This paper by National Institute of Cholera and Enteric Diseases (NICED) is based on a prospective, community based study in an impoverished urban site in Kolkata in order to measure the burden of cholera, describe its epidemiology, and search for potential risk factors that could be addressed by public health strategies. The study population was enumerated at the beginning and end of the study period. Surveillance through five field outposts and two referral hospitals for acute, watery, non-bloody diarrhoea was conducted from May 2003 to April 2004.
