Fig 2.
Predicted age-seroprevalence of dengue virus using the catalytic model (blue), and the observed age-seroprevalence with associated confidence intervals (red).
Fig 3.
Number of dengue positive patients enrolled per month and per commune between October 2016 and May 2019.
The vertical dashed lines represent the date the serosurvey (June 2017), and the boundaries of the observed outbreak (September 17, 2018 to March 24, 2019). The plain and dotted black curves represent the model-predicted mean number of cases and confidence intervals, respectively.

Spatial distribution of observed and predicted dengue cases by patch (100mx100m) across the four communes during the observed outbreak, using an ensemble of posterior distributions.
Fig 5.
Percentage of cases averted, by delay in intervention (days), assuming constant effective coverage (0.81) and intervention length (180 days); by type of intervention (Drug control, Vector control), time of application in outbreak (Early (outbreak day = 1), Mid (outbreak day = 52), Late (outbreak day = 92)), and radius of CATI and One-time mass distribution (OTMD).
Fig 6.
Percentage of cases averted by change in effective coverage, assuming constant delay (7 days) and intervention length (180 days) by type of intervention (Drug control, Vector control), time of application in outbreak (Early (day = 1), Mid (day = 52), Late (day = 92)), and radius of CATI and One-time mass distribution (OTMD).
Fig 7.
Percentage of cases averted, by length of application of intervention (days), assuming constant effective coverage (0.81) and delay (7 days) by type of intervention (Drug control, Vector control), time of application in outbreak (Early (day = 1), Mid (day = 52), Late (day = 92)), and radius of CATI and One-time mass distribution (OTMD).

Number of anti-viral episodes with drug (A) and ratio of episodes to averted cases(B), assuming constant effective coverage (0.81) and delay (7 days), applied early (day = 1) in an outbreak.
