This article discusses the results of a reading-and-appropriation study, as an approach methodology to narrative universe of Health Community Agents (ACS), using the Dengue Almanac (AD), an information-communication device. Workshops with groups of ACS from Rio de Janeiro city were developed using the Almanac, aiming it's de-construction and relational reading, to improve the comprehension about knowledge's construction and appropriation on dengue and health, and evaluate the AD as an info-communicational device. The results were categorized within three axes: informational abundance during dengue's epidemics and silence between them, meaning non-information; the victim's blaming in health information's processes; ACS labor's contradictions and ambiguities as mediators. The Almanac proved to be a useful tool to discussion and appropriation of health information, due to the relational and non-linear reading characteristics of it's contents, and the interactive and nonauthoritative format of it's formulations on dengue and health.
