Fig. 1

Viral sequence ambiguity relative to time since infection. Plot of a probability of zero ambiguous calls and b mean ambiguity percentage if not zero as a function of time from true date of infection to sequencing (in years). The functions plotted are defined for men who have sex with men or heterosexual women with viral sequencing at a ‘typical’ lab (with lab specific variations set to zero). Plots are displayed of the expected function value (black line) and 95% credibility interval (dashed line) over the joint posterior distribution of relevant model parameters as resulting from the calibration dataset
