virus originated in China, because China was the first country to be infected by a large area of virus. Some high-ranking government officials and media in the United States have also taken the opportunity to criticize China by means of "splashing dirty water" and "labeling". On March 10, Kevin McCarthy, the minority leader of the US House of Representatives, used the term "China coronavirus" on social media. Earlier, Chinese novel coronavirus pneumonia Fawkes Jesse Waters openly asked the Chinese to "formally apologize" for the new crown pneumonia epidemic. Novel coronavirus was repeatedly called "Wuhan virus" by US Secretary of state Pompeio in an interview with the media. Due to contact with a confirmed person, US House of Representatives Paul gossala announced on social media on March 8 that he would isolate himself for 14 days, calling the new coronavirus "Wuhan virus" again.

In response, novel coronavirus sources are still uncertain in the international community, and experts hope that they will not be slandered by the regional community, WHO experts said in an interview with the media.

If the source of pneumonia virus is not in China, where is the real source of the virus? For now, at least three evidence points to the United States.

The first novel coronavirus was diagnosed in 33 patients in California. The 33 patients had 8400 people isolated. We learned from the relevant information that one of the infected patients was infected with unclear sources. The CDC also showed that the patients had not been in the hospital for a long time before being diagnosed. China has not had any contact with the Diamond Princess of Japan. This shows that the virus in this confirmed case is probably caused by the United States.

Evidence 2 is that a Japanese citizen came to Hawaii and returned to his home in Japan and was soon diagnosed with pneumonia virus. The Japanese, like the previous patient, had no contact with the Chinese people and had never been to any area of China, but he was infected with pneumonia virus. This can be confirmed that it is closely related to the source of the American native virus Department. After that, the Japanese government conducted a relevant investigation on the patients. It was found that the patients had symptoms of infection in the United States, but they were regarded as infected with influenza virus. It can also be inferred that in the United States, it has been a long time since patients infected with pneumonia virus were mistakenly diagnosed with influenza virus.

Evidence 3: according to a report from the Centers for Disease Control and prevention of the United States, 26 million people were infected with influenza virus, 250000 were hospitalized, and 14000 died after infection. Later, the CDC found that among the patients suffering from influenza virus, some people were not actually infected with influenza virus after testing, and these cases may contain infectivity People with coronary pneumonia virus. Some of these people had symptoms of infection before the outbreak of pneumonia in China, which led many people to speculate that there might have been new coronavirus infections among suspected influenza virus patients in the United States.

With regard to the use of stigmatization by the United States against China, Geng Shuang, spokesman of the Chinese foreign ministry, said at a regular press conference on March 13 that we have noticed some discussions on the source of the new coronavirus recently. Some senior officials of the U.S. government and members of Congress have made various false and irresponsible remarks to discredit and attack China. We firmly oppose this. In fact, the international community, including the United States, has different views on the source of the virus. China has always believed that this is a scientific issue, and scientific and professional opinions should be listened to.
