Abstract

Research predicting the impact and spread of infectious disease has been heavily influenced by the idea of an evolutionary trade-off between a pathogen's virulence and its transmission rate. In a meta-analysis of the key underlying relationships, Acevedo et al. (2019) highlight the surprising lack of empirical evidence for this influential hypothesis.

摘要

预测传染病的影响和传播的研究受到病原体毒力与其传播率之间存在进化权衡这一观点的严重影响。在对关键基础关系的元分析中，Acevedo 等人（2019 年）强调了这一有影响力的假说缺乏令人惊讶的经验证据。
