The virus is now known to spread from human to human. How easily is not yet determined. Any given virus can spread reluctantly or be highly contagious. Measles, for example, is far more contagious than early analyses of this coronavirus indicate, says Nancy Messonnier, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases.
