Figure 16. Dengue case notifications per month, January 2000 – March 2019, in four local government areas where Wolbachia mosquitoes have been released.

Notifications include laboratory-confirmed and probable dengue cases, classified as locally-acquired ( A, C, E, G) or imported ( B, D, F, H) based on a history of overseas travel to a dengue-affected country during the period 3 – 12 days prior to illness onset. Case location was determined from geolocated address information from the Cairns and Townsville public health unit operational databases, where available, otherwise from suburb in the NoCS case record.
