Dengue poses a significant burden worldwide, and a more comprehensive understanding of the heterogeneity in the intensity of dengue transmission within endemic countries is necessary to evaluate the potential impact of public health interventions. This scoping literature review aimed to update a previous study of dengue transmission intensity by collating global age-stratified dengue seroprevalence data published in the Medline and Embase databases from 2014 to 2022. These data were then utilized to calibrate catalytic models and estimate the force of infection (FOI), which is the yearly per-capita risk of infection for a typical susceptible individual. We found a total of 44 new publications containing 47 relevant datasets across 20 endemic countries. Together with the previously available average FOI estimates, there are now 280 dengue average FOI estimates obtained from seroprevalence data and 149 estimates obtained from case-notification data available across the world. The results showed large heterogeneities in average dengue FOI both across and within countries. These new estimates can be used to inform ongoing modelling efforts to improve our understanding of the drivers of heterogeneity in dengue transmission globally, which in turn can help inform the optimal implementation of public health interventions.
