Global disease, vector and transmission-risk models.
A: maps for the late 20th century. B: maps for the early 21st century. The risk of transmission is estimated as the intersection (∩) between favorable conditions for the occurrence of dengue cases and favorable conditions for the presence of vector species. The spatial resolution is based on 7,774-km2 hexagons. Recorded occurrences of dengue cases and vector presences are also mapped.
