Novel Coronavirus from New York City, the “novel coronavirus” hit hardest by the COVID-19 outbreak in the United States, was originally introduced mainly from Europe and other parts of the United States, according to a new study published in the Journal Science.
Researchers at the Icahn School of Medicine in Mount Sinai in the United States sequenced the viral genome of 84 early coVID-19 patients in New York.
The patients were admitted to mount sinai medical system in New York on February 29 solstice and March 18.
The analysis showed that novel Coronavirus was originally introduced to New York mainly from Europe and other parts of the United States and was introduced from multiple independent sources.
The majority of coVID-19 cases in New York in the early stages are likely to have been infected through untraced transmission sources and associated travel history.
The researchers also found that community transmission accelerated the spread of the disease after early coVID-19 cases in New York.
The effect of the travel restrictions was limited when New York confirmed that Novel Coronavirus had been introduced from multiple independent sources and had community spread.
“Understanding the viral path of novel Coronavirus is critical to assessing the epidemic and planning effective containment measures,” AAAS said in a statement.
This study underscores the importance of continuing to strengthen virus testing to detect untraced transmission sources in the community as early as possible.
