          Abstract

          Las epidemias o brotes pueden ser definidos como un exceso en el número de casos de un problema de salud dado, en una población, un período y un lugar en particular. Sin embargo, determinar lo que constituye un exceso implica conocer lo que es normal o de esperar. La elaboración de canales o corredores endémicos permite definir los valores de casos esperados y de esta forma evidenciar de forma gráfica la aparición de un nú mero mayor de casos. En el presente trabajo se describe una nueva metodología para la realización de estos canales endémicos, en la que se utilizan las planillas de cálculo Qpro y Excel, mediante la determinación de la media geométrica de lastasas históricas y su in tervalo de confianza. Se presenta también un corredor endémico acumulativo que facilita la vigilancia de sucesos endémicos de baja incidencia.

          Translated abstract

          Epidemics or disease out breaks can be defined as an excess in the number of cases of a given health problem, in a particular population, period, and place. However, to determine what constitutes an excess implies knowing what is normal or to be expected. Establishing endemic levels or ranges makes it possible to determine figures for the number of expected cases and to show in graphic form the appearance of a higher number of cases. In this work a new methodology is described to develop these endemic ranges, in which the Quattro Pro (Qpro) and Excel software programs are used to calculate the geometric mean of historical rates and their confidence intervals. Also presented is a procedure for cumulative endemic ranges that facilitates surveillance of endemic events with a low incidence.
