Recently, a prototype dengue early warning system was developed to produce probabilistic forecasts of dengue risk three months ahead of the 2014 World Cup in Brazil. Here, we evaluate the categorical dengue forecasts across all microregions in Brazil, using dengue cases reported in June 2014 to validate the model. We also compare the forecast model(More)

BACKGROUND With more than a million spectators expected to travel among 12 different cities in Brazil during the football World Cup, June 12-July 13, 2014, the risk of the mosquito-transmitted disease dengue fever is a concern. We addressed the potential for a dengue epidemic during the tournament, using a probabilistic forecast of dengue risk for the 553(More)
The authors describe three recent experiences of epidemiological surveys of zoonotic diseases in Brazil. The role of spatial data acquisition and analysis has been reinforced, considering the intrinsic complexity of environmental and social factors affecting transmission. Health surveillance in Brazil is undergoing a decentralisation process, in accordance(More)
Homicide mortality remains a major public health problem in Brazil, especially among young adult males. The aim of this study was to assess the homicide mortality risk (HMR) among males aged 20 to 39, and its association with selected socio-demographic characteristics of the Brazilian municipalities. This is an ecologic study in which all the municipalities(More)
