Between January and November 2017, reports of Dengue fever, a disease transmitted by the mosquito Aedes aegypti, fell 83.7 percent in relation to the first eleven months of 2016. As for the deaths caused by these diseases, the fall was 82 percent.
As for Zika’s records, they were 92.1 percent lower than last year, with a incidence rate fall from 103.9 per 100 thousand inhabitants in 2016, to 8.2 per 100 thousand inhabitants in 2017. Chikungunya also followed this downward trend and declined by 32.1%.
Data from the Rapid Survey of Infestation Rates by Aedes aegypti (LIRAa) helped to identify neighborhoods and critical areas of mosquito breeding sites where larvae were found.
Actions to control the disease focus on locating and eradicating foci of larvae in urban areas and the use of larvicides such as Malathion and Pyriproxyfen.
