Abstract

Development of efficacious interventions is only the first step in achieving population level impact. Efficacious interventions impact infection levels in the population only if they are implemented at the right scale. Coverage must be prioritised across subpopulations based on the diversity and clustering of infections and risk in society, and expanded rapidly without delay. It is important to prioritise those who are most likely to transmit infection first.
