This week, we are sharing a report from recent PhD graduate Kaushi Kanankege about predicting the monthly risk of PRRS.
Key points
- High risk of PRRS occurrence was observed in counties where >25% of MSHMP farms were fully or partially air-filtered, have high number of hog farms, and have farms belonged to multiple production systems.
- PRRS occurrence association with air filters may be due to attempts to mitigate risk in prevalent areas.
- Further research is required to understand the space-time association of the windborne local spread of the virus and the installation of air filters.
