*One year ago, on January 20, the first coronavirus case in the U.S. was confirmed by the Centers for Disease Control and Prevention. A man in Washington state tested positive for the virus after returning from Wuhan, China, where the pandemic outbreak originated.
The following day, Dr. Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, said during a call with journalists that “the risk to the American public is low,” but more information on the virus was developing daily.
