Model obtained using generalized linear models by taking into account the possible correlation between individuals in the same municipality, and OR adjusted for season, age group, sex, education, chronic diseases, low birth weight, swimming outdoors and for all of the variables included in the table. Swimming outdoors was not included in model for bacterial or parasite infection.
Density by cultivated area for the municipality.
