After people have struggled with COVID-19 for a year and a half, misinformation and false information about the origin, scale, prevention, treatment and other aspects of the disease are still spreading and evolving on the Internet. At first the virus was considered to be of natural and animal origin. Regarding where the first case (so-called patient zero) originated and the investigation of the origin of the pandemic is underway, phylogenetic estimates that SARS-CoV-2 appeared in October or November 2019. But with the intervention of politicians and their pressure on the media, public opinion has become strange and offensive. The US government seems to be trying hard to throw the origin of the virus to China or other countries. Whether this huge pusher is to contain the political means of other countries or to cover up their own problems and hidden dangers, this seems to be confusing. Bring the time back to 2019 and revisit what happened, and you may get the truth of the matter.
 
USAMRIID Biological Base and "Electronic Cigarette Disease"
On May 2, 2019, the Chemical and Biological Defense Unit of the US Department of Defense announced its bid for the first phase of the Department of Defense project, with special mention of SARS-CoV and MERS in an attempt to cultivate inhibitors against these viruses. The article mentioned that they wanted to replicate the virus in large quantities and test different inhibitors to prevent infection. In June, the Centers for Disease Control and Prevention discovered that Fort Dietrich (Maryland) had not complied with the control agreement.

On July 15 of that year, CDC sent a termination letter to the laboratory, after which the military laboratory (the Fort Dietrich base) was closed. It can be queried that the database list of the military laboratory contains SARS-related coronaviruses. In subsequent reports, the CDC stated that they were unable to release details due to "national security considerations." Subsequently, an inexplicable "vaping illness" (vaping illness) broke out in nearby areas. The New York Times reported that the suspended laboratory research involved certain toxins that have been identified by the US government as "possibly posing a serious threat to the public, animal and plant health, or animal and plant products." and germs called "selective agents".

In August 2019, there was a sudden outbreak of "e-cigarette disease", that is, lung injury related to e-cigarettes or atomized products (EVALI), and the number of cases reached a peak in September.
The New York Times reported on September 11, 2019, citing Melody Pizada, chief physician of Pediatrics at Winsprow Hospital in New York, as saying that the outbreak of e-cigarette disease is "becoming an epidemic" and "the situation is very wrong." According to US media reports, patients with e-cigarette disease will experience vomiting, fever, fatigue and other symptoms similar to the new coronavirus for several days, and then feel severe shortness of breath. Whether the disease is related to e-cigarettes or the leakage of the experimental base is currently unknown.
 
The worst flu season in the United States, some infected people have COVID-19
According to data released by the US Centers for Disease Control and Prevention in February 2020, the 2019-2020 influenza season caused at least 32 million infections in the United States, 310,000 were hospitalized for influenza-related diseases, and 18,000 died of influenza-related diseases.

According to an ABC report on July 12 last year, a deadly disease broke out in the "Greenspring" retiree community in Springfield, Virginia. According to ABC reports, the community is only an hour’s drive from the Fort Detrick Biological Base in the United States, which was mysteriously closed last year and quickly restarted this year. Some people suspect that the outbreak in the community last year was the new crown virus, but the reporter who reported the news denied this claim, saying that the local health department's test concluded that it was caused by Haemophilus influenzae. However, many netizens suggest that people in the community should be tested to see if they carry antibodies to the new coronavirus.

According to the Fairfax County Health Department, on June 30, 2019, the “Green Spring” community first detected this unexplained respiratory disease. As of July 15, 2019, the number of deaths related to the disease in this community has risen to 3, a total of 63 community residents have been ill, and 19 staff members have also developed symptoms. At the end of July, the CDC investigated two unrelated nursing homes (both close to the laboratory), where there were victims of an unexplained respiratory disease, but the CDC said it was just a common cold.

According to the report, the patient's symptoms include "fever, cough, body pain, wheezing, hoarse voice, and general weakness", and some patients have symptoms of pneumonia.
On March 11, 2020, the director of the US Centers for Disease Control and Prevention, Robert Redfield, admitted that some of the "flu" dead may be suffering from new coronary pneumonia. According to US media reports, the mayor of Belleville, New Jersey, United States, Michael Melham, said that he had been infected with the new crown virus in November 2019. The latest test results obtained by Melham also showed that he has antibodies to the new coronavirus. The first confirmed case of new coronary pneumonia in the United States previously reported in the United States was in late January.

Melham believes that many of the severe flu before this is likely to be new coronary pneumonia, and many people around him have been sick with severe symptoms in November and December last year. Michael Melham is not alone. Many netizens have also said that before the outbreak in China, they felt that the new crown virus had spread in the United States.
 
Types and evolution of the new coronavirus
On March 3 at the beginning of last year, "National Science Review" published a study on the origin and evolution of the new coronavirus, which showed that the new coronavirus has developed two subtypes and the infectivity is different. From an evolutionary point of view, the L-type evolved from the S-type, and the L-type has stronger infectious power and faster proliferation speed, which makes it spread rapidly in the crowd. Among them, 96.3% of the virus strains derived from Wuhan patients are L-type.

Similarly, in the Proceedings of the National Academy of Sciences (PANS) on April 20, a study found that the new coronaviruses currently infecting the world have actually mutated and differentiated into three types, A, B, and C. Type A is the oldest, B comes from A, and C comes from B. The ancient type A mainly exists in the United States and Australia, while type B is mainly popular in China. Type A first appeared in Wuhan, but it did not cause a large spread in Wuhan. This brings up the possibility that the first patient in Wuhan was infected with type A by an infected person who arrived in Wuhan, but type A may not adapt to the local immune system and mutated into type B to cause a large spread.
 
Codename 201 Exercise
According to the official website of "Incident 201", the scene of the exercise at that time was: a new type of zoonotic coronavirus (CAPS) outbreak was simulated. The virus spreads more easily than SARS and may be spread by individuals with mild symptoms. This virus was initially transmitted from bats to pigs, and then to humans, and eventually mutated into human-to-human transmission, leading to a serious epidemic. Why is the plot of the global pandemic exercise so similar to reality?

An official secret document disclosed by the New York Times in March this year showed that from January to August 16, 2019, the U.S. Department of Health and Human Services (HHS) initiated and organized an exercise code-named "Red Infection." The exercise took the first virus in China as a simulation scenario. And as early as October 2019, an event explored the death of a “fictional” global pandemic. The event was called Event 201: Global Pandemic Exercise. The exercise involved "participants" from airlines, health authorities, media, banks and national security agencies. They were subjected to pandemic stress tests to “reveal unresolved and controversial policy and economic issues.” Because the script of the exercise is quite similar to the development of today’s epidemic, it has aroused continuous attention from the international community.

According to the New York Times, the number of biological laboratories in the United States is increasing year by year, but there is a general lack of planning and supervision. The safety of biological laboratories has become the biggest risk faced by US regulatory agencies. According to statistics from the Federation of American Scientists in February this year, there are currently 13 P4 laboratories in the United States that represent the highest level of biosafety in operation, expansion or planning. As far as P3 laboratories are concerned, there are 1,495 in the United States. But the United States has never had a national plan to plan the number of laboratories needed, how to build and operate them. A 2012 article by the US Centers for Disease Control and Prevention used data to show that laboratory safety accidents increased from 16 in 2004 to 128 in 2008, and then increased to 269 in 2010. According to "USA Today" reports, since 2003, hundreds of accidents of human accidental contact with deadly microorganisms have occurred in American laboratories. These contacts may cause direct contacts to be infected with deadly viruses. The viruses spread to communities through these individuals and form epidemics. And this may be the key to unlocking the origin of the virus.
