  author={Tobias E. Hector and Isobel Booksmythe},
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. 

Which ‘imperfect vaccines’ encourage the evolution of higher virulence?

Analysis of the theory in light of recent changes in the understanding of viral biology raises doubts that medicine-driven, pernicious evolution is likely to be common and proposes a more nuanced consideration of alternative models for the within-host dynamics of infections and for factors that limit virulence.

Understanding potential implications for non-trophic parasite transmission based on vertebrate behavior at mesocarnivore carcass sites

This study contributes to filling key gaps in understanding the role of carrion in the landscape of disgust, which may be especially relevant in the current global context of emerging and re-emerging pathogens.

Binding and entering: COVID finds a new home

The features of the receptor-binding domain (RBD) and protease cleavage of the SARS-CoV-2 spike protein that enable Sars-Cov-2 to be a pandemic virus are discussed.



Virulence‐driven trade‐offs in disease transmission: A meta‐analysis *

A meta‐analysis of 29 empirical studies suggests that the current empirical evidence provides partial support for the trade‐off hypothesis, but more work remains to be done on the four core relationships predicted by the theory.

Spatial and temporal dynamics of epidemics of the rust fungus Uromyces valerianae on populations of its host Valeriana salina

The dynamical behaviour of this set of pathogen demes best fit that predicted for a metapopulation with considerable asynchrony in epidemiological patterns between different demes, despite evidence of among-population migration.

Coevolution of hosts and parasites

The authors conclude that such associations may be responsible for much of the genetic diversity found within natural populations, from blood group polymorphisms to protein polymorphisms in general.

Detecting the impact of temperature on transmission of Zika, dengue, and chikungunya using mechanistic models

Temperature-dependent transmission based on a mechanistic model is an important predictor of human transmission occurrence and incidence in tropical and subtropical regions and in temperate areas even if vectors are present.
