Incidence of notified dengue hemorrhagic fever in untreated, partially treated and fully treated kelurahans. Kelurahans were defined as ‘untreated’ prior to the commencement of wmel releases, ‘partially treated’ when releases have commenced in any part of the kelurahan or wMel contamination has occurred (kelurahan-level wmel frequency was >50% for two monthly monitoring events within a 6-month rolling window and >50% of the BG traps in the kelurahan have detected wMel-positive Ae. aegypti during those monitoring events), and ‘fully treated’ once wmel releases were completed in all parts of the kelurahan.
