ABSTRACT

Bakcground: On October, 1988 the fi rst major dengue outbreak was reported in the city of Guadalajara, Mexico caused by serotype 1. Objective: identified de main risk factos in a family and individual level. Method: A survey conducted in a sample of the aff ected area. In addition data of 337 households and 1959 persons were collected. Th e Relative Risk (RR) was calculated at the individual and family level, as well as the Population Atributable Risk% (PAR%) according to the type of breeding sites in the households. Results: The main risk factors in the famiily level were bottles and tin can positives for Aedes aegypti (RR= 3.2 y 2.7), small incidental containers (RR= 2.5) and cement water reservoirs positives for A. aegypti (RR=2.2). Th e risk of illlness in households with containers positive was 2.2. In the individual level females more than 45 years old reports RR=5.7. In addition three and more breeding sites in the house presents a significative risk factor (RR=3.3). The only protective factor identified in a family level was the presence of net in the house. No protective factors were identifi ed in an individual level. Th e PAR % for cement water containers was 38.2 %, 200 lts water containers 22.2 % and incidental water containers = 20.2 %. Conclusions: The main risk factors identified at family level were the presence of bottles and positive ontainers of larvae of A. aegypti followed by the presence of positive pots and pans. At the individual level, belonging to the female sex and being over 45 years old meant a high risk to acquire dengue. Th e highest RAP% was for the pools, followed by 200 lts drums. Th e estimation of the PAR%, allows focused the control activities in a more eff ective way.
