Abstract
This study aims at measuring the dengue fever infection incidence in Paraíso City in the state of São Paulo due to an outbreak occurred in April, 1993. The serological survey showed an incidence of 3,7%, which indicates that aproximately 180 people could have been infected by the vírus during the outbreak. These data show that the symptomatic ratio is of 1:12, that is, for each case laboratorially diagnosed there were 11 without any diagnosis. A relationship between symptomatology and positive serology was found. Symptoms such as fever, headache and sore muscles were the most recalled ones. There was no statistically significant difference regarding age, sex, occupation and social-economical
level. It is also important to highlight that 33% of the positive individuals detected by the survey didn’t report any symptom.
