Provincial COVID-19 mortality rates and altitudes, Ecuador. In this map of Ecuador, the provinces with brown borders represent Costa region, blue borders Sierra region, and purple borders AmazĂ³nica region. The provinces are divided in five categories based on the altitude of the capital of those provinces in meters and are represented in light to dark green. Mortality rates due to COVID-19 in each of the provinces were categorized into five levels (0–15, 15–30, 30–45, 45–60, 60–90) and are presented with ascending size of red dots. The right lower corner shows a map of South America with Ecuador highlighted in red
