Evolutionary history of Jamestown Canyon virus disentangles complex multi-vector ecology

This study uses whole-genome sequencing and phylodynamic methods to analyze the evolutionary history and ecological dynamics of Jamestown Canyon virus, revealing its slow evolution and transmission patterns.

Investigating the dose-dependency of the midgut escape barrier using a mechanistic model of within-mosquito dengue virus population dynamics

The paper develops a mathematical model of flavivirus dynamics within mosquitoes, showing that higher viral doses and multiple blood feeds shorten the extrinsic incubation period.

Phylogeographic reconstruction of the emergence and spread of Powassan virus in the northeastern United States

This study reconstructs the emergence and spread of Powassan virus lineage II in the northeastern U.S. using genomic data, finding a south-to-north dispersal pattern and population growth.
