Intro.: A Moment in Time with Dan Roberts.

Content: Many immigrants arriving in New York Harbor were not aware that they would need to pass medical and legal examinations before they were granted permission to enter. The first test came even before the steamship docked. U.S. government doctors would board the ship and check for contagious diseases: smallpox, yellow fever, measles. Infected passengers were removed (taken to hospitals) and the ship was quarantined until it was safe. After docking in Manhattan, ferryboats or barges would transport immigrants to Ellis Island. There they were tested to determine if fit to enter America.
