Figure 1.
Association between virulence and transmission. We show transmission rate (in day−1) as a function of virulence, with virulence measured as: (A) putative host mortality based on the loss of avoidance response to hand capture, which occurs as a result of infection‐induced lethargy and blindness; and (B) mean conjunctival swelling (in pixels) determined from photographs. Points represent jittered raw values; the lines are predicted from the model with the standard error represented by the ribbon.
