Dengue cases in Brazil 2015-2024
Dengue fever poses a significant public health challenge in Brazil. During the first months of 2024, the South American country reported over five million dengue cases, a higher number of infections than those observed from in the whole of 2023 and a significant increase in comparison to previous years. This is the result of the cyclical nature of the disease, which flares up every two to five years, as well as of a variety of socio-economic and climate-related components.
Dengue in Latin America
Latin America is one of the regions most affected by dengue in the world, with South American countries having some of the highest dengue incidence rates reported. As of April 2024, Paraguay, Brazil, Argentina, and Peru had rates ranging between 400 and 3,000 cases per 100,000 population. These figures are influenced by the seasonal nature of the disease, where cases tend to peak at different times of the year depending on an array of regional characteristics.
Tropical diseases in Brazil
Brazil is the Latin American country with the highest number of dengue, Zika, chikungunya, and malaria infections. The South American nation is the most populated country in the region and considered the one with the highest physical exposure to vector-borne diseases, and among the most exposed to epidemics in Latin America and the Caribbean. This results from a combination of geographic and socio-economic factors relevant to the spread of these diseases.
