In “Dengue Endemicity, Force of Infection and Variation in Transmission Intensity From 13 Endemic Countries” by Nealon et al [J Infect Dis 2020; jiaa132], the advance online publication contained three errors in Table 3, introduced through a Stata coding error. The legend for Figure 2 also incorrectly described the confidence intervals in the figure. The correct table and figures are provided below, and are correct in the printed version.
Table 3.
Ages at Which 50% and 80% of Children Become Dengue Seropositive, Per Country, Using Constant or Age-Varying Models
| Median Age at Seroconversion, y (95% CI) | 80th Percentile Age at Seroconversion, y (95% CI) | |||

Best-fitting models are highlighted in bold.
Figure 2.
Observed seroprevalence by age (circles) and 95% confidence interval (CI), adjusted for clustering (spikes) and estimate seroprevalence assuming constant force of infection (FOI) (solid line) and 95% CIs (shaded area). Dotted lines correspond to estimated seroprevalence under an assumption of age-varying FOI.
The authors regret the errors.
