About the Cover
The visualization shows a dengue density choropleth map of Cavite province in the Philippines depicting the dengue cases distribution across the geographical area, from 01 Jan 2016 to 31 Dec 2020. The illustration was rendered via Python 3.9.12 Matplotlib visualization library. The study by Acosta and Nacion identified six distinct risk classifications in particular—(1) persistent, (2) sporadic, (3) intensifying, and (4) diminishing hotspots, as well as (5) persistent, and (6) sporadic coldspots. The authors recommend alleviating the overall burden of dengue fever in the province through intervention strategies by public health authorities that are tailored to different areas and at different times.
