Cityscape: Typhoid Mary

Her story reads like a Hollywood film: A woman who seems healthy is quarantined on a remote island off New York City because it’s feared she’s spreading a deadly disease. Mary Mallon – better known as Typhoid Mary -- spent much of her life quarantined on North Brother Island.  So close, but yet so far away from the hustle and bustle of Manhattan.  She was the first known healthy carrier of typhoid fever. Author Mary Beth Keane penned a novel based on Mary Mallon's life. It's called "Fever," and we're talking with her on this week's Cityscape.
