Use of modelling to modify trachoma elimination strategies affected by the COVID-19 pandemic.

Models predict that the negative effects of delayed implementation in trachoma elimination programmes caused by the COVID-19 pandemic will be minimal, except in high prevalence districts where progress may be reversed. During times of change we must stand by our principles of evidence-based decision-making, but also be willing to show flexibility. Slow progress to elimination in high prevalence districts was already a significant challenge to the global programme and mitigation of COVID-related delays with enhanced implementation provides an opportunity to simultaneously address an unprecedented challenge and a pre-existing one.
