The massive scale of the global SARS-CoV-2 sequencing effort created new opportunities
and challenges for understanding SARS-CoV-2 evolution. Rapid detection and assessment …

The origin of SARS-CoV-2 has evoked heated debate and strong accusations, yet
seemingly little resolution. I review the scientific evidence on the origin of SARS-CoV-2 and …

The global dynamics of seasonal influenza viruses inform the design of surveillance,
intervention, and vaccination strategies. The COVID-19 pandemic provided a singular …

Here, we combine international air travel passenger data with a standard epidemiological
model of the initial 3 mo of the COVID-19 pandemic (January through March 2020; toward …

Genomic data hold increasing potential in the elucidation of transmission dynamics and
geographical sources of infectious disease outbreaks. Phylogeographic methods that use …

Vast amounts of pathogen genomic, demographic and spatial data are transforming our
understanding of SARS-CoV-2 emergence and spread. We examined the drivers of …

Tracking the spread of emerging pathogens is critical to the design of timely and effective
public health responses. Policymakers face the challenge of allocating finite resources for …

SARS-CoV-2 variants of concern (VOCs) circulated cryptically before being identified as a
threat, delaying interventions. Here we studied the drivers of such silent spread and its …

Despite a rapid expansion of Porcine reproductive and respiratory syndrome virus (PRRSV)
sublineage 8.7 over recent years, very little is known about the patterns of virus evolution …

The continual evolution of SARS-CoV-2 has significantly influenced the global response to
the COVID-19 pandemic, with the emergence of highly transmissible and immune-evasive …
