November 2 New Media Special News According to a report on October 26 by the US “Science Daily” website, the outbreak of Coronavirus in New York and Long Island started earlier than previously thought, and many people were infected with viruses from Europe. Strain.
A new analysis also shows that most of the transmission is within the community, not from people who have traveled.
According to the report, the previous test found the first confirmed case of Coronavirus on March 3. After that, a large-scale infection broke out throughout New York. By mid-May, there were 260,600 confirmed cases.
This new study was led by researchers from the New York University School of Medicine, using genetic testing to trace the source of the new coronavirus that spread throughout New York City in the spring.
The results showed that the new coronavirus took root for the first time at the end of February, but it did not come from a single “patient zero” but from at least 109 different sources, which subsequently detonated multiple chains of infection.
It is worth mentioning that the author of the research report stated that more than 40% of people who tested positive for the Coronavirus had no known history of contact with other people infected with Coronavirus before the diagnosis.
“Our research results show that the early screening methods in New York City have been delayed for at least a few days in determining the source and start of the outbreak,” said the co-first author of the research report, Matthew, an assistant professor at NYU Langon Medical Center.
Dr. Maurano said, “This research strongly shows that in order to eliminate future pandemic in their budding state, we need a fast and massive real-time genetic monitoring system in addition to monitoring traditional epidemiological indicators.”
The research was published in the online edition of the journal Genome Research on the 22nd.
Research also shows that the genetic sequence of the virus in New York is more consistent with the strains in Europe and other states in the United States, rather than the strains in China.
In addition, some early human-to-human infection chains reached more than 50 people.
