Their simulations revealed that between-farm movements accounted for a substantial 71% of disease transmissions, with local spread and vehicular transmission contributing approximately 14% each. Remarkably, vehicular transmission emerged as a crucial route for disease spread, emphasizing the need for a deeper understanding of this aspect.
Implementing a combination of control strategies, including quarantine, depopulation, movement restrictions, contact tracing, and enhanced surveillance, exhibited a positive impact in curbing the outbreak. Simulations incorporating these interventions demonstrated an average reduction of up to 79% in secondary infections within the 140-day timeframe. Encouragingly, approximately 29% of simulations with all control strategies implemented showed no further affected farms during that period.
Despite these promising results, the researchers caution that more investigations are required to refine control measures and fully comprehend the scope of effective intervention. Furthermore, they highlight that the duration of an epidemic may surpass the 140-day timeframe, underscoring the need for sustained efforts and a long-term approach to tackling ASF.
