Abstract :

 Introduction Cholera is an acute diarrheal disease causing high mortality and morbidity in the Indian subcontinent .On July 11 th of  2014 a case of cholera was confirmed by bacteriological examination from Ettumanoor town area.. An outeak investigation was conducted with the objective of describing the epidemiological characteristics of the outeak. Methodology:A house to house survey was conducted  for active case searching and identifying  socio demographic factors which lead to the outeak. A spot map was constructed to identify clustering of cases. An epidemic curve was drawn to characterise the time trends. Water from suspected sources was tested for cholera. Results .The epidemic curve had a sharp rise and fall with no further cases.. Attack rates among individuals consuming food from Restaurant A was 25% and Restaurant B was 33.3%. Conclusion The outeak is a single exposure epidemic and failed to propagate possibly because of effective control measures. The high attack rates among people who ate from suspected food outlets indicate the source of infection to be either food or water consumed. A common food item which was served raw and sourced from the same supplier could have been the source of infection.
