a) Poisson models fitted to daily incidence over time, bisected by date of peak incidence (December 14, 2017), Cox’s Bazar, Bangladesh, November 10, 2017 to July 31, 2018. The timing of 3 rounds of MVC are shown as transparent beige bars. b) Estimates of time-varying reproduction number (Rt) for diphtheria cases, Cox’s Bazar, Bangladesh, November 10, 2017 to July 31, 2018. The time period was limited to July 31, 2018 owing to highly unstable estimates of Rt produced thereafter due to the effect of sporadic cases. MVC, mass vaccination campaign.
