Pattern of cholera in Raipur: a twelve year appraisal.
Outbreaks of cholera were recorded in Raipur in the years 1970, 1975, 1977 and 1979-1981.  Change from V. cholerae classical inaba in 1970 to V. el tor ogawa in 1974 was also observed.  The el tor strain is persisting in this area since then.  In 1977, antigenic shift to V. el tor inaba was recorded but it again reverted to el tor ogawa which was responsible for outbreaks in 1979-1981.  V. cholerae was isolated in most of the months in the years 1975, 1977 and 1980.  Almost equal prevalence rates were seen in both sexes as well as in paediatric and adult groups.  NAG vibrio were also inoculated.  These data suggest endemicity of choloera in Raipur.
