The paper analyzes the spread of H5N1 B3.13 in U.S. dairy cattle using genomic data and movement networks, finding that cattle movement, not birds, drives the outbreak.

The paper introduces baltic v1.0, a Python library for phylogenetic tree analysis and visualization, with new features for rooting, reticulate evolution, and composite figures.

This study tracks the emergence and molecular evolution of H5N1 influenza viruses in U.S. dairy cattle, identifying increased mutation rates and positive selection after spillover from birds.

Reanalysis of public environmental metatranscriptomes from the Huanan market links SARS-CoV-2 positivity to one wildlife stall containing raccoon dog, civet and bamboo rat genetic material.

The paper introduces outbreak.info Research Library, a platform that aggregates and standardizes over 350,000 COVID-19 resources from sixteen repositories for easy search and exploration.

This paper describes a method to sequence Zika and other virus genomes directly from clinical samples using multiplex PCR and portable sequencing technologies, achieving complete genomes in 1-2 days.

This study sequenced 110 Zika virus genomes from 10 countries, revealing rapid expansion in Brazil, multiple introductions into other regions, and undetected circulation before confirmed cases.
