A top Centers for Disease Control and Prevention (CDC) official said it is preparing for the new coronavirus, officially known as COVID-19, to take “a foothold” inside the United States.
“At some point, we are likely to see community spread in the U.S. or in other countries,” Dr. Nancy Messonnier, the head of the CDC’s National Center for Immunization and Respiratory Diseases, told reporters during a conference call. “This will trigger a change in our response strategy.”
