Dengue exhibits episodic major outbreaks every three years or so, the most recent being in 2010 and in 2007. On top of this trend, the past decade has seen a steady increase in the basal levels of disease. In the case of Brazil, the basal level has increased roughly 3-fold over the past decade. These trends result, in large part, from the complex population dynamics of the disease vector, the Ae. aegypti mosquito.

 

The Ae. aegypti strain is making a comeback in the Americas with its furthest waves lapping onto N. American shores.

Notes:

  ° - Data from Pan American Health Organization/WHO; weblink

  * - "Total" refers to the total number of reported cases of dengue; these cases are not necessarily lab-confirmed;   "SD" refers to severe disease, namely dengue hemorrhagic fever (DHF) & dengue shock syndrome (DSS). "YTD"  is year-to-date.

 

Notes:

  This figure shows the dengue "severe disease index" (SDI; calculated as the % of severe disease cases (DHF & DSS) among all dengue cases that year). The SDI is plotted over the past decade for three representative countries in the Americas: Honduras, Brazil, and Puerto Rico. Note that Honduras has had an unusually high SDI, especially 5 of the 7 past years.
