List of early cases of COVID-19 in the United States

From Wikipedia, the free encyclopedia

This is a list of early transmissions of coronavirus disease 2019 (COVID-19) in the United States, covering cases that occurred in January and February 2020.

By the end of February, 24 cases were known, a number that had increased to 27,368 by the end of March, and continued to grow over the year. The outbreak evolved into a severe pandemic over the course of the year, with extremely rapid growth in cases after that point.[1] In addition to those 24 cases known by the end of February, this list includes three cases which were confirmed later by phylogenetic analysis and post-mortems for a total of 27 cases. This list does not include repatriated cases- such as the fourteen infected citizens brought back from the Diamond Princess in February.[2]

Limited testing at the time means that it is likely there were additional undetected cases. Dr. Sara Cody, medical officer for Santa Clara County (which saw a number of the first cases) stated that those confirmed at the time represented only "the tip of an iceberg".[3][4]
