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%.

This study models ASFV transmission within swine barns, identifying between-pen contact as the primary route, with nose-to-nose contact contributing most, and aerosol transmission having minimal impact.

This study evaluates PEDV RNA contamination on swine transportation vehicles before and after cleaning, finding pigs-to-market trucks are most contaminated and quaternary ammonium/glutaraldehyde disinfectants are more effective.

This paper uses a mathematical model to identify intensified control strategies needed to eliminate African swine fever from U.S. swine populations within 12 months.

This study models the resource requirements for detecting an ASFV outbreak in the U.S., finding that sample collectors and lab capacity are critical to prevent delays.

The paper models targeted vaccination strategies against PRRSV strains at the barn level, showing that strain-specific vaccines reduce infections, while multiple vaccines may be more effective when strains vary in vaccine response.

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.
