Thus far, 2019 has been a year marked by several dengue epidemics, from Latin America to Southeast Asia. Data from the Pan American Health Organization (PAHO) indicate about 236,372 total possible cases, with nearly 80,000 laboratory-confirmed cases and 68 deaths this year in the Americas alone. The current total 2019 cases for the region is estimated to already be 42% of the total 2018 cases (561,233 cases), indicating that 2019 totals may potentially surpass those of 2018. This week, Outbreak Observatory explores dengue epidemiology and several challenging factors that are limiting our ability to control this disease.
