Throughout the first half of the year, the epidemiological situation of dengue has presented a very unstable feature, with severe outbreaks of dengue in several countries in the region. Weather conditions have been very flattering to the proliferation of the vector Aedes aegypti and some unusual changes in the seasonality of dengue have been registered affecting since the beginning of the year to Central America and the Caribbean islands during periods considered unusual.
The rainy season is coming in the Central American sub region and the Caribbean, so it is expected and is already seeing an increase in dengue transmission that can potentially affect large population groups even in areas where the problem was not either because they were often protected by cold weather conditions or because there was delay in the entry of the cold season, with which the vector could not survive.
