BEIJING, Sept. 22 (Xinhua) -- Chinese researchers have discovered by employing big-data analysis that the COVID-19 pandemic in the United States might have started to spread around in September 2019, earlier than the officially announced date of its first confirmed case.
A study of big data and epidemic models indicates with 50 percent probability that the first COVID-19 infection in the United States may have occurred between August and October 2019, and the earliest possible case was on April 26, 2019, in Rhode Island, according to a preprint of a study published on Wednesday. The study, conducted by researchers from the University of Science and Technology of China and the University of Chinese Academy of Sciences, is published on the Chinese preprint server ChinaXiv and is still undergoing peer-review.
