We report the first Sin Nombre virus (SNV) genome sequences from the Northwestern United States and the first SNV sequences recovered from voles. Analysis of samples collected from 189 individual rode...

WSU graduate student Ricardo Rivero is working to uncover the rules that govern how viruses evolve — insights that could one day help predict viral behavior and guide public health responses. A PhD st...

Phylogenetic studies examining the origins, emergence, and spread of viruses have arguably been one of the most active and successful areas of evolutionary biology and form the bedrock of the flourishing field of genomic epidemiology. This, in part, reflects the ability of viruses, particularly those with RNA genomes, to evolve at rates much greater than their cellular counterparts (1). The rapid rate at which viruses evolve and accumulate mutations enables evolutionary signals to be identified through comparative genomics at short timescales relevant for outbreak investigation and response. The integration of phylogenetics and epidemiology, known as phylodynamics, has become a vital tool in response to numerous viral outbreaks, epidemics, and pandemics, including Ebola (2), Zika (3), and, more recently, COVID-19 (4) and mpox (5).

Dengue fever, a major mosquito–borne viral disease, is transmitted by Aedes mosquitoes and poses a significant global health burden. Despite extensive research, the spatiotemporal dynamics of dengue v...
