Resumen
Introducción

Se presentan los resultados de los distintos estudios realizados en la investigación de un brote de gastroenteritis y se exponen las dificultades y las limitaciones que condicionaron su estudio.

Métodos

Se diseñaron varios estudios analíticos: un estudio de cohortes y un estudio de casos y controles con diferente tamaño muestral.

Resultados

De los 189 participantes, el 43% respondió el cuestionario. Se identificaron 45 casos. Los factores que se asociaron significativamente con la enfermedad fueron: la cena del día 11 de diciembre en uno de los restaurantes del complejo, tanto en el estudio de cohortes como en el de casos y controles, y la excursión a una isla cercana en el de cohortes.

Discusión

Se confirmó la existencia de un brote, aunque debido a la baja tasa de respuesta y las dificultades para entrevistar a los participantes del viaje, no fue posible identificar la vía de transmisión.

Abstract
Background

We present the results of different studies performed in the investigation of a gastroenteritis outbreak and we describe the difficulties and limitations encountered during its study.

Methods

Several analytical studies were designed: one cohort study and one case-control study with different samples sizes.

Results

Of the 189 trip participants, 43% answered the questionnaire. Forty-five cases were identified. The factors significantly associated with the disease were: dinner in one of the restaurants of the resort on December 11 in all analytical studies and the excursion to a nearby island in the cohort study.

Discussion

The outbreak was confirmed however due to the low response rate and the problems encountered to interview the participants in the trip, it was not possible to identify the route of transmission.
