摘要
There is ongoing interest in the conditions that favor the 演化 of acute, highly transmissible infections in contrast to chronic ones. Earlier studies typically consider the 演化 of a trait that is constant over the lifetime of an infection. However, for many pathogens, such traits can vary over this course. Here, we address the 演化 of temporal patterns in limited host 族群 sizes, where a trade-off between invasion and persistence can arise. This is of particular relevance to questions on the 演化 of acuteness and chronicity. We ask whether 族群 dynamics of 傳播 at the between-host level could lead pathogen 適應 to favor temporal strategies during the course of infection. To do this, we consider an infection to be composed of multiple stages, allowing each of these to evolve independently under a 傳播-dura
