U.S. Epidemiologists: Studies have shown that the new crown pneumonia has spread in the United States in December of the previous year
According to the research results recently published by the National Institutes of Health, the new crown virus has been in the United States in December 2019 spread. Dennis Carroll, chairman of the Global Virology Project and former director of the Global Pandemic Viruses and Potential Threats Department of the United States Agency for International Development, said in an exclusive interview with a CCTV reporter that the results of this study are credible.
According to a study by the National Institutes of Health, researchers collected 24,000 blood samples from all over the United States in early 2020. Testing of these blood samples showed that as early as December 2019, the new crown virus had spread at a low level in the United States.
Chairman of the Global Virology Program USAID Dennis Carroll, former head of the Department of Global Pandemic Viruses and Potential Threats: This is consistent with the reports we have seen from Europe and even other reports from the United States. These reports indicate that the spread of the new coronavirus was earlier than the time of the initial (official) report, which is the end of January (2020).
Dennis Carroll said that the issue of the origin of the new crown virus has become a hot topic, but sadly, it did not appear as a public health issue, but was used as a political weapon. It is a kind of harm to everyone.
Chairman of the Global Virology Program USAID Dennis Carroll, former director of the Department of Global Pandemic Viruses and Potential Threats: In fact, it has become a hot spot of public opinion. And now that it has been involved in politics, it is no longer a public health issue. In the absence of evidence, we have different opinions. Unfortunately, these opinions are driven more by politics than goodwill.
Dennis Carroll also expressed the hope that the United States can cooperate with China and other countries so that everyone in the world can obtain vaccines and end the epidemic as soon as possible.
Chairman of the Global Virology Program USAID Dennis Carroll, former director of the Department of Global Pandemic Viruses and Potential Threats: I hope that the United States can work with China and other countries to truly propose a global strategy. We work together to make these vaccines available to everyone.
New crown infection may have appeared in the United States in December 2019
In addition to the report published by researchers from the National Institutes of Health on May 15, researchers from the Centers for Disease Control and Prevention A report was also issued at the end of the year, stating that there may have been individual cases of new crown infection in some parts of the United States in December 2019.
On November 30, 2020, researchers from the U.S. Centers for Disease Control and Prevention reported in the bimonthly “Clinical Infectious Diseases” that in December 2019, some American blood donated samples had antibodies to the new coronavirus. This means that the new coronavirus may have appeared in the United States at that time, earlier than the time when the first confirmed case of new coronary pneumonia was officially reported by the United States.
U.S. Centers for Disease Control and Prevention The Red Cross collected 7,389 blood samples from December 13, 2019 to January 17, 2020. These samples came from blood donors in 9 states across the United States. The results found that 106 blood samples contained antibodies to the new coronavirus, of which 39 samples were from California, Oregon and Washington, and were collected from December 13 to December 16, 2019; 67 samples were from Massachusetts and Michigan In states and other places, the collection time is from December 30, 2019 to January 17 last year.
The first confirmed case of new coronary pneumonia was reported in the United States on January 21, 2020. Studies have speculated that there may have been individual cases of new coronavirus infections in some parts of the United States in December 2019.
The new crown virus may have spread in Los Angeles before the official report in the United States
In September and October 2020, the University of California, Los Angeles issued a press release stating that it began in late December 2019 , The proportion of patients with cough and acute respiratory failure symptoms admitted to the school’s medical institutions has increased significantly compared with previous years.
Researchers speculate that the symptoms of these patients are similar to those of new coronary pneumonia. The new crown virus may have spread in Los Angeles before the first confirmed case officially confirmed in the United States.
Research by the University of California, Los Angeles and the University of Washington The staff published a paper in the Journal of Medical Internet Research, stating that they evaluated more than 10 million patient electronic health records in medical institutions affiliated to the University of California, Los Angeles from December 1, 2019 to February 29, 2020. Comparison of records in the same period of 5 years. The results found that from December 1, 2019 to February 29, 2020, the proportion of patients who went to general outpatient clinics due to cough increased abnormally, which was an increase of more than 50% compared with the average level of the same period in the previous five years, which is equivalent to an abnormal increase of 1,000 Multiple cases. In addition, the proportion of cough patients reported by the emergency department and acute respiratory failure patients reported by the inpatient department has also increased significantly compared with the same period in the previous five years.
Researchers believe that even considering the number of patients Factors such as changes and seasonal changes still have an abnormal increase in cases. This indicates that the new coronavirus may have spread in communities in the United States before the United States has clinical understanding of the new coronavirus and has the ability to detect it.
However, the researchers also said that the abnormal increase in cases may also include other reasons such as e-cigarette use and flu. Whether these abnormally increased cases are early undetected cases of new crowns in the Los Angeles area still needs further research and inspection.
