Key result
Simulation models of African swine fever transmission among 7,882 pig farms in Vietnam showed that movement restriction between 50% and 75% applied in a timely manner minimized disease spread.
Why the study?
The study was conducted to model scenarios of African swine fever virus transmission among farms in Vietnam and evaluate the impact of control strategies using the North American Animal Disease Spread Model.
Population
7,882 pig farms in the Red River Delta region in Vietnam

May guide ASF control in endemic regions; leaves open prospective validation before practice change.
Timely movement restriction of 50-75% and high biosecurity standards are effective in minimizing African swine fever transmission among pig farms.
Lee et al. (2020) studied African swine fever (n=7,882). Movement restriction was evaluated on African swine fever transmission between farms. Simulation models of African swine fever transmission among 7,882 pig farms in Vietnam showed that movement restriction between 50% and 75% applied in a timely manner minimized disease spread.
