In the face of the worst yellow fever outbreak in decades, Brazilians waited hours at a time for vaccinations against the fatal disease in January this year. But yellow fever is far from the only mosquito-borne disease to sweep across the continent. In the last five years alone, Brazil has had serious outbreaks of three threatening arboviruses: Chikungunya, dengue, and the Zika virus.
Most recently, data from the Ministry of Health showed that the Amazon region has registered a 50-percent increase in the number of malaria cases from 2016 to 2017. Last year, the region recorded 194,000 cases; the trend looks set to continue into 2018, with 17,000 cases in January this year. This rapid incline has come as a shock to the Brazilian government, which celebrated a 29 percent decrease in cases as recently as 2015.
