Reduced dengue incidence following city-wide wMel Wolbachia mosquito releases throughout three Colombian cities: Interrupted time series analysis and a prospective case-control study
Fig 5
Annualised dengue incidence per 100,000 population in 57 dengue-endemic Colombian cities with population >100,000, 2008 to June 2023.
Coloured filled circles indicate annual dengue incidence in the three cities in the Aburrá Valley where staged roll-out of the wMel intervention was implemented between 2017 and 2021: Bello (orange), Medellín (blue) and Itagüí (green). Open grey circles represent annual dengue incidence in the remaining 54 cities (note the log10 scale on the Y-axis). The horizontal lines indicate the median and interquartile range of dengue incidence among the 57 cities in each year. The vertical dashed line roughly demarcates the pre-intervention and post-intervention periods.
