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.

 

"A series of previous studies showed that the United States, Spain, France, Italy, Brazil and other countries had been attacked by the coronavirus before its outbreak in China," the researchers wrote.

 

After analyzing daily epidemic data published by local health authorities from 11 US states and the District of Columbia, the researchers said they are 50 percent confident that the first COVID-19 cases in the US emerged between August and October 2019, considerably earlier than the currently acknowledged date of the first confirmed US case, on Jan 20, 2020.
