Imported plague--New York City, 2002.

On November 1, 2002, a married couple traveled from Santa Fe County, New Mexico, to New York City (NYC), where they both became ill with fever and unilateral inguinal adenopathy; bubonic plague (Yersinia pestis) was diagnosed subsequently. This report summarizes the clinical and public health investigation of these cases and underscores the importance of rapid diagnosis and communication among health-care providers, public health agencies, and the public when patients seek medical attention for an illness that might be caused by an agent of terrorism.
