Parameter estimates of systemic infection kinetics for each DENV isolate.

Parameter values for each isolate were inferred from the cumulative change in the proportion of mosquitoes with a systemic DENV infection over time post exposure using model optimization. K is the saturation level and represents the maximum proportion of mosquitoes with a systemic infection. B is the slope factor and represents the maximum slope of the cumulative function scaled by K. Δt is derived from B and represents the time required to rise from 10% to 90% of the saturation level. M is the lag time and represents the time at which the absolute increase in cumulative proportion is maximal, which is also when the systemic infection prevalence equals K/2. Background shading (grey scale) indicates the best isolate groupings as determined by the AIC method.
