Increase in lifetime infectious bites due to behavioural alterations (altered feeding propensity before and after infectiousness). A. Mortality constant across a feeding cycle; B. All mortality associated with feeding; C. Mortality split equality between those two scenarios. The different shaded bars from left to right indicate one to five post-infectious bites. The y-axis is proportionate increase, so the dotted line denotes the situation where behavioural alteration has no impact on transmission.
