Modeling the impact of optimized airflow and sick pen management on the spread of infectious diseases in swine barns

This study models how optimized airflow and sick pen placement in swine barns affect disease spread, finding that ventilation adjustments and strategic pen placement can reduce disease transmission by up to 43.2%.

Analyzing the intrastate and interstate swine movement network in the United States

The paper analyzes swine movement networks in the U.S. to identify disease spread dynamics and evaluate control strategies based on shipment data and network metrics.

Estimating the effectiveness of control actions on African swine fever transmission in commercial swine populations in the United States

This study evaluates ASF transmission in U.S. swine populations using a spatially-explicit model, finding that between-farm movements are the primary transmission route and that combined control actions reduce secondary cases by 79%.

Modeling foot-and-mouth disease dissemination in Brazil and evaluating the effectiveness of control measures

This study models FMD spread in Brazil and evaluates control measures, finding vaccination and depopulation reduce outbreak magnitude and duration.

A discrete-time survival model for porcine epidemic diarrhea virus

This paper develops a discrete-time survival model to quantify PEDV spread dynamics, finding strong associations between local transmission, pig movement, and disease spread.

Assessing epidemiological parameters and dissemination characteristics of the 2000 and 2001 foot-and-mouth disease outbreaks in Rio Grande do Sul, Brazil

This study analyzes the 2000 and 2001 foot-and-mouth disease outbreaks in Brazil using epidemiological data and Bayesian modeling to estimate transmission parameters and movement patterns.

Modelling and assessing additional transmission routes for porcine reproductive and respiratory syndrome virus: vehicle movements and feed ingredients

This study models multiple transmission routes of PRRSV, finding that pig movements and farm proximity are the main transmission pathways, while vehicle networks and feed by-products contribute less.

Modeling the role of mortality-based response triggers on the effectiveness of African swine fever control strategies

This paper models ASF control strategies by analyzing how mortality-based triggers affect epidemic duration and spread, showing that backward movement tracking outperforms ring quarantine zones.

Modeling the transmission and vaccination strategy for porcine reproductive and respiratory syndrome virus

This study develops a stochastic epidemiological model to analyze PRRSV transmission dynamics and evaluate vaccination strategies across different pig production phases.

Nairobi Sheep Disease Virus: a historical and epidemiological perspective

This study identifies regions at risk for Nairobi Sheep Disease virus (NSDv) circulation by analyzing environmental factors and literature data.

Porcine reproductive and respiratory syndrome virus dissemination across pig production systems in the United States

This study investigates PRRSV dissemination across U.S. pig production systems, finding frequent cross-system transmission and highlighting geographic factors influencing spread.

Quantifying the dynamics of pig movements improves targeted disease surveillance and control plans

This study uses temporal pig movement data to model disease spread and shows targeting high-degree farms reduces epidemic size significantly.

Phylogeography of equine infectious anemia virus

This study maps the global spread of EIAV using phylogeographic analysis and bibliometric review, identifying Hungary as the likely origin and highlighting research disparities.

How to make more from exposure data? An integrated machine learning pipeline to predict pathogen exposure

This paper develops a machine learning framework to predict pathogen exposure in wild lions using ecological data, finding non-linear patterns and variable interactions that improve predictive performance.
