Abstract
The introduction of cholera into many of the islands of the Philippines in 1961 often occurred in an explosive manner. The disease was introduced into Bacolod City and Talisay in Negros Occidental Province in such a manner in November 1961. The authors describe the results of an analysis of hospital and health department records in Bacolod City and Talisay and the results of interviews conducted with adult patients 10 months after the explosive outbreak.
The results suggest that infection during the initial explosive wave of cases in Bacolod City and Talisay in November 1961 was transmitted principally by shrimp that were consumed raw.
