[Dengue prevention and control: a review of studies on knowledge, beliefs, and practices].

This article aims to contribute to dengue control programs through a review of recent studies on knowledge, beliefs, and practices concerning dengue and dengue prevention. The results show that adequate knowledge of dengue and prevention methods are found in close association with high rates of domiciliary infestation by Aedes aegypti. This suggests that traditional education strategies, although efficient in transmitting information, have failed to change population behavior.

[Demographic and mortality trends in Niterói, Rio de Janeiro, Brazil, 1979 to 1997].

An analysis of the 1979-1997 historical series points to demographic and mortality trends in Niterói, Rio de Janeiro State, over the course of those two decades. There was a drop in the rate of population increase, with a significant change in the age structure. In the time series, there was a decline in mortality from cardiovascular diseases and an overall downward trend in mortality from infectious and parasitic diseases, albeit with a sharp increase beginning in 1996 resulting in a change in disease classification (ICD-9 to ICD-10).
