Study Examines Factors Contributing To 2017 Decline Of Dengue Incidence In Americas

Tropical Medicine & International Health: The Decline of Dengue in the Americas in 2017: Discussion of Multiple Hypotheses
Steven Ault, adjunct instructor in the Department of Epidemiology and Biostatistics at the University of Maryland, and colleagues examine the decline in reported dengue cases in the Americas in 2017, writing, “Understanding the mechanism underlying dengue’s incidence and decline in the Americas is vital for public health planning. We aimed to provide plausible explanations for the decline in 2017.” The authors conclude, “Multifactorial events may have accounted for the decline in dengue seen in 2017. Differing elements might explain the reduction in dengue including elements of immunity, increased vector control, and even vector and/or viruses changes or adaptations” (1/9).
