[Dengue prevention: focus on information].

The first three months of 2002 witnessed a dengue epidemic in the State of Rio de Janeiro. At that time, health authorities encouraged community participation in the elimination of vector breeding sites. For this campaign, a great quantity of information about the disease was extensively publicized in order to guide the population's preventive action. This paper analyzed the three pamphlets most widely distributed at that time in Rio de Janeiro city considering that this information contributed to the construction of disease representation and its prevention. It was observed that even though this information was provided repeatedly it must be revised.
