From: The overlapping global distribution of dengue, chikungunya, Zika and yellow fever
a The global number of new unique occurrence points added each year (i.e. after thinning). Years with sparse (n < 100) occurrence records (1927–1984) are not shown. b–e global maps of occurrence data for dengue (b), chikungunya (c), Zika (d) and yellow fever (e).
