Why map dengue cases?

Historical data can provide information on consistent dengue virus transmission hot-spots to be targeted in proactive vector control schemes

Historical data can provide information on consistent dengue virus transmission hot-spots to be targeted in vector surveillance schemes

Dengue clusters (2 or more cases per location)

Dengue sensitive areas

Locations where ovitraps are placed

Mapping can provide a better understanding of the spatiotemporal dynamics of dengue outbreaks and help guide spatial implementation schemes for emergency vector control
