Leptospirosis outbreak following severe flooding: a rapid assessment and mass prophylaxis campaign; Guyana, January-February 2005.

Background: Leptospirosis is a zoonosis usually transmitted through contact with water or soil contaminated with urine from infected animals.

Rapid testing for the disease and large-scale interventions are necessary to identify and control infection.

An outbreak of enterotoxigenic Escherichia coli associated with sushi restaurants in Nevada, 2004.

Background: In August and November 2004, 2 clusters of diarrhea cases occurred among patrons of 2 affiliated sushi restaurants (sushi restaurant A and sushi restaurant B) in Nevada.

Nonfoodborne Vibrio infections: an important cause of morbidity and mortality in the United States, 1997-2006.

Background: Infections due to Vibrio species cause an estimated 8000 illnesses annually, often through consumption of undercooked seafood. Like foodborne Vibrio infections, nonfoodborne Vibrio infections (NFVI) also result in serious illness, but awareness of these infections is limited.

Methods: We analyzed illnesses occuring during the period 1997-2006 that were reported to the Centers for Disease Control and Prevention's Cholera and Other Vibrio Illness Surveillance system.
