Conclusions: In general, a short delay in the programme does not cause major delay in achieving the goals. Impact is strongest in high endemicity areas.  ...  Methods: We used three established lymphatic filariasis transmission models to simulate infection trends in settings with annual treatment rounds and programme delays in 2020 of 6, 12, 18 or 24 months.  ...  Black line shows a non disruption scenario (counterfactual), with a baseline prevalence of 15%. Red line shows a no mitigation scenario, where a one year delay takes place in 2020.  ...
