How early did local transmission of the SARS-CoV-2 infection start in the United States? The CDC scientists came to a different conclusion after examining data from 4 sources: hereditary series; retrospective testing of saved influenza security samples; a review of emergency room records from counties that had early cases of COVID-19; and the retrospective discovery of two individuals in California who died from Covid-19 in mid-january and early, and a contaminated cruise ship team member who departed from San Francisco on Feb. 11. The quotes of when the infection in fact started sending in the U.S. might alter again, Armstrong stated, keeping in mind pathologists continue to examine suspicious deaths from early in the year and to send out samples to the CDC for analysis.
How early did local transmission of the SARS-CoV-2 infection begin in the United States? If COVID-19 cases were being mistaken for flu in the early days of the outbreak, one would have anticipated to have actually seen some positive tests amongst those samples. The CDC scientists came to a various conclusion after analyzing information from four sources: hereditary series; retrospective screening of saved influenza surveillance samples; a review of emergency room records from counties that had early cases of COVID-19; and the retrospective discovery of 2 individuals in California who died from Covid-19 in mid-january and early, and an infected cruise ship team member who left from San Francisco on Feb. 11. The mix of those information sources led the CDC group to conclude community transmission in the U.S. began in late January or early February. The price quotes of when the infection actually began transmitting in the U.S. might alter once again, Armstrong said, keeping in mind pathologists continue to investigate suspicious deaths from early in the year and to send samples to the CDC for analysis.
