First COVID-19 case in the USA reported a year ago

A year ago today (January 20), authorities identified the first case of COVID-19 in the United States. Since then, the country has recorded more than 24.2 million cases and more than 400,000 people have died of the virus.

The first known case in the U.S. involved a 35-year-old man who traveled to Wuhan, China, to visit his family and returned to Washington state on January 15, according to The New England Journal of Medicine. Four days after returning, he went to an emergency clinic in Snohomish County with a cough and what appeared to be a fever. The clinic and the Washington Department of Health collected samples and notified the Centers for Disease Control and Prevention (CDC); the CDC confirmed that he had COVID-19 a day later, on January 20th.
