In order to gain insight into the distribution of cholera over the years and proportion of monthly admissions under our adult medical services, we scrutinized our records of hospital discharges between 1989 and 1994. Only culture positive cases were included. Each year most of the cases of cholera are admitted between May and November with almost disease free interval from December to April. In 1992 admission rate was 4.24/1000 medical admissions which increased to 12.65 in 1993 and 13.73 in 1994. Though the Vibrio cholerae 01 Ogawa was the major isolate upto May, 1993, Vibrio cholerae non-01 serogroup 0139 dominated between June and August, 1993. Ogawa strain re-established itself in October, 1993. In August, 1994, non-01 strain reappeared and became the major isolate in September. Cholera has caused multiple epidemics throughout the Indian subcontinent. Since 1800, there have been seven pandemics of cholera. The seventh pandemic originated in Indonesia and continues today.
