Science and Technology Daily, Beijing, August 24 (Reporter Liu Xia) According to a report on the US Stars and Stripes website on the 23rd, researchers pointed out that the first death from new coronary pneumonia in the United States appeared nearly a month earlier than the official previously identified.
The latest data shows that from early January to early February 2020, there were 6 deaths of new coronary pneumonia in 6 states in the United States. The date of death is February 6, 2020.
American infectious disease expert and professor emeritus at the University of California, Berkeley, John Schwartzberg, said that the cause of these early deaths was initially believed to be flu.
The new death case data shows that the new coronavirus appeared in the United States as early as December or even November 2019, because it usually takes 3 weeks for a patient to die from infection with the virus, which will greatly change the timeline for the spread of the new coronavirus in the United States.
On February 6, 2020, Patricia Dowd, a resident of San Jose, USA, passed away. She is believed to be the first death from the new crown in the United States.
However, the latest data provided by the National Center for Health Statistics (NCHS) under the US Centers for Disease Control and Prevention shows that from January 5 to 11, January 12 to 18, January 19 to 25, and January 26, 2020 From January to February 1, there were 1, 2, 2, and 1 deaths from new coronary pneumonia in the United States, respectively, in California, Alabama, Georgia, Kansas, Oklahoma, and Wisconsin. , Both as early as February 6.
NCHS is widely regarded as the definitive source of death data in the United States.
According to the researchers, these data show that the new crown virus soon appeared in the interior of the United States and the deaths were widely distributed, while Alabama and Oklahoma usually rarely have travel records to and from China, which indicates that the new crown virus The virus spread much earlier in the United States.
These new data are the result of months of hard work by coroners, medical examiners, and doctors. The purpose is to more closely examine the deaths in the United States in the months before the outbreak of the new crown epidemic.
The Bay Area News Corporation first reported in April that the CDC was investigating why there were multiple new coronavirus-related deaths in state and federal records before Dodd's death.
At the time, most of the data was interpreted as incorrect dates or other data errors.
Robert Anderson, the head of the NCHS's death statistics department, said that the person who issued the death certificate usually does not modify the death certificate unless there is a good reason.
John Schwartzberg pointed out that the first death from new coronary pneumonia in the United States appeared several weeks earlier than the official confirmation.
He said: “(The new crown virus) appeared in the United States long before it was considered a problem.”
Matthew Memorly, director of the Clinical Trials Laboratory of the National Institutes of Health's Infectious Diseases Laboratory, agrees, and his team is conducting research on thousands of people across the country.
Their research shows that as of July 2020, each known case corresponds to 5 or more unknown cases.
Memorly said this information suggests that the virus may spread earlier than previously thought.
The CDC's analysis of thousands of blood samples from 9 states also came to the same conclusion. These samples were collected by the American Red Cross between December 2019 and January 2020, and the researchers included them. Evidence of the existence of antibodies to the new coronavirus was found.
