%X Considerando el bajo reporte de enfermos de c車lera y con el prop車sito de conocer la realidad del problema en el Distrito Villa El Salvador, de la introducci車n de Vibrio cholerae (V. cholerae) en Per迆, se tom車 una muestra de 101 casos con enfermedad diarreica aguda (EDA) seleccionados por un muestreo sistem芍tico a partir de un arranque aleatorio definido para cada unidad asistencial del Distrito, seg迆n la ocurrencia promedio diaria de casos con EDA atendidos respectivamente durante la semana precedente a la realizaci車n del estudio. A todos les fue llenada una encuesta epidemiol車gica, se les tom車 tambi谷n una muestra por hisopado rectal para aislamiento de V. cholerae, se encontraron 53 casos positivos (52,2 % y un intervalo de confianza entre 42,29 y 62,5 %) con diferencias significativas (p < 0,01) entre la frecuencia en adultos (67,3 %) respecto a los ni os (34,8 %). S車lo en 13 (61,9 %) de los 21 casos con antecedentes de contacto con enfermos de c車lera se aisl車 V. cholerae, para un riesgo relativo de 1,24 (0,83Taking to consideration the low report of cholera patients and with the main knowing the reality about the introduction of Vibrio cholerae (V. cholerae) in Peru, a sample of 101 cases with acute diarrheal disease (ADD) was taken at the Distrito Villa El Salvador. They were selected by a systematic randomized sampling defined for each health care unit in the District, according to the daily average occurence of ADD cases attended a week before the beginning of the study. All of them took part in a epidemiological survey. A sample was taken by rectal swab in order to isolate V. cholerae. 53 positive cases were found (52.2 % and a confidence interval from 42.29 to 62.5 %) with significant differences (p < 0.01) between the frecuency in adults (67.3 %) and children (34.8 %). V. cholerae was isolated only in 13 (61.9 %) of the 21 cases who had contact with cholera patients, for a relative risk of 1.24 (0.83 < RR < 1.85). A high positivity was also found, 21 cases (72.4 %) among those who had raw food. A significant difference (p < 0.01) was observed in connection with those who had cooked food. In the multivariate logistic regression analysis it was only found a significant relationship with age and with the ingestion of raw food as regards the occurrence of cholera.
