Fig. 4From: Socio-ecological dynamics and challenges to the governance of Neglected Tropical Disease controlCharacteristic changes in LF dynamics as infection approaches a critical transition point. a Model fits (lines with crosses) to Mf prevalence time series data (open circles) following a MDA intervention. b System slowness as it nears a transition, as evidenced by an increasing lag-1 correlation between subsequent states [30, 42]. Open circles: observed data; crosses: model predictions. Observed data are from Ramaiah et al. [72]; simulation methods used to model the impact of MDA on progression of mf infection towards a site-specific breakpoint threshold as provided in Michael and Singh [14]Back to article page
